fireflies chichibu

Firefly viewing and daylilies during rainy season, at Chichibu Muse Park, Ogano Town, Chichibu District, Saitama Prefecture, Japan. Like many parks around Saitama Prefecture, Chichibu Muse Park raise fireflies and offer a supervised viewing event once a year. Its usually during rainy season, but rainy season ended earlier than ever before! The date depends on the conditions that year, but its generally really late June or very early in July. In 2022, its the latter. In addition, the daylilies in the park tend to reach full bloom around the same time as the firefly viewing event. (No guarantees though, it will of course depend on Mother nature!)

Firefly Viewing

The firefly viewing event in Chichibu Muse Park is very popular, attracting people from near and far. Moreover, it is a free event. It is held annually on a date in either late June or early July. The date depends on the life cycle of the fireflies in a given year. They allow up to 500 participants to partake in the firefly event. Moreover, the park attendants not only show you to an area where you can view fireflies, but they also offer some information about the life of fireflies.

As of June 28th 2022, only about 30 fireflies have been confirmed so far.

Despite the pandemic, the 2021 firefly viewing event went ahead, with some minor changes. It is scheduled once again for 2022. However, please note – like all events during the pandemic – there maybe last minute changes or even a cancellation due to the Coronavirus. In 2020 the event was cancelled last minute on account of the Coronavirus. Please do check with the official website, linked in the firefly event paragraph below daylilies, for any last minute changes.


The firefly viewing is a night time event, but if you are visiting the expansive park during the day, you can usually see daylilies in bloom in early July. Chichibu Muse Park is renowned for its daylilies. They are located near the South Entrance car park. The daylilies, also known as Hemerocallis, typically bloom from mid June to early July. The official website generally starts to update on the condition of the daylilies from around mid June. In 2022, the early blooming variety started to bloom around June 9th.
