Shimabara Onsen

Natural hot spring with sourced springs

Shimabara Onsen, has adopted the unusual "hot spring centralized management" system in Showa (time period) across the country.
Currently, we are drawing from the 2nd source of Masui Pond, which has a hot spring water temperature of 41.3 ℃ and a daily hot water amount of about 53,345 tons.

Shimabara Onsen is colorless and clear (*) and can be neutral in nature, it can be bathed without touching the skin gently, especially for cuts, burns and chronic skin diseases.
※Hot spring ingredients may become turbid by contact with air.

【About deposit in bathtub】
With source change, there are black deposits in the bathtub, but due to hot spring ingredients, it is harmless to the human body.
Manganese ions in the hot spring component touched the oxygen in the air, oxidized and turned black.
If you rinse with hot water it will fall, so please drop it well when you leave the Large Bath.

※We do not go to one-day hot springs.
