Unagi no Kabayaki — Hamamatsu Grilled Eel on Rice

Hamamatsu is Japan's eel capital, producing 40% of the nation's farmed unagi (freshwater eel) from Lake Hamana's brackish waters. The city's signature dish is unagi no kabayaki (うなぎの蒲焼き) — butterflied eel grilled over charcoal, basted with sweet soy-based tare sauce, and served over rice as unadon (bowl) or unajū (lacquered box). The preparation requires precise technique: steaming to remove excess fat, grilling to crisp skin while keeping flesh moist, and applying tare at exact intervals to build caramelized glaze without burning.

Hamamatsu eel restaurants range from 100-year-old establishments with multi-generation recipes to modern chains. The traditional serving style uses unajū (lacquered box with multiple compartments) — eel on rice in main section, liver soup and pickles in side compartments. Premium grades include extra-thick eel (特上, tokujo) and wild-caught (天然, tennen) which is increasingly rare and expensive.
