The Verdict
Nakanoshima is Osaka's river island — a long, narrow sandbar between the Dojima and Tosabori rivers, crowned by the City Hall and the Central Public Hall, ringed by water on both flanks. It is the most European stretch of Osaka, and the location Seiji Nakano chose when he opened Rooots Nakanoshima in July 2024 after a six-month trial period.
Head chef Kenta Kakihara has one of the most serious European CVs of any chef cooking in Osaka. He spent eleven years in Italy, rising to head chef at Duomo Ragusa — one of the two-starred Michelin rooms of Sicily — and then as sous-chef at the one-starred Agli Amici Rovinj on the Croatian Istrian coast. He returned to Japan fluent in two traditions. Rooots places Italian cooking at the base, layers French finishing technique across it, and anchors the whole thing in Kansai's best seasonal produce.
The Atmosphere
The room is unexpectedly beautiful. Warm-lit cypress walls give way to a glass-fronted walk-in cellar holding more than 500 bottles — including several Grand Vin formats and a rotating selection of rarities that act as a quiet floor show from most seats in the house. Floor-to-ceiling river windows pull the Nakanoshima view into the room at sunset. The feeling is less osteria, more small European hotel dining room lit for a photograph.
Service is led by a sommelier trained in the same European houses Kakihara came through. He will happily talk you through Sicilian whites you have never heard of, if that is what you are after.
What to Order
There is a multi-course omakase and a shorter carta depending on the night. The signature course is potato gnocchi — a single-ingredient dish that shows the chef's hand completely. Expect Italian architectures rebuilt with Japanese produce: a risotto built on Nishiki rice with porcini and Kobe beef stock, a crudo of Osaka-caught aji dressed with Sicilian olive oil and yuzu, agnolotti stuffed with Kyoto vegetables and a sauce américaine finish.
The wine pairing is where Rooots earns its reputation. The cellar leans Italian — Barolo and Brunello represented deeply — but the sommelier will happily move you into Burgundy or Northern Rhône for the meat courses. Non-drinkers are served a thoughtful tea pairing from Uji.
Best Occasion Fit
Rooots Nakanoshima is an exceptional proposal restaurant: intimate, river-view, a glass cellar for the inevitable photograph, and a sommelier who can be quietly briefed to bring a specific bottle out at the right course. Equally, it is an ideal first-date room for a guest who appreciates European fine dining but has the sophistication to recognise that what makes this one different is Japan.
