Yokosuka Tsunami Sangsuan aged-sashimi izakaya with a line before opening, the daily menu is the real draw

The "menu of the day" is the real reason to come

Seasonal sashimi rotates in and out, and there are standing items like the assorted sashimi platter, but what you're really here for is the "menu of the day," posted on Instagram (@yokosuka_tsunami).

This place is clearly good at what it does — getting in is the hard part. You need to line up before opening most days.

The aging is what makes the texture

What makes this place is the aging. The sashimi here is aged particularly well, so it has a chewy, almost sticky texture that clings to your palate — noticeably different from the usual sashimi.

What it looks like on the plate

White-fleshed and red-fleshed fish share one octagonal plate, with wasabi, daikon sprouts and sliced green onion. A few pieces still have their skin on, and the red slices have a gloss. A dish of soy sauce sits apart, and a ceramic sake bottle painted with waves stands next to the plate. What you get depends on what came in that day.

Menu words

• Sashimi is raw fish sliced thin. Modum-sashimi is an assortment of several kinds on one plate
• Sukseong-hoe is raw fish that has been rested for a period after catching to deepen its flavor and texture
• Because the menu changes daily, ask the staff "Oneul mwoga joayo?" (오늘 뭐가 좋아요?)

The wait, and notes for visitors

I think about this place from time to time, but the wait keeps me from going often. You need to arrive before opening to get a table. Going with low expectations about the wait is good for your sanity. If you have time to kill in line, Roofcatme Cat Cafe, Hongdae is a short detour in the same Hongdae area.

• If you enjoy raw fish, this suits you well. The aging gives it a noticeably chewier texture than typical sashimi
• The menu changes every day. There's no fixed board, so just ask the staff what's good today
• Soy sauce and wasabi are the standard condiments, so nothing here will feel unfamiliar — it's a sushi/sashimi spot foreign visitors can enjoy too
• Expect to queue. Arriving before opening is the safe move

Good for you if

• ✅ You like the chewy texture of well-aged sashimi
• ✅ You want to try whatever seasonal fish is on that day
• ✅ You can handle waiting before opening
• ⚠️ You want to walk straight in with no wait — look elsewhere
• ⚠️ You prefer ordering off a fixed menu — here you ask what's available that day
