This project is part of the event "Discovered in the shopping district! Surprised JJJ" that Arakawa Ward and Taito Ward have been holding since October. The Ameyoko Center Building, which is also the location of "Ama-chan", is a prize exchange for the "Stamp Rally JJJ!" Event, which is held from November 1st to November 10th in the shopping districts of both wards. It seems that he was chosen.

The exchange will be on the 5th floor of the same building. Under the title of "Amachan Cafe Corner", there are a sea maiden cafe set, a Tokyo EDO theater corner, a Minami-Rias Railway commemorative photo corner, etc., and you can enjoy it with a simple drink such as coffee. The stamp rally prizes include "Amachan-related goods" such as "Amachan T-shirts" and "Amachan Tenugui".
