KIWA Corporation opens Tsubakitchen, a 20-seat pop-up restaurant in Shibuya, on November 20

KIWA Corporation (際コーポレーション) will open a new restaurant called Tsubakitchen (ツバキッチン) in Shibuya on November 20, according to the Tokyo restaurant and hospitality group's own announcement. The 20-seat shop sits at 2-8-11 Shibuya, Shibuya-ku, near Shibuya and Omotesando train stations, and runs on cashless payment only, the company said.

Tsubakitchen will be open from 11:30am to 7pm, closed Mondays and Tuesdays, KIWA said; the announcement bills it as a pop-up restaurant and discloses no concept, menu, prices or closing date beyond the opening date, address and seat count. The shop page styles it KAMIGOTO TSUBAKITCHEN. On its company page, KIWA lists 267 restaurants it runs directly, alongside 13 shops, 13 franchise outlets, 20 affiliate-run stores and five lodgings.

A 20-seat pop-up on a Shibuya side street is a small bet for a group with 267 directly run restaurants, but a familiar one: KIWA runs its portfolio as a string of small, swappable concepts rather than scaling any single brand wide, and a pop-up lets it test an idea on a prime street without committing to a long lease. Whether Tsubakitchen graduates into a permanent concept, or simply closes when its run ends, is something this announcement doesn't say.
