About
Yaichi opened in late 2025 in Milpitas' Ulferts Center, introduced by the same Tokyo-raised chef-owner behind Leichi (Santa Clara) and Kaita (San Jose Japantown). Chef Nobu Kashima's concept here focuses on kaisendon — the seasonal seafood rice-bowl format beloved across Japan in fish markets, beachside restaurants, and izakayas, but still rare in the Bay Area. Three bowl tiers range from the Ume (yellowfin tuna, flying fish roe, scallops, snow crab) to a premium version with Hokkaido sea urchin. The rice is plain and unseasoned in the Japanese style, meant to be eaten rolled into dried nori hand-rolls and finished with a poured ochazuke (dashi) at the end. Handmade Sanuki-style udon, prepared on a noodle machine imported directly from Japan and producing remarkably chewy noodles in a sardine-rich broth, completes the menu. KQED's coverage in February 2026 cemented Yaichi as one of the most talked-about new Japanese openings in Silicon Valley.
Why it's on Washoku Guide
  • Kaisendon — the seasonal seafood rice-bowl tradition straight from Tokyo's fish markets — is nearly impossible to find executed at this level outside Japan.
  • Handmade Sanuki-style udon prepared on a machine imported from Japan delivers a texture and sardine-dashi broth depth that sets a new standard for udon in the South Bay.
  • The interactive kaisendon eating format — rolling rice into nori, mixing wasabi, finishing with poured dashi — makes every bowl both a meal and a mini-lesson in Japanese food culture.
  • The third restaurant from chef Nobu Kashima's growing family of authentic Japanese concepts, each exploring a different dimension of Japanese cuisine with rigorous sourcing.

Closed Tuesdays. No reservations — walk-in only. KQED (2026) recommends arriving close to opening time as bowls and noodles have limited daily quantities. — Format: Casual dining. Authenticity: Tokyo-raised chef-owner Nobu Kashima (also of Leichi and Kaita) brings kaisendon — the Japanese seafood-bowl tradition from Tsukiji and Japanese beachside restaurants — to Milpitas, with fresh handmade udon made on a machine imported from Japan and Sanuki-style noodles with sardine-dashi broth.
