Time Out says
UPDATE: Wakana closed its doors permanently at the end of 2016.
Hidden among the winding alleyways of Kagurazaka, Wakana used to be known as a writers' retreat, frequented by famous authors like the screenwriter Yoji Yamada. You'll be sure to receive a warm welcome from the proprietress, a lovely lady who's been running the inn since its founding. The breakfast is simple but carefully prepared to perfection, starting with the rice, which is served in an old-fashioned wooden bucket.
