The world of authentic Japanese eating can seem shrouded in mystery. Between the omakase mystery fish and your fear of accidentally eating blowfish, you too often resort to tuna maki.

Not at Douzo, you won’t. Back Bay’s brand new sushi house, brought to you by Jack Huang (one of the forces behind Fugakyu) is as accessible as they come. (Douzo even means “go ahead” in Japanese.)

The room — 4,000 square feet of high ceilings, sleek mahogany, and breezy swaths of fabric — is unusually handsome. Grab a seat in the sunken dining room and order a sake flight or a lychee martini, then dig into the kitchen’s feather-light veggie tempura and crispy salmon spring rolls.

And don’t be shy when it comes to the sushi bar. Ask for super-fresh sashimi like chutoro (fatty tuna) and sea urchin. Down them all, then wonder how they manage to taste so straight-from-the-sea.

Now that’s our kind of mystery.

Douzo, 131 Dartmouth Street, Back Bay (617-859-8886).
