Who We Are

Kaisen Ichi simply means “Seafood One”.

Harmonising the freshest imported (seafood) ingredients / prime cuts into (one) bowl, Kaisen Ichi creates quality lunch bowls for the discerning lunch crowd looking for fuss-free, healthy and comfort food to fuel up for the day. Adorned with generous portions of premium ingredients atop a bed of Aomori Masshigura Japanese rice, the umami flavours of our selection of donburis will be sure to satisfy any palate or craving of the day.

The food menu is expanded during dinner to include a wide range of yakitori and grilled dishes to complement our sake, beer and whisky.

The Big Three


Our whole day dining menu features one of our diners’ favourite – Kaisen Bara Chirashi Don – which blends an abundance of premium quality sashimi with seasoned Japanese sushi rice. Our Donburi selection includes rice bowls with unagi, beef, pork & chicken etc.

Chazuke (Green Tea Soup)

Our Chazuke dishes are the first of its kind in Singapore where we put a new twist on a century old Japanese dish! Enjoy our healthy green-tea soup and rice together in harmony with carefully selected ingredients such as unagi, salmon, chicken or prawn.

Inaniwa Udon

The third style of dishes available are the Japanese hand-stretched udon from Akita prefecture in Japan. These noodles are hand kneaded multiple times to give the soft and chewy texture that is distinctive in traditional udon. The dishes are also paired with Japanese style hanjuku egg with firm whites and soft yolks.
