Yanbaru (in the north of Okinawa mainland) is a treasure trove of plants. Various plants bear flowers and fruits depending on the season. Yanbaru is also home to the largest acorn in Japan, the Okinawa white oak (Quercus miyagii). Shimasarunashi, a relative of the kiwi fruit, is the best of Yanbaru's luxury fruits and tastes exactly like a kiwi. This tour offers you the opportunity to see and observe many of these plants.
