Although this towering concrete treehouse isn’t really green, (unless tree imitation counts as ‘green’), we couldn’t help but be awestruck by its sheer craziness. We thought it worth a post, just for the picture alone. The Naha Harbor Diner in Okinawa, Japan is a life-size rendition of a banyan tree, also known as gajumaru. The aptly-named Banyan Town shopping center near the entrance of Onoyama Park features a twenty foot tall tree with a pan-Asian restaurant nestled amid its branches. Accessible by a spiral staircase around back and an in-trunk elevator, the restaurant specializes in locally grown and organic harvested foods fresh from the farm.
