Take a dip at Thermae-Yu Hot Spring
Shinjuku’s Kabukicho district is better known for partying than wellness – but when do you need rejuvenation more than after a night on the town? Thermae-yu offers spa luxury for those on a budget, using genuine onsen water supplied daily from Japan’s Izu peninsula. The six-floor complex has both indoor and open-air baths, including a jacuzzi and carbonated water bath (which is great for your skin). After your soak, head for the spa for scrub and hot-stone treatments. The hot spring is conveniently located in the middle of Shinjuku and is open 22 hours a day, meaning even the busiest people can find time to unwind.
