What Is Bios no Oka?
Bios no Oka is a subtropical nature theme park located in Uruma City in central Okinawa. "Bios" means "life" in Greek, and true to its name, the park preserves and showcases Okinawa's rich natural ecosystem. Spanning approximately 75,000 tsubo (about 25 hectares), it features subtropical forests, a lake, orchid gardens, and animal interaction areas — making it a perfect spot for families with children of all ages to immerse themselves in nature.
Jungle Boat Cruise
The top attraction at Bios no Oka is the Jungle Boat Cruise along the park's lake. The boat covers approximately 1 km over 25 minutes, with a guide providing entertaining commentary about the waterside subtropical plants and animals. Tropical ferns, Gajumaru (banyan) trees, and orchids create a lush jungle landscape that feels like an Amazon adventure.
