Our Japanese Horse Mackerel (Aji) Fillets are sourced from Japan and prepared in a traditional sushi style, with the skin largely scraped and removed prior to packing. Because aji is a naturally small fish, further skin removal is often not possible without compromising the fillet—this preparation is intentional and designed for immediate use.

Aji is valued in Japanese cuisine for its clean, lightly oily flavor and delicate texture. Unlike heavier mackerel species, it is refreshing and balanced, making it ideal for sashimi, nigiri, or simple raw preparations.

These fillets are intended to be enjoyed as-is, requiring little to no additional prep beyond slicing. When freshness is respected, aji delivers one of the purest expressions of everyday sushi.

Why Japanese Aji?

Japanese aji is prized because it is:

Naturally small and delicate

Prepared specifically for sushi consumption

Mild and clean, not overly oily

Best enjoyed fresh and simply

In traditional Edomae sushi, aji is a test of both sourcing and handling.

How to Enjoy

Slice gently for sashimi or nigiri

Serve chilled with minimal seasoning

Excellent with ginger, scallion, or citrus

Heavy cooking or aggressive seasoning is not recommended.
