Yunoura Onsen — Spring Water Analysis, Temperature and Snowfall
湯ノ浦温泉 · Ehime
Yunoura Onsen (湯ノ浦温泉) is a nationally designated onsen town in Ehime. 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 Imabari, Ehime, on the eastern side of a peninsula jutting into the middle of the Inland Sea. It was the first National Health Resort Hot Spring in Shikoku.
The history of bathing here reaches back to the Nara period. Emperor Shomu founded a provincial convent alongside the provincial temple in this district, and Empress Komyo established a dispensary — a medical foundation. The area is remembered as a place of rest and treatment using water that came up of its own accord.
The source now in use, however, was drilled in 1976. Twelve centuries of history; half a century of spring. That gap is what the place is. It yields 780 litres a minute, clear and soft, carrying radon and fluoride.
One bathhouse here invented shiitake grown on logs watered with the hot spring, and holds a mushroom festival for it every year. The roadside station has a tap where you can take the water home.
The coast nearby runs about eight kilometres of white sand and pines, and is on the national list of a hundred fine shores. A lacquerware workshop with 250 years behind it can be visited.

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.
