Tenkin
Founded 1961. Rare among Kumamoto ramen shops for its non-cloudy, clear-style tonkotsu broth. Incredibly priced from 600 yen. Just one 4-person table and 5 counter seats, yet always full at lunchtime.
Reviewers praise the light, non-cloudy tonkotsu as easy on the stomach. '600 yen is the best value in Hitoyoshi.' Tabelog 87 reviews. The unchanged taste since 1961 makes it a quiet local staple.
