This Kaisen-don (assorted raw fish on rice) is from Shimanokaisendonya.
The shop is inside Shimanoshiki which is a local produce market in Itoshima.
When I first moved to Fukuoka, I was surprised Kaisen-don here is often not colorful.
It because they use local fish.
And it is just caught so it is fresh and good.
And often people in Fukuoka use sesame soy sauce.
The miso soup at this restaurant, which contains the bony part of a fish, is also good.
