The shop's own daily opening posts on X (@1minutes_akiba) state 13:00-19:00, and its profile gives the same 13:00-19:00 buyback window. That is two hours later than the 11:00-19:00 floor hours the mall operator announced for the 5F Toreca Mall, so this counter alone is shut in the morning.
One to two minutes south of the JR Electric Town Exit along Chuo-dori, in the blue building on the Manseibashi crossing (EDION AKIBA / Laox Akihabara Main Store). Take the Laox-side elevator - not the electronics entrance - to 5F; the counter is inside the Toreca Mall floor.
Tips
A buyback-first counter selling itself on appraisals in as little as one minute and full cash payouts - handy when you want to offload quickly.
It advertises strengthened buying of singles and PSA-graded cards; the buy list lives on a separate account, @toreka_kanpai.
It opens at 13:00, two hours after the rest of the floor, and everything closes at 19:00, so plan selling trips for the afternoon.
Whether it sells anything over the counter is not stated anywhere public; for buying, use the other Toreca Mall shops on this floor and in the basement.
