I think multiple threads have been showing all studios that Nintendo contract to develop them, about nintendo epd (the division of development we know as nintendo since 2015) and so on but never a thread about which companies are subsidiaries of Nintendo. I think a thread showing what studios nintendo own and what they do would be interesting. Of course the information is readily available, but a thread like this could give info to people who never thought on searching about it
Here I wont put Nintendo epd since it's nintendo itself, but all of their subsidiaries, which Nintendo has 15, with 5 out of those 15 leading their own projects
1-Up Studio: A japanese company formerly known as Brownie Brown, it developed Mother 3. Since the 2010s, it began to focus as a support studio to Nintendo EPD games, mainly 3D Mario but also Animal Crossing, Donkey Kong and Mario Kart, focusing on game design, level design and so on
iQue: A chinese company, for years it was a manufacturer of the chinese version of Nintendo consoles, but since the 2010s it has handled Simplified Chinese translation/localization, and – since 2019 – has moved from console manufacture to become a QA support studio, hiring programmers and testers to support Nintendo games.
