Chonbokun, Yokohama’s Smoke-Free Mahjong Parlor

Field notes

The page distinguishes free play from set play, with staff guidance available for solo or first-time visitors and phone reservations for groups. Its rules section specifies a 25,000-point starting score, 30,000-point return, 1,000/3,000 uma, three red fives, and 500-point bonuses. The venue is above the yakitori restaurant “Bankichi,” and the site explicitly permits customers to bring takeaway food upstairs.
