HANA-BIYORI, a sensory-stimulating flower park operated by Yomiuriland Co., Ltd., will host the firefly viewing event 'Hotaru Biyori' from May 23 (Sat) to July 1 (Wed). Yomiuriland has been dedicated to firefly breeding since 2009, maintaining a stream fed by natural well water specifically for these viewing events. This year's event spans 35 days. Until mid-June, visitors can enjoy the powerful and impressive light of Genji fireflies, followed by the delicate and emotional glow of Heike fireflies. Date-specific firefly viewing tickets will be sold in advance. During the period, a Tanabata strip decoration corner will be set up, and staff will hold daily 'Firefly Study Sessions' to explain firefly ecology in an easy-to-understand way. Please spend a healing moment wrapped in the soft light of early summer.
