What this is
Chiikawa Ghost Forest is a themed interactive attraction held as part of the larger 'Odaiba Fan Rising' summer entertainment festival at the Fuji TV Headquarters Building in Odaiba, Tokyo. Running from late July through late August 2026, it transforms the beloved Chiikawa characters — the wildly popular Japanese manga and anime franchise by Nagano — into ghost versions set within a mysterious forest environment. The event features a centrepiece 'Chiikawa Shrine' symbolised by a giant Chiikawa figure, where visitors can participate in classic Japanese summer festival activities including water fortune slips and super jumbo yo-yo fishing. A dedicated 'Chiikawa Odaiba Shop 22F Store' will also open, selling exclusive ghost-themed merchandise and goods tied to the theatrical film 'Chiikawa the Movie: Secrets of the Mermaid Island.' The event blends immersive character theming with traditional summer festival culture, making it a standout attraction during Tokyo's midsummer entertainment season.
Who should go
This event is ideal for Chiikawa fans of all ages, from young children to adult collectors who follow the franchise closely. The combination of interactive activities, shrine aesthetics, and exclusive merchandise makes it especially appealing to families and anime enthusiasts looking for a uniquely Japanese summer experience. The ghost-forest theme and festival games give it a playful, atmospheric quality that casual visitors to Odaiba will also enjoy even without deep knowledge of the IP. Arrive early in the day on weekdays to avoid the longest queues for popular activities like yo-yo fishing.
Good to know
The Fuji TV Headquarters Building is a well-known Odaiba landmark with its own internal event spaces across multiple floors — the dedicated shop is confirmed on the 22F, so plan for elevator queues during busy periods. Entry to the broader Odaiba Fan Rising festival may have a separate admission fee; check the official website for ticketing details as this was not confirmed in available information. Merchandise for popular character events like Chiikawa sells out extremely fast — ghost-themed limited goods and movie tie-in items in particular tend to be gone within the first few days, so early visits are essential for collectors. The venue is air-conditioned indoors, which is a significant comfort bonus during Tokyo's intense August heat. Foreign visitors should note that Odaiba is very tourist-friendly and English signage is available throughout the area.
