Which is the most authentic Japanese restaurant in Kunshan? Where is it?

There are two kinds of authentic Japanese food I have eaten. One is Rhine Square and Osaka cuisine at the junction of Zhenchuan Road and Bailu Road.

The other one is at the junction of Qianjin Road and Heilongjiang Road, north of Junhao Hotel, and arranges Japanese cuisine.

Among them, Osaka cuisine is more expensive than Lin because of its geographical location. The Japanese who have dinner with me all think that the sashimi cooked by Lin Japanese cuisine is the most authentic and delicious in Kunshan. Osaka cuisine is more suitable for people with a large number of people, because there are many boxes inside, and Japanese cuisine tastes good. Above, please adopt, thank you!
