american diner culture, rooted in the heart of Hitachinaka.
Real smash burgers. Good music. Always welcoming.

Our Story
Born from a love of California diner culture, 33 Diner brings that spirit to the heart of Hitachinaka.
Our name comes from "33 Street" (Showa Street) — the beloved main street that runs through our community. We're operated by Sekiyama Gakki, a local family business with over 70 years of history rooted in music and community.
More than great food, we're here to create moments of joy — through good music, warm conversation, and carefully crafted dishes made with ingredients we're proud of.
We can't wait to become a place this community loves for generations to come.

THE WAFFLE

THE milkSHAKE
Made thick. The way it should be.

Delivery
