カツオ (Katsuo) Bonito
Sushi tactics fish
Fish move northward and southward annually. Middle of Honshu (the mainland of Japan) in May, north of Sanriku (north east part) and south of Hokkaido in around August and September, and then start moving southward.
The best season is April and May known as 「初カツオ (Hatsu-Katsuo)」,which literally means first in-season bonito in a year, and between middle of August and the late in September known as 「戻りカツオ (Modori-Katsuo)」which literally means returned bonito.
