鳥川ホタルの里 covers the whole of Torikawa-cho in eastern Okazaki, long affectionately called 'Tokkawa,' where wild Genji fireflies gather in numbers that regularly exceed 1,000 on peak nights in mid-June — the 'Hometown Japan' spring-water designation the area holds (平成の名水百選) is part of why the population stays this strong. In April 2012 the town converted its closed elementary school into 'Hotaru School' (ホタル学校), a base for the conservation programme and for environmental-education visits, with the old schoolyard used as parking during the season.
