Local foods and products in Izu and Ogasawara Islands


It is the sushi served in Izu and Ogasawara Islands. Hachijojima island is the central place of it.
These area is warm, so the fish topped on vinegared rice is used after being marinated in shoyu (soy sauce) before fish goes bad.
And because "wasabi" had been unobtainable, mustard is used as the spice instead.


It is a dried fish produced in Izu Islands.
But it emits a disgustful smell when it is grilled. (When a person grilled it in a city, he had been reported to the police that someone was burning a "dead body".)
It is made by washing fresh fish in clear water, soaking in "kusaya brine" for a day and drying in the sunshine.
The "kusaya brine" is the criminal of smell. It is the brine with fermented ingredient of fish for many decades.

Camellia oilCamellia oil

Camellia japonica is the native flower of Japan, which is distributed throughout the country except Hokkaido. Especially Izu-Ooshima island is known for the camellia.
In Japan, camellia oil has been used as hair dressing since old times.
It is made from camellia flower seeds. But because the seeds are gathered once a year, the amount of production is not so much.
In Izu Islands, half of Japan's camellia oil is produced.
