[日本語がまだありません。書く暇が出来たら書きます。^^;] It costs about 2,800 yen to get in and then a few hundred yen (I forgets) to use the baths. The 2,800 yen lets you stay until 3AM and you can pay an extra 1,300 yen to stay over night until 9AM. Those who are after cheap lodging may want to check this place out. Map and address here or get off at Minato Mirai station, grab a cab and say "Manyo Club Onegaishimasu."
