Unagi Hasegawa is a specialty eel restaurant on the shore of Lake Ashi, tucked right beside the first torii gate of Hakone Shrine and facing the Motohakone pirate-ship pier. Opened in November 2024, it grills eel to order, letting the fish's natural richness shine through. The signature dish, Una-ju Ichimatsu, arranges kabayaki (soy-glazed) and shirayaki (unglazed) eel in a checkerboard pattern over rice, paired with local Kanagawa sake and a seasonal fruit dessert called Ryujin no Tama. A casual, convenient stop for travelers exploring the shrine and harbor area.
