[Archival Edition] What is Japan's oldest hot spring? A complete explanation of Japan's three oldest hot springs and the oldest inn!

Hot springs have been loved by people since ancient times, and as history has accumulated, they have developed a unique culture.

In this article, we will thoroughly explain the three oldest hot springs in Japan (Dogo, Arima, and Shirahama), as well as the oldest hot springs in Japan. We will also introduce access information and sightseeing plans.

What is the oldest hot spring in Japan?

There are several hot springs that are said to be the "oldest"

When you hear "Japan's oldest hot spring," many people probably think of Dogo Onsen in Ehime Prefecture, Arima Onsen in Hyogo Prefecture, or Shirahama Onsen in Wakayama Prefecture. In fact, there are other hot spring areas that are said to be "Japan's oldest" besides these. The reason for this is the difference in records, such as when they appeared in ancient documents and when members of the imperial family or historical figures visited them.

For example, the Kojiki (Records of Ancient Matters) (712) states that Prince Karu was banished to the hot springs of Iyo at Dogo Onsen, and the Nihon Shoki (Chronicles of Japan) (720) records that Emperor Jomei visited Arima Onsen in 631. The Nihon Shoki also contains an article about Empress Saimei's visit to Shirahama Onsen in 658. Some hot springs have legends that go back even further, and the title of "oldest in Japan" changes depending on which document is considered the oldest.

The history of hot springs explained through the "Nihon Shoki" and "Manyoshu"

The Nihon Shoki and Kojiki are historical books that describe the origins of Japan, and contain many records of emperors and members of the imperial family visiting hot springs. These prove that hot springs were already popular as therapeutic baths and sacred activities during the Asuka and Nara periods.

Additionally, the Manyoshu contains several poems about hot springs, which show that people at the time enjoyed hot springs not only as a place to relax the body and mind, but also as a subject for waka poetry. These classic descriptions convey the depth of Japan's hot spring culture to the present day.
