What Is WONDERHOLIC JAMBOREE?
WONDERHOLIC JAMBOREE is a three-day urban culture festival where people, communities, businesses, shops, and artists active in Hiroshima come together across genres. Food, markets, music, art, plants, fashion, barber culture, and projects highlighting the appeal of the local area all gather in the heart of the city, creating a diverse mix of content.

Hiroshima Botanical Garden (ひろしま植物園)
This is a market where plants themselves, along with spaces and expressions built around them, come together with the people who grow and showcase them. Visitors can do more than just buy — they can see, touch, and talk with vendors to discover a new appreciation for plants.
Early Bird Marche
Under the theme "a wonderful day starts in the morning," this market offers fresh vegetables, food, and items that bring color to everyday life, all enjoyable from early in the day.
ARTY BLOCK PARTY
Live music, DJ sets, exhibitions, live painting, and more offer a chance to experience the work of artists active both in Japan and abroad.
HIROSHIMA BARBER'S FES 2026
Free haircuts, hairstyling experiences, and exhibits from manufacturers highlight the appeal of barber culture. A charity project supporting children will also be held.
SWAPMEET&MARCHE
A swap-meet zone packed with everyone's own sense of "wonder," where visitors may discover new encounters they never expected.
Scenes from the 2025 Festival
The inaugural 2025 edition drew more than 20,000 visitors over its three days.
Three Days in Central Hiroshima
In the heart of Hiroshima, the festival brings new encounters over three days that people of all ages, from children to adults, can enjoy — with family, friends, a partner, or solo, each visitor can experience new culture and new people in their own way.
The venue, HIROSHIMA GATE PARK, sits right in central Hiroshima City. Building on 2025's turnout, the 2026 edition is expected to expand further, with around 30,000 visitors anticipated.
See, eat, listen, touch, and connect — WONDERHOLIC JAMBOREE 2026 brings new culture and new choices to the streets of Hiroshima.
