A building of hobby, figure, card and doll shops in front of Akihabara Station. In Steins;Gate, Okabe visits a press conference hall inside it, and the building has run official collaborations with the series, most recently for Steins;Gate RE:BOOT. in summer 2026 (now ended). Building hours are roughly 10:00–20:00; each shop sets its own.

Please be a considerate guest: keep your voice down, keep paths clear and leave the place as you found it.
