荒馬
It's been ages since I had Oshichi—wow, seriously delicious! By the way, next to the herring roe is kabura sushi. It's a fermented food made by sandwiching salted yellowtail or mackerel between layers of turnips and pickling it with rice koji. You might only find it in the Hokuriku region. This was made at my parents' house, but it's perfect with hot sake!
