Common Fish and Marine Mammals in Japanese

Tuna holds a special place in Japanese cuisine, particularly in sushi and sashimi. The most prized part, the fatty belly portion called 大トロ (ō-toro), can command impressive prices at Tokyo’s famous Tsukiji and Toyosu fish markets.
Example sentence: 「今日の夕食はマグロの刺身です。」 Kyō no yūshoku wa maguro no sashimi desu. “Today’s dinner is tuna sashimi.”
サケ (Sake) – Salmon
While “sake” is also the word for rice wine in Japanese, context makes it clear when referring to this popular fish. Salmon is widely enjoyed in Japan, whether raw in sushi or grilled with salt.
Example sentence: 「サケは栄養価が高い魚です。」 Sake wa eiyōka ga takai sakana desu. “Salmon is a fish with high nutritional value.”
タコ (Tako) – Octopus
The octopus is highly regarded in Japanese cuisine and culture. This intelligent creature appears in dishes like takoyaki (たこ焼き), popular street food consisting of battered octopus balls topped with special sauce.

イカ (Ika) – Squid
Squid is a versatile ingredient in Japanese cooking, appearing in dishes from sashimi to tempura. Its clean, mild flavor makes it a popular seafood choice throughout Japan.
Example sentence: 「イカの刺身は新鮮な方が美味しいです。」 Ika no sashimi wa shinsen na hō ga oishii desu. “Squid sashimi tastes better when it’s fresh.”
サメ (Same) – Shark
While not as commonly eaten as other seafood in modern Japan, sharks play an important role in Japanese marine ecology. Some species, like the whale shark, can be seen in Japan’s larger aquariums.

Example sentence: 「北海道のホタテは特に美味しいと言われています。」 Hokkaidō no hotate wa toku ni oishii to iwareteimasu. “Hokkaido scallops are said to be especially delicious.”
