The tuna we received this time was wild-caught in the waters near Hobart, Tasmania. We were told that these fish weighed approximately 60–120 kilograms each.
The fact that tuna of this size can grow naturally and be caught in Tasmanian waters is something we find truly remarkable. It gives us a deep appreciation for the richness of the natural environment here.
For many Japanese people, tuna is perhaps the most beloved of all sushi toppings.
Honmaguro (本マグロ), or Pacific bluefin tuna, has its own distinctive appeal. Yet we find that tuna grown in Tasmanian waters has a different character and deliciousness of its own.
For this particular tuna, we wanted to create something that could stand alongside its powerful umami. Using several varieties of koji that we have cultivated ourselves, we prepared our own original shoyu koji blend, a fermented seasoning made with soy sauce and koji.
These include our homemade barley koji, black koji, white rice koji and buckwheat (soba) koji. We blended together the shoyu koji prepared using each of these different koji.
The resulting shoyu koji blend has the depth and strength to complement the rich umami of the tuna, while bringing together the deeper umami developed through koji fermentation, the individual characteristics of each grain, subtle acidity and complex layers of flavour.
We would love for you to experience this alongside sashimi made from wild Tasmanian tuna.

With thanks to for this extraordinary tuna.
