Is This Osaka’s Best Value Omakase? 15 Pieces for ¥4,400 at Sushi Koshin
In the world of high-end sushi, the word “Omakase” usually prepares your wallet for a significant hit, often starting at ¥15,000 and climbing rapidly. But tucked away on the 3rd floor of a building in Higashi-Shinsaibashi, a young chef is turning the industry on its head.
Sushi Koshin (鮨 滉心) offers a full 15 course experience for just ¥4,400 (tax incl.). Here is why you need to book a seat before the rest of the world finds out.
The Chef: Passion Over Pretense
The restaurant is helmed by a 23 year old chef who sharpened his skills at Michelin listed establishments. His mission? To make authentic Edomae sushi accessible to everyone, not just those with corporate expense accounts. The energy in the room is vibrant, centered around a sleek C-shaped wooden counter where you can watch every slice and press of the nigiri.
The Course: What You Get for ¥4,400
The “Koshin Omakase Course” isn’t just a few pieces of fish; it’s a choreographed 15 item journey. While the menu changes daily based on the market, a typical session looks like this:
The Starters: Often begins with a rich Suppon (soft-shell turtle) soup or a delicate appetizer like Zuwai crab with crab-miso butter.
The Nigiri (8–10 pieces): Expect high-quality cuts like Akami (lean tuna), Chutoro (medium fatty tuna), Kinmedai(Splendid Alfonsino) with a light sear, and buttery Anago (sea eel).
The Signature Finish: This is the restaurant’s “X-factor.” The meal concludes with Authentic Seafood Broth Ramen. The broth is made from the day’s fish bones and trimmings, and, here is the kicker, the ramen is all-you-can-eat.
The “Koshin” Experience
Despite the low price, the attention to detail is remarkable. The sushi rice (shari) is seasoned with a custom blend of vinegar to complement the fish, and the garnishes, like homemade ponzu or kelp-infused sauces, feel premium.
Pro Tip: The restaurant operates on a strict two-seating reservation system. It is highly recommended to book via TableCheck or Instagram well in advance, as seats fill up weeks ahead.
