The Prince Sakura Tower Tokyo, Autograph Collection

What the classifiers highlight

Three minutes on foot from Shinagawa station, this tower sits inside a former royal garden, renovated in 2013 by architect Ryu Kosaka under a wa-modern brief mixing contemporary lines with traditional joinery. Forbes walks through the garden itself: pine trees, a rock-lined carp pond, a shrine and a mon gate, reachable from rooms with wide windows.
