Tama-ya (たまや Tamaya) is a rice cake (mochi) shop ran by the Kitashirakawa Family in the Usagiyama Shopping District. It is located directly across from another rice cake shop, Ōji-ya. It is also the home of the Kitashirakawa family, and was temporarily lived at by Dera Mochimazzi.
It is said to have been established because Fuku Kitashirakawa's grandfather had owned a mochi shop. Its successor became Mamedai, and is planned to be Tamako for her future plans following graduation. Due to Mamedai's traditional ways, it also tends to be traditional in its mochi baking and is considered less modern than its rival Ōji-ya.
- The model for Tama-ya is based off on a store in Demachiyanagi Shopping Street.
