On a walking distance from Tanimachi line’s Tanimachi-9-chome Station is Mitomi, a tiny little café/shop that sells delicious and fancy Monakas.
The shop is located in a residential area, in what seems a garage sized space renovated into a small shop. When the shop is closed the shutter goes down, completely hiding it, hence it might be a little hard to find if you arrive before opening time.
Once the shop is open, a stylish, modern Japanese exterior appears, complete with noren (curtains at the entrance of a shop).
