Hamo season: the elegant pike conger that defines a Kyoto summer (and Gion Matsuri, July 2026)

One fish, one season

If unagi is Tokyo's midsummer fish, hamo (pike conger) is Kyoto's. In season from mid-May to mid-September, it is the elegant, faintly sweet white fish that appears on every serious Kyoto summer menu — in kaiseki, in tempura, simmered in a clear broth, or blanched and chilled. It is so tied to the season that locals call Gion Matsuri — the month-long festival running 1–31 July 2026, with its great float parades on 17 and 24 July — the 'Hamo Festival.'

Why it took a city to perfect it

Hamo is brutally bony. To make it edible, a chef performs honekiri — 'bone cutting' — slicing the flesh into a comb of fine cuts (roughly 24 cuts per sun, about 3cm) without severing the skin, so the tiny bones are broken but the fillet holds. It is one of Japanese cooking's signature skills; a Kyoto saying holds that a chef isn't fully trained until the knife obeys. Historically, hamo's hardiness is the whole point: it survived the hot journey from the seas off Awaji and Akashi to land-locked Kyoto, making it the rare fresh fish the old capital could eat in high summer.

How it reaches the table

The signature dish is hamo no yubiki (also hamo-otoshi): the cut fish is briefly blanched so the flesh blossoms into white petals, chilled, and served with tart plum sauce (umeboshi) or karashi-su miso — cool, clean and quietly luxurious. You will also meet hamo no otsukuri (as sashimi-style), grilled hamo lacquered with sweet sauce, and hamo-suri dumplings in a clear summer broth. The flavour is delicate; the pleasure is texture and the cool astringency of the plum against the heat.

What each diet should know

Hamo is fish, so it suits pescatarians but not vegetarians or vegans. The chilled yubiki with plum sauce can be naturally light, but check: ponzu and many sauces use wheat-based soy sauce (not gluten-free), and dressings may contain dashi or mirin. It is essentially never halal-certified. As always with kaiseki, state any need at booking, not on the night.

Where to eat it

Hamo is at its most authentic in Kyoto. Our directory's Tousuiro, a tofu-kaiseki house on the Kamogawa in Kiyamachi, is a refined seasonal Kyoto kitchen where summer menus feature it. In Tokyo, the season reaches the city's top kaiseki counters: Kagurazaka Ishikawa, the English-friendly Ise Sueyoshi, and Ginza Kojyu all build seasonal courses and can present hamo at its peak — ask when you reserve. Go in June or July for the freshest fish, and let the chef lead.
