The just-unveiled gold-tinted Shiki-shima Japanese sleeper train, designed by Ken Kiyoyuki Okuyama, takes luxury to a new level. The 10-car train (announced back in 2014) has 17 rooms—two suites and 15 smaller spaces, all of which have a bed and a private bathroom—but the interiors need to be seen to be believed. With floor-to-ceiling windows, passengers can see the passing world uninterrupted; perhaps from Brentwood sofas in the communal areas. There are also washi paper walls, opulent carpets, chandeliers, and the two-story Shikishima suite even features a cypress bathtub. Tickets start at $2,865.
