What are Unzen Onsen and Obama Onsen?

Both Unzen Onsen and Obama Onsen are hot spring resorts whose heat source comes from a magma pool deep on the west coast of the Shimabara Peninsula.

We will introduce the characteristics of the two hot springs.

Unzen Onsen: A mountain resort

To get to Unzen Onsen, located in Unzen-Amakusa National Park, which is Japan's first national park, you will have to climb a mountain path by bus or car. Because it is located at an altitude of 700 meters, the temperature is 4 to 5 degrees lower than at the foot of the mountain, and the natural environment is rich.

The surrounding area is filled with the vibrant pink flowers of Miyamakirishi in spring, fresh greenery in summer, autumn leaves in autumn, and frost in winter, allowing you to enjoy the seasonal natural scenery that is so typical of Japan.

As you walk through the city, you'll notice the smell of sulfur wafting from everywhere.

The highly acidic sulfur spring that gushes out from Unzen Onsen has a strong bactericidal effect and is said to be effective against skin diseases.

*Frost...A fantastic phenomenon in which trees are covered in ice when the temperature drops below freezing

Obama Onsen: A High-Temperature Hot Spring with Abundant Water Flow

Obama Onsen is located on the west side of the Shimabara Peninsula. The hot spring town stretches along the coast, with many hot spring inns boasting spectacular views.

The spring quality is a chloride spring with a high salt content. Due to the high temperature and Toyotomi amount of water, pure white steam rises from all over the town.

In the second half of the article, we will also introduce some steamed cooking spots that take advantage of the characteristics of hot springs!

Hot Spring Spot

1. The charm of "Unzen Jigoku" where both people and cats can relax (Unzen Onsen)

Unzen Jigoku is a place with a unique landscape, with steam rising from the earth and the smell of sulfur in the air. There are several routes to take, and it takes about 40 minutes to walk around the area.

Although it has a scary name, Hell, the ground is warm due to geothermal heat, so it is actually known as a relaxing spot for local cats. Recently, the number of tourists who come just to see the cats has been increasing.

At Unzen Jigoku Kobo, you can enjoy hot spring eggs while touring the Unzen Jigoku. Don't forget to try another specialty, hot spring lemonade!

It recreates the taste of the lemonade that was popular with visitors to Japan 100 years ago, and its refreshing sweetness is sure to soothe your tired body after a long walk.

*The cats are looked after by local people, so visitors are advised to keep a reasonable distance and not to feed them.
