Kahoshi City (かほし市 Kahoushi-shi) is a fictional location in Japan's Saitama prefecture, and is where the majority of Heirloom Star takes place. It is where Yumemi, Tomomi, Kenichi and Megumi live.


  • Kahoshi's name is a pun on the series' title, which literally is a portmanteau of kahō (かほう/家宝 heirloom) and hoshi (ほし/星 star). Thus, the city's translated name would be Heirloom Star City.
