Toyotomi Onsen — Spring Water Analysis, Temperature and Snowfall
豊富温泉 · Hokkaido
Toyotomi Onsen (豊富温泉) is a nationally designated onsen town in Hokkaido. We measured how much snow its winters bring, using the same method as for the 3,069 ski areas on this site.
How this place came to be
In 1925 someone was drilling for oil here, and hot water came up with natural gas instead. That is where it starts. The flow was 47 litres a minute then; it is 273 now, at 30°C.
Toyotomi lies about 40 km south of Wakkanai and is usually called the northernmost onsen district in Japan. It sits on a plateau 20–40 m above the sea, with Mount Rishiri on the horizon and dairy pasture below. There is no rainy season here and no need for air conditioning in summer; in winter it drops to −20°C.
The water carries petroleum. The tar compounds in it are held to calm inflamed skin, and people with atopic dermatitis and psoriasis travel here from all over the country to soak for weeks. The town's own bathhouse has a separate cooler pool, built so that people can stay in a long time without feeling watched.
Eight places to stay; three of them pipe the source straight into the bath.
About 10,000 cubic metres of natural gas still comes up every day — more than the village can burn.

These are analyses of hot spring sources, not a list of baths you can visit. They date from 1910 to 2005, many from decades ago, so today’s temperature and chemistry may differ. Names are as recorded in Japanese. Temperature and pH bands follow Japan’s standard for analysing hot springs.

These snowfall figures are estimates
The snowfall shown here is an estimate produced by a weather model, not a record of what actually fell.
We compared it against 63 Japan Meteorological Agency weather stations to see how far off it is. On average it comes to about six tenths of the real figure — it runs low. And it runs low by different amounts in different places: some read barely a third of what was measured, others match almost exactly. Mountains tend to read lowest.
We tried scaling everything up by a fixed amount to correct for it. It barely helped, because the error differs from place to place.
So treat these numbers as a guide to roughly where somewhere sits, not a precise figure. There is no meaning in the gap between first and second, or between 30th and 35th. Large differences between regions are real and can be read as they are.
We considered correcting the figures against the observations. But this ranking covers 3,069 ski areas across ten countries, and only Japan can be checked against weather stations. Correcting Japan alone would lift Japanese resorts above the Alps and North America with nothing behind it. Every place here is measured the same way instead.
Where a nearby weather station can be used, we print what it actually recorded on that ski area's own page.
