Located on the remote Japanese island of Okinawa at 20-feet above the ground, the Gajumaru diner was constructed to resemble a massive treehouse. Customers enter the nature themed restaurant thorough a stairway and elevator located inside the trunk of the structure, and can enjoy locally grown ingredients while overlooking the streets of Okinawa. Hit the thumbs for a closer look at this awesome dining location in Japan. [PSFK]
