The historical garden Chinzan-so is famed for its Japanese fireflies, or hotaru, and in honor of the firefly-viewing season, the Four Seasons Hotel Tokyo at Chinzan-so will offer a special Hotaru Stay Plan from May 21 through July 10.
The 7-hectare garden is one of the largest venues in Tokyo for people to watch fireflies.
Fireflies live only around clean water and light up the early summer nights from late May to the beginning of July. Spring water from the Chichibu Mountains flows through the garden, allowing two kinds of fireflies, the bigger Genji hotaru and the smaller Heike hotaru, to flourish.
