Where to Find Fireflies in Tokyo

Catching fireflies as a child is a fond memory for many people. In Japan too, fireflies, or hotaru, create spectacular night displays of twinkling stars. Even in Tokyo, you can see fireflies. The charming light-makers only live in places with pure water. Marvel at their lights from sunset to around 21:00, and watch these insects illuminate the night.


  • Fireflies like warm, humid air, as well as and clean, pure water.
  • Firefly numbers are decreasing around the world so it’s important to be gentle.
  • Do not catch the fireflies. Simply observe them quietly.
  • If you use a flashlight, try to aim it at the ground so you don't confuse the fireflies.

Become surrounded by an abundance of nature and breathe the fresh air of Yuyake Koyake Fureai Village. In this area of Hachioji, Tokyo, you can experience a lush green world that makes you forget that you are in the city. If you want to see the beautiful fireflies, there is no better time than June to visit. Watch the little bugs speckle the sky with their lights. The fireflies weave between the trees, creating a magical, glowing forest. They are best viewed between June 13 and 28, from 18:00 until shortly before 21:00. Yuyake Koyake Fureai Village holds many special events all year long, but their fireflies are not to be missed.

A Long History of Fireflies: Hotaru Park

Tamagawa River is a beautiful sight no matter the time of year, but seeing it alight with fireflies makes it into something straight out of a fairy tale. Head to Fussa to the aptly named Hotaru Park, only one hour west of Tokyo, to see this free firefly festival in mid-June. 500 fireflies are released along the banks of the Tamagawa River to create swirling lights that reflect off of the water and sparkle in the sky. Not only will the charming bugs welcome you, but you can also find food stalls and live stage performances for a lively Japanese festival atmosphere. Take the train to avoid crowds and plan to arrive around 20:00, as the festival finishes around 21:00. The fireflies, of course, will be staying long after.

Fireflies Surrounded by Gentle Nature: Osawa no Sato

Visit this firefly spawning ground to get a chance to see fireflies in their natural habitat at Osawa no Sato in Mitaka. Floating in the paddy fields are cabbage leaves, which are preferred by snails, which serve as food for the firefly larvae. This encourages the newly-formed fireflies to stay in the area longer as their mating season begins, and they signal to one another using an orchestra of lights. Take a stroll down the boardwalk through tall grass, and be mesmerized by the dancing illuminations. Mid-June is the best time to see the fireflies. The small insects make their nightly appearance from around 19:00 to 21:00. The park asks that guests please not use flashlights, strobe lights, or flash photography while looking for fireflies.

Valley of the Fireflies—Yozawagawa River

Appreciate the silence of dusk as you walk through Yozawagawa River near Akigawa Valley and Seoto-no-yu, with the fireflies flying around you. Stroll from Tokuun-in Temple, a serene village temple, and discover your peace of mind and inner Zen. The banks of the Yozawagawa River are another popular option for firefly-watching in Akigawa Valley. The river is cleaned by locals, and the pure, flowing waters draw fireflies to it. Take a summer walk along the cobblestone path next to the river, and watch as the insects dart over the surface of the waters. The best time to see the fireflies in this area is from 20:00 to 21:00. You will love the quiet serenity of Akigawa Valley and its fireflies.
