Akihabara. Where things get built.
Technology & building: Electric Town, Radio Kaikan’s hardware, AI builders on Chūō-dōri and indie hackers under the Manseibashi arches.
The story of Akihabara
Akihabara began as a black market for radio parts and became Electric Town: the place where Tokyo came to buy, solder and tinker. Its multi-storey electronics buildings still sell components by the gram, and its side streets are full of people making things.
In CollaboTokyo, Akihabara is home to builders: AI and agent developers on Chūō-dōri, hardware and robotics at Radio Kaikan, indie hackers under the Manseibashi arches, and open-source contributors in Suehirochō.
Builders come here to find each other — and to find the creators who will explain what they’ve built to the world. Post a beta at the station stall and see who walks up.
