After a year of restoration following devastating typhoon damage, the Glowing Mushroom Night Walk on Hachijojima—an island south of Tokyo—returns for the 2026 summer season. This unique event, run by the Hachijojima Tourism Recreation Research Association (NPO), invites visitors to experience the mysterious world of bioluminescent fungi, learn about the science behind their glow, and witness the resilience of both the island’s ecosystem and its community.

Typhoon Recovery: Nature and Community Rebound
In October 2025, Typhoons 22 and 23 struck Hachijojima, causing severe damage to the Hego no Mori forest trail and the “Glowing Mushroom Forest.” The storms brought down trees, caused landslides, and destroyed walking paths, forcing the Night Walk’s suspension. Restoration required months of work, including community-driven crowdfunding and careful environmental management. The 2026 reopening is a testament to both the island’s natural resilience and the dedication of local residents and supporters.
What to Expect: Guided Night Walk and Bioluminescence Discovery
The main Night Walk program is a one-hour guided tour (19:30–20:30) through Hachijojima’s lush subtropical forest. Participants, equipped with proper clothing and led by experienced guides, search for clusters of glowing mushrooms—tiny fungi that emit a gentle greenish light from the forest floor and fallen leaves. On clear nights, the experience is heightened by the Milky Way overhead and the luminous fungi below, creating a rare double spectacle of natural light. Guides explain the ecology of these mushrooms, their role in the forest, and the ongoing scientific mysteries of bioluminescence. The program is open to adults and children aged 5 and up (minors must be accompanied by a guardian), making it suitable for families, students, and nature enthusiasts.
Premium Night Lab: Science in Action
New for 2026, the “Premium Night Lab” is an optional, small-group program (10 participants per session) held after the main walk. This 30-minute session offers a behind-the-scenes look at mushroom cultivation and hands-on experiments to explore how and why living things glow. Participants learn about the mechanisms of bioluminescence not only in mushrooms but also in other organisms such as fireflies. The Premium Night Lab is available only to Night Walk participants and requires a separate fee and advance booking.
Cultural and Scientific Context: Wonder and Respect
Japanese culture places high value on the appreciation of subtle natural phenomena. The Night Walk embodies the spirit of mono no aware—an awareness of the beauty and impermanence of nature. This event encourages a “sense of wonder,” inviting participants to discover small miracles hidden in darkness. The program is designed as both a sightseeing and educational experience, connecting visitors to the island’s unique ecology and the broader mysteries of life. Organizers emphasize environmental stewardship: touching mushrooms or straying from the guided path is strictly prohibited to protect the fragile ecosystem. Photography is allowed only with handheld smartphones; tripods and bright lights are not permitted to minimize disturbance.
Documented Facts: Science, Not Folklore
The glowing mushrooms of Hachijojima are a well-documented biological phenomenon. While their mysterious light has inspired wonder, the event’s focus is on scientific observation and environmental education. The precise mechanisms and ecological roles of fungal bioluminescence remain partially unexplained, making the experience both enchanting and intellectually stimulating. No folklore or supernatural traditions are promoted as part of the program; the emphasis is on real-world discovery and learning.
