What is it?
Shimonoseki tsubu uni preserves sea-urchin roe with salt and alcohol while keeping visible pieces, then packs it in small jars. It is a concentrated processed specialty eaten by the teaspoon, not a general page about raw uni bowls and sushi.
Shimonoseki calls itself the birthplace of bottled uni. A city-transmitted story says gin spilled into uni at Saikyoji temple on Mutsurejima in the early Meiji period, inspiring the alcohol-preserved form; this remains an origin tradition rather than a fully documented accident.
History and local context
Tsubu uni keeps pieces more intact than neri uni. Species, uni percentage, salt, alcohol, coloring and storage vary and should be compared on each label.
The regional marks Shimonoseki Uni and Kitaura Uni cover processed uni made in defined areas. They do not by themselves guarantee that every raw urchin was harvested locally.
How to enjoy it
Start with a rice-grain-sized amount on plain rice, then try it in an onigiri, with squid or fish cake, or stirred into pasta off the heat.
Refrigerate opened jars as labeled and use a clean dry spoon. Check alcohol, salt and allergy considerations.
Availability varies by maker, season, and destination.
