The G'zOne mobile phone has been revived in response to the voices of hot fans. The 4G LTE mobile phone "G'zOne TYPE-XX" commemorating the 20th anniversary of the G'zOne brand was released by au on December 10, 2021. In G'zOne TYPE-XX, KDDI, Casio Computer, and Kyocera collaborated. Casio, which withdrew from mobile phone manufacturing, was in charge of the design, and it was developed under an unusual system in which Kyocera manufactures it. We asked Mr. Takayuki Kondo, who was in charge of planning for KDDI, and Mr. Toki Ido, a designer of Casio Computer Co., Ltd., about the secret story behind the development. ● Casio also wanted to continue toughness mobile phones——In this “G'zOne TYPE-XX”, Casio has revived the G'zOne brand since it withdrew from the mobile phone business at the end of 2013. Mr. Ido First of all, I would like to take the opportunity of this interview to apologize to Casio users. As a designer at Casio, I was involved in the design direction of almost all models from the first mobile phone model "C303CA". I think that many users suddenly thought that Casio's withdrawal from the mobile phone business in 2013 was abrupt. It is until then that one manufacturer with a small market share has withdrawn, but since the first model "G'zOne C303CA" in 2000, we have been enthusiastically working on product development with the idea of valuing hot fans. bottom. At the time of Casio's entry, Japanese manufacturers' mobile phones were in their prime. Casio was in a position to question the significance of its existence because it was the last to enter the market. The toughness mobile phone G'zOne is a model that is truly Casio-like, and it is also an EXILIM mobile phone that makes use of its knowledge as a digital camera maker. There may be a small number of people who have adopted values such as genderless and ageless, but there are many core fans. For Casio mobile phones. When Casio withdrew, some users were wondering what to do with the next model change. In particular, many people used G'zOne for work, so I thought I was really sorry. After that, Mr. Kondo started to release a new toughness series TORQUE with Mr. Kyocera. As a personal feeling, of course I wanted to continue Casio's toughness mobile phone, but I also think that it saved me. ——I think it was a challenging initiative to revive a brand that once withdrew from smartphones by manufacturing it from another manufacturer. Please tell us the background behind the commercialization. Mr. Kondo The reason for the commercialization was the voice of the customer. At KDDI, we are always considering listening to customers in questionnaires and group interviews as a reference for product development, but recently we have received many comments that "the lineup of feature phones is small." I did. In a world where smartphone shifts are advancing, we continue to provide feature phones, but anyway, the lineup configuration has many general models with thin features so that many customers can pick it up. It was becoming. We received harsh voices from customers, such as "the lineup is boring", "I want a feature phone that is sharper like it used to be", and "I think I'm neglecting the feature phone". I was there. ● 98% of G'zOne users want G'zOne again —— au has introduced a wide variety of mobile phones, especially in the 3G era, but this time, we have set a white arrow on the G'zOne brand. Why? As Mr. Kondo said, KDDI has continued to commercialize design-focused mobile phones, including the au design Project. Casio has other brands like EXILIM Keitai, but there were special circumstances for G'zOne. At au, we are conducting continuous user surveys, and as part of that, we are also researching the models that users want to replace next. In the process of analyzing such surveys, interesting results emerged. Many of the users who are currently using the G'zOne series feature phones would like to have the same manufacturer and brand next time. According to the data just before the release of "G'z One TYPE-XX", 98% of the people wanted "Next G'z One". ——Au continues to sell the Kyocera “TORQUE” series as a toughness model option. In 2018, we also introduced the feature phone type "TORQUE X01", but why did you dare to revive the G'zOne brand? Mr. Kondo That's right. The category of toughness model is au, and even after the withdrawal of G'zOne, it continues to be introduced in the form of taking over to Kyocera's TORQUE brand, and a certain number of people who used the G'zOne series in the past will move to the TORQUE series. We have you migrate. On the other hand, the feature phone type G'zOne has many core Casio fans, and has been using feature phones from the 3G era for many years. There are some customers who want to use G'zOne up to 3G stop even if they are using the previous model, and some of them are "G'zOne in case something goes wrong" despite the toughness model. I have a spare for TYPE-X. " And in March 2022, au plans to stop the 3G service ahead of other companies. In other words, the G'zOne mobile phone in the 3G era will no longer be available, but there are some hot G'zOne fans who are currently using it. I thought that au answered that long-awaited answer, so I hit Casio's gate. ——A lot of talk was gathered before and after the launch in December 2021. How is the response after the release? Also, what kind of person is purchasing it? Mr. Kondo We have received a lot of feedback since we announced the release in August 2020. Many people said that they actually purchased it. The purchasers are in their 40s and 50s, and the majority are men. After all, G'zOne is the 20th anniversary, so if you know 20 years ago, you will be a generation higher than that. ——I think that the number of people who use feature phones alone in the smartphone era is decreasing, but is there still a demand for them? Mr. Kondo That's right. Of course, there are people who have two smartphones, but in the interview I interviewed, there were quite a few people who had two smartphones, "notebook PCs and feature phones." Those who use it in this way have high information sensitivity, and notebook PCs are used to collect and send information on the Internet. Still, it seems that feature phones are preferred because feature phones are the best way to keep in touch. Also, many people who like button-shaped mobile phones are using it for work. People who are engaged in on-site work such as farming and fisheries have said that the button type is good. ● The concept design was developed in two months with “Mucha swing” —— When did au consult with Casio about the design production of G'zOne? Mr. Kondo I visited Mr. Ido for the first time in 2017 at the end of 2017. However, at that time, I did not have a formal proposal to "make a revival version of the G'zOne model", but just told the current situation a little. After that, at the beginning of 2018, Casio made the first prototype design. However, even at that timing, not only commercialization but also Kyocera's manufacturing system was not decided, but first of all, the exterior design was based on the theme "What if I made G'zOne with the current design?" I had you make a mock. ——How did Casio take it at that time? Mr. Ido Casio was in a position to withdraw from the mobile phone business once, and G'zOne users were also in the process of moving to TORQUE, so I thought that the role was over. However, when I heard from Mr. Kondo that tens of thousands of people remain in G'zOne, I wanted to do something about it, so I became involved in design production. In the first half of 2018, I made a concept design and handed it to KDDI. ——The concept design as of 2018 is also sophisticated, and it looks like the product version. Mr. Kondo Even if you take a quick look, you can see that the circle display on the back is a symbolic icon like G'zOne. The design incorporates the G'zOne character in every detail, such as the adoption of a round numeric keypad with the motif of "C303CA," which is the first G'zOne machine, so I think the finish is suitable for the 20th anniversary. increase. Mr. Ido Actually, at this time, the order was terrible, "Please make it in two months" (laughs). Mr. Kondo Excuse me at that time (laughs). For the first design mock, in early 2018, we handed over the TORQUE mobile phone and asked us to make a design mock with a similar size. Initially, rather than commercializing it, we put out a full-scale mockup as a reference for research, and made it with the intention of knowing the interests of users. I knew that this kind of product design wasn't something that popped out, and that it took a lot of time from concept formulation to idea consideration, but with our research plan, it was quite a mess. I was asked to do ... (laughs). Mr. Ido Generally, when making such a design mock, it takes at least 3 months to make it into a shape because it takes 2 months just to make the exterior design on the drawing, but I refuse. Once it's done, it's over, so I decided to finish it with a limited express. ——Why did you get it in two months? Mr. Ido I was able to deal with the mess because I was actually continuing to design mobile phones within Casio. I didn't mean to re-enter the mobile phone, but because the mobile phone was a well-designed teaching material. A mobile phone is a "rich" product design packed with complex elements, and is very suitable as a rite of passage for new designers. In particular, the recent design trend is a simple and minimum route, so it is difficult for young people who have graduated from beauty college to be able to design like this. It's not a traditional performing art, but Casio also has a G-SHOCK, so this kind of design must be extinguished. As a result, by continuing to design mobile phones, the material in the drawers was accumulated, and we were able to respond to Mr. Kondo's request. ● Kyocera is persuaded with “the power of things” —— This time, Kyocera is in charge of designing and manufacturing. At what point did you join? Mr. Kondo I think it was around the end of 2018 to the beginning of 2019. Initially, Mr. Casio made the design of the concept model, but there were several hurdles until commercialization, including KDDI's internal agreement, just by making the cold mock. 2018 was a year of exploring the possibility of commercialization by accumulating research based on design mock. First of all, as a voice to the manufacturer, I thought it would be good for Kyocera, who is making the TORQUE series, to participate from the beginning, but there are also different issues. There is ... ——How is Kyocera's reaction? Of course, of course, you would say, "Why should I make G'z One even though I still have the TORQUE series?" Even if I explained that I didn't want to return the smartphone from the TORQUE series to the G'zOne series, I wasn't convinced smoothly. I had you look at various data to get involved with Kyocera, and I asked the upper management to explain it, and I managed to get their support. ——You've persuaded me, didn't you? Mr. Kondo Actually, G'zOne TYPE-XX has a "back theme". I want people who don't like TORQUE to use it. Even after Casio's withdrawal, au continued to introduce the TORQUE series as a successor to the toughness model, and a certain number of users have switched to TORQUE. Even so, there are still some fans who continue to use G'zOne. I also love G-SHOCK, so there are many things that I sympathize with the feelings of fans who say "Toughness is Casio". I think that Casio was able to make a toughness mobile phone 20 years ago, not only because of his image but also because of Casio's high level of technical skills for toughness design. On the other hand, from the standpoint of the person in charge of planning, there was still the conflict of "Why can't you use TORQUE?" Taking the opportunity of G'zOne TYPE-XX, "Design is Casio, Contents are Kyocera", I wanted Kyocera's toughness model to use it as a back theme. Mr. Ido This time, Casio is mainly involved in the design and graphics of the exterior, and since it is manufactured by Kyocera, in a sense, it can be said that the contents are TORQUE. There is also talk about whether Casio can design it and give it the name G'zOne, but when I hear the voices of users, there are many "fans of Casio's G'zOne design", and I hate TORQUE without eating it. It seems that some people said that. By delivering a collaboration model of three companies, TORQUE x G'zOne x au, I hope that you will be able to know the goodness of Kyocera's toughness mobile phone. ——What is the reaction of the Kyocera design team during development? Mr. Ido Actually, the design team of Kyocera worked very positively. Is it "the power of things"? It seems that he picked up the mockup and wanted to make it. Casio also placed a lot of orders in detail, but I was a little surprised and polite. It took a long time from making the mockup to commercializing it, so I was able to spend a considerable amount of time redesigning it. Mr. Kondo Now, to put it secretly, I had you proceed with a little flying preliminary examination before the stage of business negotiations with Mr. Kyocera, that is, before it was decided to participate in manufacturing and development. A person from the design department of Kyocera said, "I definitely want to do this project, so please do not bring it to other companies." Perhaps it was because they took the time to knead it that they reached the point of commercialization in a form that was quite similar to a mockup. ● Improved the design by tagging with Kyocera —— You refined it while interacting with Kyocera. Mr. Kondo There were also shape changes and functions that were not in the concept design. He worked closely with the Kyocera design team to Dane. For example, there are 6 protrusions called "protectors" on the front. By attaching this, the impact is not directly transmitted to the metal parts when dropped, and damage is not given. Mr. Ido This is the part where Casio improved the design in response to a request from Mr. Kyocera, "I want you to attach another part to a higher place on the sub LCD." It was a difficult attempt to brush up without spoiling the appearance. Mr. Kondo Also, the back is designed to let air out like a duct, but this is also where the Kyocera design team worked hard. Actually, this duct is not just a dummy, but functions as an air passage hole. There is a temperature sensor for the thermometer in the back of the duct so that the outside temperature can be displayed. Mr. Ido The G'zOne series has a motif of motor sports, but here I attached this duct with the image of a sports car midship engine. The Kyocera designer who saw this design suggested, "Can I use this duct for something?", And this is an improved part. Other than that, there was time before moving to mass production design, such as marking the ring of the circular display on the back like an index of a watch, incorporating cubic curves everywhere to make it a smooth shape, etc. So, I'm tinkering with the details. ——It's like G'zOne that you can display the clock and compass on the sub LCD. Mr. Kondo The sub-display is the first G'zOne to have a completely circular display. Information such as clock, compass, barometric pressure, and altitude can be displayed on the back. Mr. Ido A notification LED is installed to illuminate the display, and it lights up when charging or receiving an incoming call. It looks cool when you look at it in the dark. ——I got the impression that the numeric keypad does not get lost when pressed in a round shape. Mr. Kondo This time, we have adopted the essence of the first machine "303CA" and adopted a round key. The design is very suitable for toughness models because it is hard to mistakenly operate with the next key and it is easy to press even with work gloves. Mr. Ido If you simply place the round keys, you will get the impression that the appearance will be scattered. Therefore, I try to give each key a sharp edge to give it a condensed look. I've always wanted to do this kind of design, but I couldn't do it with Casio's design at the time. At the time of G'zOne TYPE-X, it was necessary to narrow the key pitch to secure a waterproof area. Kyocera's design was a material with a wide key pitch and a design challenge. ● Use "12 colors of black" properly for solid black --- There are two color variations, "liquid green" and "solid black". Mr. Ido The green color "liquid green" is "G" 10 years ago. As a color that inherits "zOne TYPE-X", Casio strongly requested it and added it to the color lineup. The green color of this exterior was difficult to develop. With 10 years of technological evolution, this bright color is finally possible. In the previous generation G'z One TYPE-X, greenish silver is coated in light green, but in this TYPE-XX, two types of pearl paint are layered on the light green fabric to shine light. It has a transparent green color. We were able to achieve this color because the fabric used for the base has been improved and the color has improved. Mr. Kondo Another color is "Solid Black". Black is also very popular in toughness, so I chose to add it as a standard item. Mr. Ido The visual impact is green, but some people may get bored while using it. Black is hard to throw away as a standard color that you won't get tired of. However, it is not interesting to make ordinary black, so this solid black is packed with a lot of attention. The black paint used for the exterior panel is said to be "the first paint used in Japan" according to the person in charge of color selection, and it contains fine particles and is finished with a smooth feel. Copper (copper) is added to the color to create a luxurious atmosphere without simply submerging it in black. If you take a closer look, you can see that even if black is black, there is glossy black, there is grain black, there is rough black, and the texture differs depending on the part. In fact, in solid black, 12 colors with the name "black" are used properly. I had plenty of time to polish the design, so I was particular about it. In G'zOne so far, black colors are used at most 3 to 4 colors, so I think it is almost unprecedented to use 12 colors as well. The person in charge of designing Kyocera was also surprised, "Is it used properly so far?" (Laughs). Mr. Kondo It is a common usage to use black properly to change the appearance of gloss, but it is unusual to use 12 patterns of black. ——The black color is used so that the ring in the middle stands out. Mr. Kondo There is a sense of mass as black, but the three-dimensional effect is also felt properly. Mr. Ido It's not just black. ——In the G'zOne series, red is an impressive color along with green, but it is not included in this lineup. Mr. Ido That's right. We received quite a few voices asking "Why is there no red?" To tell you a little bit about it, this exterior panel is actually just a cowl, a decorative part. Even if this exterior is torn off, both waterproof performance and toughness performance are ensured. I will preface it at my own risk, but if you have a custom arm, you may be able to enjoy it by removing the panel and painting it in your favorite color. At first glance, it looks like it is screwed, but this screw is a decorative screw, and it is actually fixed with adhesive, but it may break if you apply force when removing the panel. Please work with caution. Mr. Kondo However, repainting is not covered by the product warranty and is not recommended by au, so please forgive me. ● The desktop holder is a traditional vertical type, and even users who have purchased three units—there are plenty of peripheral devices. Mr. Ido Mr. Kondo is particular about such accessories. Even one neck strap is casually decorated with the G'zOne logo and is elaborate. Mr. Kondo Options include a replacement battery, a 2-way strap, and a desktop holder. The 2-way strap can be attached to a bag or belt with a carabiner, or it can be hung from the neck as a neck strap. The included strap case can be used to store spare batteries, earphones, and earphone jack adapters for carrying around. ——The desktop holder is a type that can be placed vertically. Mr. Ido Actually, when you insert this into the desktop holder, the charging LED is hard to see. This is my fault ... (everyone laughs). Mr. Kondo The desktop holder of the G'zOne series was a type that was placed diagonally. Mr. Ido The TORQUE mobile phone developed by Kyocera, which manufactured this model, used a horizontal desktop holder. This time, Casio requested "I want to be able to charge it vertically" and developed this holder, but the G'zOne TYPE-XX had a charging terminal on the side like the TORQUE mobile phone. Became a bottleneck. Since the charging terminal on the side was left as it was and designed to stand vertically, it became difficult to see the notification LED display that illuminates the sub LCD downward. As a design designer, I had to fix it, but I overlooked it. We would like to take this opportunity to apologize to our users. Mr. Kondo The fact that the desktop holder is vertical has been well received by users as "It seems to be G'zOne." Some people said that they purchased as many as three. In addition to home and work use, it is said to be used by inserting it into a car drink holder. Mr. Ido The width of the holder itself has become a little wider, which I originally wanted to fix. The original prototype desktop holder was thick like a mortar for making rice cakes, so it is still quite slim, but because the desktop holder was designed with the charging terminal on the side as it is, it became thicker. ● “That Penguin” will also make a special appearance——Is the app selected by Casio? Mr. Ido Casio's involvement is centered on the exterior design, and only some graphics are provided for apps and UI (user interface). Various functions such as Outdoor Apps are based on Kyocera's "TORQUE X01". Ten years ago, G'zOne TYPE-X was equipped with a tool application called "G'zOne Gear", but since Ikansen Casio has withdrawn from mobile phone manufacturing, it is possible to install the one at that time as it is. I can't go. However, Kyocera's Outdoor Apps also support temperature and compass sub-displays, so I wonder if it can be used by G'zOne users to some extent. ——What part of Casio is involved in graphics? Mr. Ido's wallpaper contains more than 10 pieces, including those with the motif of motor sports, which is the theme of G'zOne. We also offer graphic design in major apps. ——There is “that penguin” in the stopwatch, but how did you come in? Mr. Ido It's a Casio penguin. Kondo-san's hobby (laughs). Originally a character born from "Heart Craft" which was the design concept of "A5512CA" released in 2005, it has no official name, but it was loved as "Kashipen". Although it is a character that has nothing to do with the G'zOne series, I was asked to make a "special appearance" with the hope of Mr. Kondo. Mr. Kondo: We do not put it out entirely, but rather position it as a "hidden character". There are other scenes besides the stopwatch, so please look for them. ●スマホが主流の市場で開発に難航—— 開発期間について確認させてください。 2018年初に最初のデザインを作って、発売は2021年12月と、ずいぶん間がありますね。井戸氏 カシオとしての作業は、製品開発の最初と最後の期間に凝縮されています。最初2カ月にぎゅっとデザインコンセプトを詰めて、その後長い間京セラの設計チームと一緒とともに、機能の作り込みなどをじっくりと進めていました。その後しばらくはKDDIとのやりとりがなく、量産化をしないものかと思っていました。 2020年に入って、首をひねっていたところ、2020年初に製品化が決定して、最後のグラフィック制作を一気に進めて、製品化といった流れです。 —— G'zOneの20周年は2020年でしたから、20周年を過ぎてしまったということですね。近藤氏 ユーザーにはお待たせして、大変申し訳ありませんでした。 2020年の時点でKDDIとしてはまったく毛色の違う課題に直面しており、量産化をためらいました……。スマートフォン時代ならではの難しさとして「プラットフォーム選定」の課題があります。プラットフォームとは、チップセットとOSを組み合せた、携帯電話の基盤となるパッケージです。チップセットはスマートフォンが主流となって以降、長期間に渡り安定供給される製品がかなり限られる状況となってきています。一方で、OSにもバージョンごとにデバイス開発向けのサポート期間が設定されており、この組み合わせがプラットフォーム選定を困難にしていました。 Androidスマートフォンであれば、毎年のように最新のチップセットが入手でき、OSバージョンアップもそのチップセットに合わせた構成にできます。一方で、ケータイ型端末、つまりフィーチャーフォンでは「長く使えること」も価値であるため、製品の発売後に、どのくらい安定供給できるかも重要な点となっています。となると、必然的に選べるチップセットとOSの組み合わせは限定されています。もともとG'zOne TYPE-XXの発売目標としていた2020年はちょうどKDDIの現行フィーチャーフォン向けのプラットフォームの端境期にあたり、新しいチップセットとOSの組み合わせを選定する必要がありました。その当時の現行機種と同じプラットフォームで発売すると、チップセットの供給が途絶えてしまう可能性がありました。一方で当時、長期間に渡る供給が見込めるチップセットを選んでいたら、対応するOSのサポート期間が短くなってしまうとジレンマがありました。一時期はKDDI社内で、ケータイ端末そのものを作れなくなるのではないかという議論にもなっており、G'zOne TYPE-XXだけでなく、「GRATINA」や「かんたんケータイ」のような製品も終了せざるを得ないのかという状況にありました。プラットフォーム選定に関する課題の検討に1年以上を要してしまい、その間はカシオさん、京セラさんにはお待ちいただくことになってしまいました。 —— その課題が解決したのが2021年ということですね。近藤氏 はい。デザインもメーカーも決定したところで、プラットフォーム選定という新たな課題が生じてしまったのが、発売が遅れた要因でした。 2020年末にようやく最適なプラットフォームを設計できる見通しが立ち、2022年3月の3G停波のタイミングにあわせて、開発を加速化させました。 G'zOne TYPE-XX で採用したOSとチップセットの組み合わせは、今後長期間、安定して供給する体制としてはベストな組み合わせだと考えています。 ●カシオが携帯事業に再参入する考えはない—— auでは2022年3月に3Gが停波し、しばらくは4G LTEメインのネットワークになります。今後は5Gへの移行も進んでいく中で、折りたたみ型ケータイはどのように続けていくのか、お考えをお聞かせください。近藤氏 フィーチャーフォンの5G化などで、具体的に決定している方針はありません。現段階では、採用しているディスプレイサイズやチップセットの組み合わせから、4G LTEケータイとして設計するのがベストだと判断しています。ただし、今後のネットワークの進化や部品調達の状況によっては、5G化の可能性もゼロではありません。井戸氏 5Gはかなり高機能になってきますから、仮に現在調達できる部品で構成すると、10万円を超えるような価格になってしまうかもしれません。少数でもフィーチャーフォンを欲しいという方はいらっしゃるとは思いますが、10万円超の価格でビジネスとして成り立つかというと、難しいでしょう。 —— カシオは約9年ぶりでG'zOneブランドを復活していますが、携帯電話とどう関わっていきたいか、今後の方針はありますか。井戸氏 カシオとして、携帯電話事業に再参入するという考えは全くありません。今回のG'zOne TYPE-XXもあくまで「京セラ製」で、カシオは商標許諾と製品デザインという立場で参加しています。ただし、もし、G'zOneが非常に好評で予想以上に売れて、第2弾のデザインをお願いされたら、それはお受けするかもしれません。 —— カシオのスマートウォッチやTORQUEと連携するといったコラボレーションの可能性があると面白いと思うのですが、今後の方針はありますか。井戸氏 実現すると面白いですよね。現時点ではカシオとして具体的に決まっていることはありません。とはいえ、今回のG'zOne TYPE-XXをきっかけとして、KDDIさんや京セラさんとのいろいろなコラボレーションへと発展していく可能性もないとはいえません。いろいろな夢がこの機種で広がりましたよね。近藤氏 お願いしたKDDIの側の人間ですが、異例のコラボレーションだったと思いますね。 —— G'zOne TYPE-XXの開発に当たっての興味深いお話をいただき、ありがとうございました。 「モノの力」という言葉が強く印象に残りました。最後に、開発を終えての実感を改めてお聞かせください。井戸氏 モノの力で集結したのは、カシオのデザインチームや京セラの設計チームだけではないんです。今回、コロナ禍という事情もあったのですが、携帯部品メーカーも国内メーカーの部品を多く使っています。中には既に携帯電話向け部品から撤退していた会社が、数年ぶりに再登板してこの製品のために起こしていただいた部品もあります。いろんな技術者の方が「ぜひこのモックアップを形にしてみたい」と塗料を作ってもらったり、金属を加工してもらったり。塗料、成形、加工メーカーといろいろなところからベテラン技術者が再結集して、G'zOne TYPE-XXを作り上げました。近藤氏 国産の折りたたみケータイが主流だった3G時代は、国内でもボタンやヒンジのようなパーツを作れるメーカーさんがたくさん存在しましたが、スマホシフトが進んだ現代では、部品メーカーさんも携帯電話向けの製造から撤退していたり、そもそもメーカーさん自体が無くなっていたりするような状況となっています。折りたたみ機構やサブ液晶もある折りたたみケータイは、部品点数で言えばスマートフォンよりも圧倒的に多く、複雑な構成の製品です。こうしたデザインを形にして、モノを作りきるという点では、困難な時代に入ってきたなと、製品化を通して実感させられました。
