Japan's Game Dev/Co Tokyo 23 Wards - Backloggdpedia

List of game companies in the Tokyo 23-ku, Japan's capital city. The order of the textual information is: chihō/region and ken/prefecture, company name (in bold) and my comments. There is also some silly gossipy information and comments I have written, but please skip over them. The game titles were chosen at my own discretion, as I consider them to be representative of the target game company. So, if you have any objections, please give your opinion in the comments section.

Map of all Japan: simplified ver1, simplified ver2, Tokyo-to Map
Note1: 地方/chihō = region, 都/to = capital city/metropolis, 府/fu = prefecture, 県/ken = prefecture, 市/shi = city, 区/ku = ward
Note2: Games not registered with the IGDB, publisher companies, port development, some development support, and game companies that only make chess/mahjong games and educational games were excluded.
Note3: When the list was initially drawn up, the intention was to exclude eroge/adult game companies. But then I thought, "What the hell are Enix, Nihon Falcom and Koei in the early days?" and so it was decided to include eroge-companies in the list. In addition, only eroge-companies that had all-ages ports and known addresses were included in the list.
PS: To be honest, compiling this list of Tokyo's 23 wards was no fun at all. In this sense, I only enjoyed the moment when I realised that there are, or used to be, game companies outside Tokyo, in so-called chihō that I didn't know existed.

Unimportant trivia. Miyazaki Hidetaka/宮崎英高 is a fan of the Fate series. In particular, he says that Tohsaka Rin is his favourite character. https://fate-15th.com/message/ By analogy with this evidence, the review's suggestion that Miyazaki Hidetaka is a masochist is probably correct.

The same president and the same family of companies as Broccoli.

The company is apparently developing Valkyrie Elysium, the new Valkyrie Profile. To dig a dead child all the way out of its grave! Why would they do something in such bad taste?
千代田区/Chiyoda-ku
アクワイア/ACQUIRE
I only had an image of them making things like Tenchu and Samurai Road. Who could have predicted that they would make an RPG like OCTOPATH TRAVELER and make it a hit?
新宿区/Shinjuku-ku

スパイク・チュンソフト/Spike Chunsoft
Today Spike Chunsoft is no longer in its former glory and is now a mere publisher. Spike Chunsoft's only value in Japan is to oversee high-quality localisation of foreign games. Wicher3 is probably the best work of them all. This Japanese translation of Witcher 3 is probably one of the three best translations of a foreign game ever. I think I enjoyed Witcher 3 to the fullest thanks to Spike Chunsoft and Satoru Honma, who was in charge of the translation. Thank you Spike Chunsoft, thank you Honma-san. If you want to play The Witcher 3 in a language other than your native tongue, I recommend Japanese. Unless you are one of those people for whom all Japanese audio sounds like anime. In addition, it should be noted that the Japanese translation of Disco Elysium was also handled by Spike Chunsoft, but the quality of the translation was neither good nor bad. I perceive Zaum is dead on my PERCEPTION(SIGHT & HEARING).

ネバーランドカンパニー/Neverland Company
2014 Bankrupt. I thought about choosing Lufia & the Fortress of Doom/Estpolis Denki, but it is indeed old, so I chose Rune Factory4.
文京区/Bunkyō-ku
イメージエポック/IMAGE-EPOCH
2015 Bankrupt. Past Data East. The end that ATLUS would have met without Sega. IMAGE-EPOCH's Mikage is president of the following One or Eight company.
渋谷区/Shibuya-ku
スパイク/Spike
The company merged with Chunsoft in 2012 to become Spike Chunsoft. In Japan, the company was known for the Way of the Samurai series and Shinobi-do, but has become a game company with only Danganronpa as its only well-known title.
千代田区/Chiyoda-ku
キャトルコール/Cattle Call
A games company built around a group of former Data East developers. After several years, they produced MM3, MM2R and MM4.
神奈川県 横浜市/Kanagawa-ken Yokohama-shi → 目黒区/Meguro-ku
モノリスソフト/MONOLITH SOFTWARE
1999, Takahashi Tetsuya of Xenogears left Square and created this company under the umbrella of Namco. Internal political turmoil in Xenosaga 1-3 nearly bankrupted the company. It is tacit knowledge among Japanese Xenogears fans that Xenosaga 2 was the most dangerous time. 2007, became a subsidiary of Nintendo.
新宿区/Shinjuku-ku
みのり/minori
2009 Dissolved. The only thing I know about this game maker is that Shinkai Makoto made the OP. Shinkai Makoto's comments for Minori's dissolved.

Naka Yūji's company, known for its sonic series. As of 2022, it is in dispute with Square Enix.
豊島区/Toshima-ku
アルファユニット/AlphaUnit
2021 Bankrupt
港区/Minato-ku
メイジス/MAGES.
MAGES is represented by Shikura Chiyomaru, a former employee of Human. The company has been flying low in the Steinsgate wind ever since Steinsgate hit the jackpot. There will probably not be a second jackpot. Also, Shikura here is very arrogant and often causes trouble, and I predict that he will cause trouble again in the near future. The next person to fly is Shikura. Fly high in the sky. Aim: Future Nagoshi.
渋谷区/Shibuya-ku

千代田区/Chiyoda-ku
フロントウイング/Frontwing
新宿区/Shinjuku-ku
チュンソフト/CHUNSOFT
A games company founded by Nakamura Koichi in 1984 when he was a university student. Nakamura Koichi joined forces with Horii Yuji to program Dragon Quest from 1 to 5. His work on Dragon Quest, Torneko's Adventure, Otogiriso and Kamaitachi no Yoru has had a major impact on Japanese video game culture. Nakamura Koichi is not well known abroad, but many consider him a great game creator within the Japanese game industry.

パオン/PAON
PAON only acquired the intellectual property rights to the glory of Hercules and, unlike Metal Max, has no staff from the Data East days. Therefore, the DS version of Hercules' Glory has little in common with previous titles. Only the scenario writer is the same. Nojima Kazushige from FF7.
渋谷区/Shibuya-ku
WOW Entertainment(AM1) + Overworks(AM7) →セガワウ/SEGA WOW
Development company formed from the merger of SEGA AM1/WOW and Overworks, which programmed games for Sakura Wars; ceased to exist in 2004 as a result of SEGA's reorganisation.

2007' KOTY(Kusoge of the year).
江東区/Kōtō-ku
トライクレッシェンド/TRI-CRESCENDO
Sibling company of tri-Ace. This article shows that the feud has been lost, as they helped produce the game at Tales of Symphonia Chronicles in 2013. So it would be sterile and silly to measure the superiority of either Star Ocean or Tales. I mean, it's funny how both series seem to die.
台東区/Taitō-ku
エグザム/EXAMU
2020 inactive. Development, operation and support of ongoing titles were transferred to 'Team Arcana'.
中野区/Nakano-ku
オーガスト/August
千代田区/Chiyoda-ku
ブラウニーブラウン/Brownie Brown → ワンナップスタジオ/1-UP Studio
A games company derived from the former Square's Seiken Densetsu/Mana Series team. It became independent in a similar way to Takahashi Tetsuya of Xenogears, and the subsequent treatment is almost identical. Both of them have worked with Nintendo. The company developed Mother 3, but I could never consider Mother 3 to be their masterpiece. Mother 3 is a Itoi Shigesato game from head to foot.

品川区/Shinagawa-ku
SEGA AM11 → SEGA-CS1/龍が如くスタジオ/RYU GA GOTOKU STUDIO
This is not limited to games development, but it seems that people who cause gaffe incidents are always destined to be kicked out of their organisations.
港区/Minato-ku
マイルストーン/MileStone
2013, Kimura Hiroshi, the president of MileStone, was arrested for violations of the Financial Instruments and Exchange Act. There has been no movement at all in this company since 2013, but a sequel to Radirgy is supposedly on the way?
江東区/Kōtō-ku
ノーチラス/Nautilus
2005, Shadow Hearts: From the New World is launched and the development team disbanded.
渋谷区/Shibuya-ku
スキップ/skip
Former Lovedelic staff's company. The company itself is believed to be bankrupt as game development has been suspended since 2015 and the official website has been closed. There will be many more cases like this in the coming years. Only the big companies will survive.
千代田区/Chiyoda-ku
オーバーフロー/Overflow
2012, It ceased to function as a games company. Currently a copyright management company run by the former president. Including âge and Nitroplus above, the company used to be called Chiyo-ren because its head office is in Chiyoda-ku.
港区/MInato-ku
バンダイナムコ/Bandai Namco
2005, Bandai merged with Namco. In name, the two companies appear to be equal, but in substance, Bandai has made Namco a subsidiary. This Gundam One Year War was a shit game developed by Namco and marketed by Bandai. This game was the catalyst for the two companies to merge and become Bandai namco. Was this merger a good thing?

2010 Hiatus
渋谷区/Shibuya-ku
エニックス/ENIX
The company merged with Square in 2003 to become SQUARE ENIX. ENIX was just a publisher, so ENIX itself did not have the capacity to develop games.
台東区/Taitō-ku
タイプムーン/TYPE-MOON
千代田区/Chioda-ku
ニトロプラス/Nitroplus
Urobuchi Gen, who is apparently still the managing director of this company. Maybe the reason I have no interest in this game at all is that it looks like a copycat of what Nitroplus did.
渋谷区/Shibuya-ku
アルファドリーム/ALPHADREAM
2020 Bankrupt. It is surprising that some games companies go under even when working with Nintendo.
品川区/Shinagawa-ku

The president is Kono Hifumi, who was at Human. Famous for its clock tower. There have been no new releases or other developments since 2015.
品川区/Shinagawa-ku
キッド/KID/Kindle Imagine Develop
2006 Bankrupt. CyberFront, which was a brave name in the localisation of foreign games, took over the KID brand, but CyberFront also went bankrupt in 2013 and was dissolved. After that, 5db/MAGES. took over all the copyrights of the KID brand. For me, the only image I have of this company is that they only made visual novels. I also have the impression that their basic technical skills were unnecessarily high even though they only made visual novels.
練馬区/Nerima-ku
ブロッコリー/BROCCOLI
I had forgotten about the very existence of this company until I created this list. At the same time, Galaxy Angel too.
石川県 白山市/Ishikawa-ken Hakusan-shi → 千代田区/Chiyoda-ku
アイレム/IREM
Along with Treasure and Sandlot, this is probably the games company that deep gamers prefer. I think it's amazing that it still survives so tenaciously.
目黒区/Meguro-ku

Former Lovedelic staff's company.
品川区/Shinagawa-ku
セガ/SEGA
I attribute Sega's loss to its inability to attract Enix and Square at the time to Sega hardware. (This list may be one piece of evidence to support this.) No matter how many good games Sega itself mass-produced, it would lose. Sega's shining form was like looking at a former Deutschland that could not build alliances. In researching things about Sega when compiling this list, I was convinced that "Sega is Germany". There's no good that can come from such a dispersal of development resources! Sega, you idiot! I don't know any more! Comparing this, this and this, I can finally get a fuller picture of Sega's game development system. Knowing that SEGAGAGA was a true and honest portrayal of the inner workings of SEGA was perhaps the best part of compiling this list. AM development rooms below, in numerical order.

Pretty sure you are competing with @lpslucasps to see who can create more huge lists in less time. lol

I won't make a list this big again! lol
I'm so tired... (私、疲れちゃったよ...)

news to me that the original project diva had a co-developer! I've only played that one a couple of times

The use of linking to other lists is cool, but ruined by the fact this site logs me out every time I use them.

@Vee Should I remove links to other lists?

Do I get logged out because I enter https in the link address? I have removed https from the link. If this does not work, I will remove it.

@Pangburn I only knew Dingo from Photokano, but it's a shame it went bankrupt.
Oh yes, I forgot to thank you. Your Famitsu list was helpful, thank you very much.

I personally do not get logged out when clicking on a link to another list but I've heard of others having the problem; suffice to say it's a site issue, and not particular to this list @LSW. also no worries!! all i did was copy some shit i saw online lol, you've done so much more work cataloging so many developers

1 year ago

Yeah, I wouldn't worry about changing the links. It's an odd issue that seems to happen at random for certain users, it was just frustrating for me this instance.
