Kusatsu - Gunma Prefecture

Some of the best Japanese natural hot springs (onsens) on Honshu Island are to be found here. The slightly acidic water with the mild smell of Sulphur will gently exfoliate your skin and leave you feeling fresh as a baby.

The best onsens here are all offered for free, with the best being in the centre of town in antique buildings. This charming town has a free foot spa too.
