Residence Hotel Ryogoku

The chef defends the traditions and skills of Edo-style sushi while showing creativity with some innovations of his own. Japanese halfbeak and horse mackerel are accented with ginger and mirin–soy reduction; simmered conger eel is served both salted and dipped in eel sauce for taste comparison. Nigiri is shaped using rice seasoned with red vinegar—a showcase of techniques cultivated over years of experience. Treading the path of the sushi chef was a dream in his teenage years. Steady devotion to craft is a lesson learned from sushi.

Tempura pieces are deep-fried in high heat to draw out moisture for a fragrant coating. Shrimp are served two pieces in succession, fried at different temperatures to contrast the texture of rare and medium. Depending on availability, you might receive two kinds of squid, each imparting a different flavour. On the wall hangs a work of calligraphy — a gift from his mentor — casting a quiet but discerning eye over the apprentices at work. It reads ‘Menkyo Kaiden’: ‘attain full mastery of the arts of our trade’. The words seem to whisper, ‘Catch up, and surpass me.’

This self-taught master of tempura was captivated by its craft of deep-frying and the pursuit of flavour. He hones his technique by attuning his senses to the batter’s consistency, the precise temperature of the oil and the crackle as it fries. Some ingredients may be cooked at lower temperatures, or steamed, drawing out or retaining moisture. Careful control of the Maillard reaction lends each piece a fragrant, golden crust. His distinctive tempura, which evolves day by day, is not to be missed.

‘Harmony’ and ‘circulation’ are the keywords of this dining experience. Through his partnerships with farmers, the chef returns compost to revitalise the soil. The prix fixe presentation starts with a bowl of soup. Vegetable ends are used in the soup’s creation, expressing a wish for a society that doesn’t waste food. Prepared with French techniques, the fare is simple and light. The grey of the interior creates something of a laboratory feel.

Satoru Asahina pursues a gastronomy of ‘traditional heritage with modern innovation’. He delves into the history of French cuisine to reconstruct ancient recipes with his own interpretations. The prix fixe meal begins with a colourful amuse-bouche and proceeds to plates adorned with multi-layered culinary creations. Consommé pressed through a siphon with a flourish and desserts paraded on trolleys catch the eye. Classic cuisine tuned up to point to the future.

Taking pride in domestic ingredients, the restaurant presents a distinctly Japanese approach to French cuisine. Dishes are light, with restrained use of fats and oils in line with modern tastes. Seasonal menus highlight fruits such as peaches and strawberries from local farmers, making the most of their natural character. Courses featuring sweetfish, chestnuts and mushrooms are also tempting. ‘La Paix’ means peace, expressing a wish for a harmonious table where producers and chef come together in mutual understanding through food.

Black, white and orange are the tricolore of ‘Watanabe-ism.’ Black represents faith that cannot be tainted; white, the freedom to become any colour; and orange, the flame manipulated by the chef. On offer here is a fusion of French and Edo food cultures. Sobagaki is emulsified using French techniques; local Japanese elements include kaminari-okoshi, a roasted and flavoured mochi cracker; and monaka, a sweet of azuki bean paste sandwiched between crisp wafers. Watanabe-ism has deep roots in Asakusa-Komagata.
