Konan Firefly festival

Each year at either the end of May or start of June there is a firefly festival in the Konan area of Kumagaya. The Konan area is perhaps best known for its stunning wisteria, which is currently in bloom. However, the owner will start trimming the wisteria on the 7th. Therefore, tomorrow – the 6th of May – is the last day you can see the Konan wisteria in 2024.

Konan Firefly Festival

Konan firefly festival 2024

Often firefly events in Saitama are for small groups of people who book in advance to do a tour. However, this festival (and the firefly event at the Terasaka terraced rice fields) have no limit on numbers. With the result before the pandemic the festival in Kumagaya attracted about 6,000 people. The festival is called Konan (Kounan) after the area. Konan is famous for the amount of genji fireflies native to the area. Three hundred candle lit lanterns that were made by local school children light the main road from the festival tents to the main area for the firefly viewing. They will be lit from 6.30 pm. There are two kamishibai performances, firefly stories naturally, before that at 5.30 and 6 pm!

Later in the summer there are even more places with firefly events, such as the Kitamoto firefly event (easily commutable from Tokyo) and the aforementioned Terasaka Rice fields firefly and candle night.


Event: Konan Firefly Festival 2024 第16回こうなんホタル祭り

Date: Saturday June 1st 2024, but it will be cancelled if its raining.

Time: from 6.30 pm to 9.30 pm, but the kamishibai is from 5.30 pm. You need to register an interest early, as they will limit viewing to 30 people each time.

Cost: there is no admission fee.

Venue: the parking lot of Kumagaya Culture Hall Pipia 325-1 Sendai, Kumagaya, Saitama 360-0107. View on Google Maps.


The nearest train station on foot is Hirose Yacho No Mori station on the Chichibu Railway line. It takes about 50 minutes. But you can take a bus from Kumagaya Station, bound for Ogawamachi station, to Onuma Park. It is about a 20 minute ride. From the park it is about a ten minute walk. Please note that buses maybe limited. Please research the times to make sure you can still get a bus back at your planned time of departure.

There is parking for 160 cars at Pipia, but it fills up pretty fast. As you can see in the flyer above, there are other nearby parking lots too. They’ve actually doubled the amount of parking available in recent years. There is now close to 700 parking spaces available across multiple parking lots. However, it doesn’t suffice, so where possible its best to come by public transport.
