Recognized by the Okinawa Education Commission as equivalent to a museum, the garden can benefit from international exchanges which allow it to own many rare plants that are protected species in other countries and whose commercial export is restricted.
由於被琉球教育委員會認定為「博物館相當設施」，憑此身分與國際交流，因此擁有許多外國列入保護、限制商業出口的奇珍異草。
