Hunting Fireflies

The end of May and throughout June is firefly season in Japan. Beginning with the genjibotaru (ゲンジボタル, laciola), you can spot many different varieties of fireflies near clear streams. Firefly viewing is a time-honored tradition and one of the features of Japanese summers. It may be a little difficult to see wild fireflies in the city center, but in places currently engaged in redeveloping the natural environment, and artificially rearing fireflies, it’s possible to view them.

Here we introduce some places in and around Tokyo where you can view fireflies, as well as some seasonal events related to hotaru.

Please note that it is extremely important to be quiet when approaching the fireflies, and not to use flash photography.

Fussa Firefly Festival

During the 50s and 60s, genjibotaru fireflies used to swarm in the trees by the pristine water of the Tamagawa river, and the area was known as a midsummer spot aglow with the insects. Since then the number of fireflies has gone down as a result of urbanization, leading to the creation of a firefly reserve in order to protect their terrain. Nowadays a festival is held there every year, where visitors can enjoy a variety of events while watching over 1,000 fireflies dance in the air.

10 min. from Ushihama Sta., or 7 min. from Kumagawa Sta.

Ukai Toriyama: Hotaru-gari (Firefly Hunt)

Situated in the valley behind Mount Takao, this restaurant’s premises reach almost 20,000m2. Traditional architectural buildings in styles such as gasshōzukuri (合掌造り) and a teahouse, as well as separate sukiyazukuri (数寄屋造) private dining rooms stand in its garden. It goes without saying that this kaiseki (Japanese banquet) restaurant is incredibly famous. Every year, when the season comes around, they hold their “firefly hunt”, where they take down the lights in order to have the fireflies dance gracefully in the peaceful garden. Visitors eat while viewing this scene that could have been taken right out of a painting. A special menu is offered while the “firefly hunt” is on. Even when the hunt is over, it is possible to see the fireflies until mid-August.

Sankeien: Hotaru no Yube (Firefly Night)

With over one hundred years of history behind it, the Sankeien garden is a name most people know for its scenic beauty and seasonal events. At this time of year, that means firefly viewing. Within the spacious park grounds, the best place to see fireflies is at the back near the Kogawa riverbanks (Landmarks: Yokobuean, Kankakyou). Firefly cages have been placed inside the normally closed Kyu-Tomyoji, so that visitors can observe the fireflies close up. In order to avoid the weekend rush and allow visitors to take the time to enjoy themselves, the park is also open on weekday nights. A place to take in the ephemerally beautiful light, the rich greenery and historical sights, and enjoy a scene of otherworldy visions.
