Itayagawa Firefly Viewing (Saigo)

板屋川のホタル(西郷)

Gifu · Chubu

板屋川のホタル is a stretch of the small Itayagawa river in Gifu City's Saigo district, where Genji fireflies typically begin appearing from late May and dance in numbers through their June peak — best viewed 8-9pm. The local Saigo Firefly Festival (西郷ほたるまつり) runs on weekends through the season, organised out of the Saigo Community Centre.

Why it's hidden

It is a residential-district river most travellers driving the Tokai-Kanjo Expressway pass directly over without knowing it is there.
