What is it?
Shima-zushi from Hachijojima marinates nearby fish in a soy-based sauce, places it on slightly sweet sushi rice and uses Japanese mustard instead of wasabi. Savory fish, sweet rice and sharp mustard meet in one bite.
There is no single fixed fish. Flying fish, Japanese butterfish, striped jack and other seasonal catches are used, and seaweed may also be formed as sushi. Tokyo sources trace the style from Hachijojima to other Izu and Ogasawara islands and to Daito in Okinawa.
History and local context
Hachijojima Tourism describes soy marination as a way fish was kept on trips offshore. Today it is valued for flavor as well as preservation and appears in sushi shops, restaurants and island supermarkets.
Mustard is often explained by the former difficulty of obtaining wasabi on the warm island, but the precise history is not settled. Island variations also include green-chili soy sauce, so one explanation should not erase local differences.
How to enjoy it
Because the topping is already marinated, eat the first piece without extra soy sauce and note the hidden mustard. Ask which fish was landed that day and compare its texture with the sweet rice.
This is raw-fish sushi: keep takeaway chilled, minimize carrying time and eat it promptly. Travelers with medical reasons to avoid raw seafood should follow professional guidance.
Availability varies by maker, season, and destination.
