Shimaaji Arrives — Big, Fatty,
and Best Served Aburi-Style.

Sashimi DC — September 9, 2026 update

Storms moved through central and eastern Japan this week, disrupting fishing activity and tightening the market — prices are up and volume is down across the board. Against that backdrop, we were glad to land a strong batch of Shimaaji (striped jack), each fish running around 1.8kg — noticeably larger than what we usually see.

This Week's Star: Shimaaji

Shimaaji is traditionally thought of as a summer fish — its shun, or peak season, is said to fall around now. But like many species, it keeps adding fat as it heads toward its winter spawning season, so the flavor only gets richer from here. September sits right in between: the fish still has summer's brightness, with the first extra fat of the season starting to show. At ~1.8kg each, this week's fish are well above average size, which means a thicker fat layer to work with.

Why We're Serving It Aburi-Style

Aburi means lightly torching the surface of a cut of fish rather than cooking it through. Shimaaji carries a thin layer of fat just under the skin, and running a flame briefly over that layer renders it and releases an aroma that raw preparation alone doesn't bring out. It's one of Keita's favorite ways to serve this fish — the skin side gets a light char, the fat underneath melts slightly, and the aromatic lift makes the difference. Come by and ask us to prep it Aburi-style at the counter.

Sasshu Salmon Returns September 16

Our Sasshu Salmon imports have been paused and resume on September 16. This week's case does not include it — expect it back in the usual rotation next week.

Common Questions About This Week's Fish

What is Shimaaji?

Shimaaji, or striped jack, is a member of the jack family closely related to Kanpachi and Hamachi. It's prized for a firmer bite than most jacks and a clean, slightly nutty flavor. This week's fish are unusually large at about 1.8kg each, well above the typical size we see.

Why is September a good time for Shimaaji?

Shimaaji is traditionally considered a summer fish (its shun, or peak season), but it keeps building fat as it approaches its winter spawning season. September sits in between — the fish still carries summer's brightness while starting to pick up the extra fat that makes winter Shimaaji so rich.

What is Aburi and why try it with Shimaaji?

Aburi means lightly torching the surface of a cut of fish rather than cooking it through. Shimaaji carries a thin fat layer just under the skin, and torching that layer renders it and releases an aroma that raw preparation doesn't bring out — it's Keita's preferred way to serve this fish.

Why are seafood prices higher this week?

Storms moved through central and eastern Japan this week, disrupting fishing activity and tightening supply at the source. Less fish reaching the market pushed prices up broadly, not just for the items we carry.

When is Sasshu Salmon back?

Sasshu Salmon imports resume September 16. This week's case does not include it.

Is the September 20 Knife Sharpening and Sashimi Slicing Class still available?

Yes. The September 13 and September 27 classes are both sold out, but tickets for a newly added September 20 class are available now on shop.sashimidc.com.
