Naoko Miura, founder · New York pop-up

It began with a thought from founder Naoko Miura, a former hula-event producer: in the endless summer of Hawaii, chilled noodles could be enjoyed the whole year through.

Hawaii proved out of reach, so she took the idea to New York: three summers of pop-ups from 2016. In 2019 the concept crossed back to Japan, opening first in Akasaka. After Akasaka and a shared kitchen in Kichijoji, HiyaChu opened its first home of its own in Nishiogikubo on 27 July 2023.

“Do what doesn’t exist yet.”
A specialist that serves only chilled ramen, twelve months a year. There has never been one before.
