What Gunma is

In the middle of Kusatsu is the yubatake — a wooden field of channels in the open air, where the spring water is run along troughs to cool before it reaches the baths. Steam comes off it day and night, and the whole town smells faintly of sulphur. The water arrives at around 50°C or hotter, which is why they cool it this way rather than adding cold water — adding water would weaken it. There is a show, several times a day, where it is stirred with long wooden paddles.

Spring in Japan — seasonal artwork
March – May

Snow leaves the valleys in April. Fresh green in May, and the highland roads reopen.

Summer in Japan — seasonal artwork
June – August

Wet in June. Kusatsu sits at 1,200 metres and stays cool through August — a hot-spring town you can bear in summer.

Autumn in Japan — seasonal artwork
September – November

Autumn colour through October and November, and the best walking weather of the year.

Winter in Japan — seasonal artwork
December – February

An outdoor bath in falling snow is the point of this prefecture. Ski areas open, and roads may need chains.
