Tokyo Somei Onsen Sakura

Though it's best visited during cherry blossom season, when the somei-yoshino trees on the premises are at their finest, this onsen bathhouse has enough going for it to be worth a look any time of year. The sodium chloride-rich waters may not be much different to what you'd find at many other baths in the city, but at Sakura they're filtered to remove the colour and smell.
