Updated: 13 June 2018
Japan is one of the most volcanically active places on Earth. As a result, the country is rich in natural hot springs and mineral resources, which have played an important role in the traditions and culture of its people. Thanks to some modern advances in technology, Tokyoites no longer have to travel far to find an onsen to suit their needs. These are the city’s best.
