Building hours

The building keeps no common hours. Shinsoku's Akihabara buyback centre on 1F is a buy-only counter open 11:30-19:30, with the last items taken at 19:00. CrownTiara on 3F runs 17:00-23:00 Mon-Thu, from 17:00 on Friday and from 12:00 on Saturday through to 05:00 the next morning, and 12:00-23:00 on Sunday and public holidays, making it the latest-opening tenant. Holocard on 6F changed its hours in August 2026 and now opens 12:00-20:00 on weekdays and 11:00-21:00 at weekends and public holidays. There is only one lift.

Getting there

Four minutes from Suehirocho Station on the Ginza line, eight from the JR Akihabara Electric Town Exit. It is a seven-storey office building from 1981 on Shohei-bashi-dori, one block west of Chuo-dori. Shinsoku's trading-card buyback counter holds the ground-floor frontage; the shared entrance is the narrow doorway beside it and the building's single lift serves the upper floors. There is far less signage here than on Chuo-dori, so use the Shinsoku shopfront as your marker.
