Issyuku Hotel Asakusabashi

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.

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.

‘Tonkatsu is food for the masses’, explains the second-generation chef, as he aims to serve up fare that is familiar and comforting. Copper pots polished till gleaming and plain wooden counters display a craftsman’s spirit. Two pots are used: one containing hot oil and the other cooler oil. Pork loin is shorn of extra fat and thinly battered. Tonkatsu is the star attraction, so no meat is added to the pork miso soup. As the chef works, a photo of his father in chef’s whites watches over him.

The motto on the noren, ‘After having tempura, finish with soba’, declares the personality of Sonoji. The chef learned the arts of both soba and tempura when he ran a shop in his native Shizuoka. For tempura pieces, he focuses on the bounty of Shizuoka’s Suruga Bay and traditional Edo seafood. Vegetables shipped directly from farmers accentuate each season. The soba served at the end of the meal is topped with kakiage of sakura shrimp, ‘the jewel of Suruga Bay’. The unique menu reflects each stage on the chef’s gastronomic journey.

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.’

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.

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.
