Fireflies in their natural habitat blue apple with permission

Did you know that you can see fireflies in Saitama all year round? The Tobu Zoo is home to the first and only firefly house in the world. And while it is fascinating to see fireflies anywhere or anytime, there is nothing quite like seeing them in the wild in their natural habitat. Chichibu is one of the few locations in Saitama that you can do just that: behold the stunning scene of fireflies in unadulterated surroundings.

I have visited the firefly house in Tobu Zoo and had the unforgettable experience of seeing fireflies in the wild in both Kanagawa and Akita prefectures. Nothing compares to the first hand experience in nature. I have yet to get Chichibu myself to see the fireflies as we have had children since we moved here. Maybe in a few years when the kids are older, because as it is now, they go to bed just as the fireflies are rising; about 7 pm!

I have collated information over the years about fireflies in Saitama. There are a number of parks that have firefly events. And while, unlike Tobu Zoo’s firefly house, they are outside and in nature, they are not native to the region. More often than not, parks that have firefly events are with fireflies that have been captured for the purpose. Due to this reason, the time frame for seeing them is quite short as they tend to die sooner out of their natural environment. However, in Chichibu, particularly in the Minano town area, the fireflies are wild and free! And thanks to that the viewing period is typically longer, sometimes up to two months long.

The season of when you can see fireflies varies slightly from year to year. Some years you can see them in early June, but mostly it is from mid to late June in any year. It will depend on whether they are the hime, heike or genji variety. The hime tend to come first around mid June. The heiki and genji can often be seen in early July.

Locations in Chichibu where you can see fireflies (not all natural environment):

  • Shimoyoshida – featured below
  • Chichibu Muse Park: 2022 event information here
  • Terasaka Rice Terraces is particularly beautiful as they have a candle night in conjunction with the firefly viewing event. Generally in early July. Unfortunately, the Terasaka Rice Terrace firefly and candle night will not be on in 2022. It was also cancelled in 2020 and 2021 due to the pandemic.
  • Ogawa is about two kilometers from Yoshida Genki Mura / Kakkaku dam in Kamiyoshida. Please note, there is no parking lot near the firefly viewing location. The closest probably is Yoshida genki mura.
  • Kamimachi Hotaru Kaiba is an 11 minute walk from Seibu Chichibu station and relatively close to Hitsujiyama Park. The official period for viewing in Kamimachi is from Friday June 3rd to Sunday July 10th. As of June 16th 2022 dozens have been confirmed to be flying nightly.

Fireflies in their natural habitat at Shimoyoshida

They estimate there are about 300 fireflies in the Shimoyoshida area of Chichibu. Specifically the area around Fruit Road and near the Arakawa close to Akahiragawa Yoshidagawa Mizube Park.

They are Hime-hotaru, hotaru means fireflies, which come out up to two weeks earlier than the other two varieties of fireflies found in Japan (Heike and Genji). In addition, they are also faster maturing than the Heike and Genji variation and so turn on their lights sooner to attract females during mating season! However, the best time to see fireflies in Shimoyoshida is generally from mid June to early July. But as of June 16th there numbers have not yet been confirmed for 2022.

They can often be seen from 7 pm, but the recommended time is about 8.30 to 9.30 pm. However, there is no guarantee you can see them at this time either, as sometimes it is closer to midnight before you can see the flickering fireflies. A level of patience is required for firefly viewing in nature!

If you read Japanese blue.appleさん has fantastic, detailed information about Shimoyoshida:  BLUE APPLE BLOG. Even if you don’t read Japanese, you should check out his firefly photos; absolutely amazing. (I have no affiliation to this site, just an admirer).

Access Fireflies at Shimoyoshida

It is fairly difficult to get to the area by public transport, due to the infrequency of buses, but it is possible. However, this location is best suited to those coming by car. It is commutable from Tokyo, about 2 hours one way. Parking is available at the Akahiragawa Yoshidagawa Mizube park for those coming by car.

Seki Chiku No Hotaru, also in the Shimoyoshida district, is about a 20 minute walk from Akahiragawa Yoshidagawa Mizube park. But there is a farm in the area, Tadakane farm, where you can park for firefly viewing. It used to be free, but I heard they now request a 300 yen contribution fee. Unfortunately, I can’t find an official website to confirm this! In 2021, you couldn’t use the parking or visit the firefly area, but there is no notice to that effect for 2022. Please check with the Chichibu Navi website for any updates.

Thanks again to Blue Apple さん for permitting me to use his stunning Shimoyoshida firefly photos for this blog post.

      Who knows, maybe there is some structure in their society and the patterns are deliberate? I haven’t the foggiest, but Blue Apple san is thankfully an excellent photographer and got these great shots, because fireflies are soooo hard to capture on camera. Thanks as always for commenting Andy
