Known for fiery Sichuan-style mapo tofu, dan-dan noodles, and dumplings with a distinctly spicier profile than most Chinatown restaurants. Popular with locals who want a different take on Yokohama Chinese food.
Heiko-ken is a standout restaurant in Yokohama Chinatown's predominantly Cantonese landscape — a kitchen that focuses on Sichuan cooking, offering the fiery, numbing, and deeply aromatic flavour profiles associated with China's most internationally celebrated regional cuisine. Located at 186 Yamashitacho in Naka-ku, Heiko-ken draws a clientele that specifically seeks the mala (numbing spice) intensity of authentic Sichuan preparation, which distinguishes it from the milder Cantonese cooking of neighbouring Chinatown establishments. The mapo tofu at Heiko-ken is one of the best preparations of this dish in the Yokohama area: silken tofu cubes suspended in a deep red sauce of fermented black bean paste (doubanjiang), Sichuan pepper, minced pork, and chili oil, with a mouth-numbing heat that builds gradually and lingers pleasurably. Dan-dan noodles (Tantanmen in Japanese) arrive with a complex base of sesame paste, black vinegar, chili oil, and minced pork over thin wheat noodles — a dish that has developed its own Japanese adaptation but is here prepared closer to its Chengdu original. Spicy wontons in chili oil (hong you chao shou) are served as a starter and showcase the clean heat that distinguishes good Sichuan cooking from merely spicy food. The restaurant is particularly popular with local Yokohama residents who want a bolder, more pungent experience than the Chinatown mainstream offers, and dinner reservations on weekends are recommended. The dining room is mid-sized and informal, with simple decor that puts attention firmly on the food.

Tips for visiting
- Order the mapo tofu and dan-dan noodles as a pair — they represent the Sichuan kitchen at its most distinctive.
- Sichuan pepper (hua jiao) produces a numbing sensation rather than burning heat — mention to staff if this is unwanted.
- The spicy wontons in chili oil work well as a shared starter before the main courses arrive.
- Closed Wednesdays — factor this into a Chinatown visit.
- The level of spice can be adjusted on request; the default preparation is moderate-to-hot by Japanese standards.
Accessibility
Heiko-ken is at street level in Yamashitacho with a standard entrance step from the Chinatown pedestrian lane. Interior seating is at standard table height with chairs. The dining room is not particularly large; navigating with a wheelchair during busy service hours may be challenging.
Frequently asked questions
How does Sichuan food differ from the Cantonese cooking of other Yokohama Chinatown restaurants?
Cantonese cooking (the dominant Chinatown style) emphasises clean flavours, fresh ingredients, and light seasoning. Sichuan cooking is characterised by mala (numbing and spicy) flavours derived from doubanjiang (fermented chili bean paste) and Sichuan peppercorns, which create a distinctly different flavour and physical sensation.
Is the food very spicy?
By Japanese standards, Heiko-ken's Sichuan dishes are significantly spicier than most Chinatown options. The mapo tofu and dan-dan noodles carry genuine heat. Spice level can be reduced on request, but the restaurant is primarily aimed at diners who enjoy authentic Sichuan intensity.
Are reservations required?
Reservations are recommended for dinner, particularly on Friday and Saturday evenings. Lunch on weekdays is generally walk-in. Reserve by calling the restaurant directly.
Does Heiko-ken offer dishes beyond Sichuan?
The restaurant's strength and focus is Sichuan cooking. A small number of standard Chinese dishes are available for diners seeking less spicy options, but the kitchen is best represented by its Sichuan specialties.
