Tokyo: enterprise transformation and frontier hardware

Tokyo is a different kind of AI market. It mixes world-class research, with Preferred Networks doing deep learning work for manufacturing and robotics, a massive enterprise layer where SoftBank, Rakuten, Mitsubishi, NTT Data and the megabanks drive serious AI budgets, and a gaming and entertainment industry that has been quietly weaving generative AI into its pipelines. Stability AI Japan, Sakana AI, ELYZA and the Japan AI Safety Institute signal a growing local frontier model scene, while Shibuya and Roppongi host a startup ecosystem now maturing into Series B territory.

Tokyo projects reward long-term relationships, quality code and careful attention to Japanese-language and cultural requirements.
