*****Original Chawanmushi YOSSOU (Hamamachi Main Branch)

"In my 3 week holiday all around Japan, this restaurant was my favourite and I don’t say that lightly. For me, this was the ultimate authentic Japanese dining experience. I went to other restaurants that were more expensive than this and didn’t come close to this in terms of authenticity and dining.

Word of warning, the staff here don’t speak much English but that’s ok cause you order from a tablet that has pictures on it. Also shoes off is compulsory.

I ordered the 吉宗定食 set for ¥2750 which is great value. All the dishes were spectacular, but the star of the show without question is the chawanmushi. There’s so much filling that goes in it from seafood and chicken. So good I ended up ordering a second. The drinks menu is also excellent with a wide range of choices but I recommend pairing it with some warm sake.

This is a must do when in Nagasaki. Best dining experience I had in Japan."

"Yossou is a gem tucked conveniently within a shopping street in Nagasaki. The ambiance is lovely—calm and traditional—with a charming, rustic exterior that makes you feel like you’re stepping into a piece of history.

The menu offers a good variety, and I went with the sashimi set meal. The sashimi was fresh and satisfying, with just the right portion size. But the true standout was the chawanmushi—hands down the best I’ve ever had. It was delicate, silky, and deeply flavorful, with chunks of chicken, seafood, and mushroom hidden inside that added layers of umami to every spoonful.

Only after my visit did I learn that chawanmushi originated in Nagasaki, which explains why this version was several notches above any I’ve tried elsewhere.

A fantastic dining experience all around—well worth a visit if you’re in Nagasaki."

""This place blew us away! Best chawanmushi ever!"

We arrived around 4pm and were seated right away, which was great. We came specifically for their famous chawanmushi and it was even better than we expected! It was incredibly silky and smooth, like velvet! It seriously just melted in my mouth. The flavor was so delicate and perfectly seasoned. And can we talk about the size of that bowl?! It was enormous and could have easily been a meal in itself. We also ordered the tempura and sushi set, and it was a fantastic choice. The tempura was light and crispy, not greasy at all, and the sushi was super fresh. Honestly, every single thing we ate was delicious.

The restaurant itself has a really nice, traditional atmosphere, and the staff were all very friendly and helpful. Highly recommend this place to anyone visiting Nagasaki!"
