The Tohoku Region, located in northern Honshu, is one of Japan’s top spots for a summer getaway. Located in Towada City, Aomori Prefecture, at the northernmost tip of the Tohoku region, is the hot spring village of Oirase Keiryu Onsen.

Why It’s A Great Summer Retreat:
Towada City and the Oirase Keiryu area maintain a cool climate year-round, making it a popular summer retreat. During this season, the Oirase Keiryu stream is surrounded by vibrant greenery, with sunlight filtering through the trees for a picturesque landscape. The pristine air and water, refreshing river, and abundant nature make for a tranquil environment rich in negative ions, offering instant relief from the summer heat.

This hot spring is known as a “simple hot spring,” referring to its low-stimulation properties, allowing anyone to enjoy it with ease. Given the harsh winters of the Tohoku Region, the hot waters of these springs gradually heats the body to its core, providing lasting warmth even after your soak.

When imagining a summertime hot spring resort, Oirase Keiryu Onsen is the first place that comes to mind. I always recall the unforgettable beauty of its lush greenery and the soothing murmur of the streams as I walked along it during my last visit in the early summer.

At that time, the Lake Towada Festival was also under way, leaving me with wonderful memories of watching the fireworks up close. Spending the day in the natural surroundings, followed by a leisurely soak in the springs while marveling at Oirase’s beautiful nature, is definitely one of the most relaxing experiences of my life.

It is no exaggeration to say that Kusatsu Onsen in Gunma Prefecture is the most famous hot spring in Japan. As of 2023, Kusatsu Onsen will have topped the list of “100 Best Hot Springs in Japan” for 21 consecutive years, a ranking determined by the votes of travel agencies. It boasts the nation's richest supply of spring water and is included amongst Japan’s top three springs, alongside Arima Onsen in Hyogo Prefecture and Gero Onsen in Gifu Prefecture.

Visitors can also enjoy touring around Sai-no-Kawara Park, located at the heart of the onsen resort. Here they’ll find a bubbling spring field where mineral deposits are harvested, and lots of springs dotting the entire area.

Why It’s A Great Summer Retreat:
Kusatsu Onsen is located at an altitude of 1,200 meters above sea level, offering a cool climate of at least 10 degrees Celsius lower than around central Tokyo, depending on weather and season. It may even reach cooler temperatures than at Karuizawa, another famous summer resort area.

The springs are known for their high acidity and mild stimulation, with potent sterilizing properties believed to be effective for various conditions like cuts, burns, neuralgia, bruises, diabetes, hypertension, and more. Legend has it that during the Sengoku Period, military commander Toyotomi Hideyoshi recommended Kusatsu Onsen's hot springs as a cure to Tokugawa Ieyasu, who had fallen ill at the time, underscoring its reputed health benefits. Even today, there are a number of inns that offer specialized "hot spring cure plans" to capitalize on these healing properties.

Kusatsu Onsen holds a special place in my heart, as a spot I've visited countless times in my life. Being so easily accessible from Tokyo, it’s been my family's annual summer vacation spot since childhood. Kusatsu offers a variety of activities unique to the area, from hanging around Sai-no-Kawahara Park and enjoying their onsen manju (hot spring buns) to soaking in the springs. I highly recommend it to people of all ages!

Yufuin Onsen is a hot spring resort located in Yufu City, Oita Prefecture, in the Kyushu region, at the foot of Mt. Yufu. Designated as a National Recreational Hot Spring Resort, it stands out as one of Japan's leading hot spring resorts, having consistently ranked as the country's top hot spring destination for 13 consecutive years as selected by a major travel information website.

Oita Prefecture itself is renowned as Japan’s "hot spring prefecture," boasting the highest number of hot springs and the largest volume of gushing spring water in the country, while Yufuin is blessed with approximately 900 of these natural hot spring sources, pouring out a staggering 38,600 liters of water per minute.

Beyond its hot springs, Yufuin is also known for its gourmet and local specialties. Time passes slowly in this leisurely town, surrounded by traditional Japanese landscapes and the majestic natural beauty of Mt. Yufudake, an iconic symbol visible from every corner of the town.

Why It’s A Great Summer Retreat:
Despite being nestled in a basin surrounded by mountains, Yufuin sits at an altitude of about 450 meters above sea level, higher than the city center. That coupled with the vastness of the foot of Mt. Yufudake contribute to cooler mornings and evenings, earning Yufuin the nickname “the Karuizawa of Kyushu,” likening it to the popular summer resort in Nagano Prefecture. Visitors can rejuvenate their spirits with a leisurely soak in these high-quality springs, while also indulging in the area’s natural coolness and delicious local cuisine.

Most of the springs here are “simple” or “alkaline-simple” springs, characterized by their clear, colorless, and smooth-to-the-touch waters, akin to a natural lotion. Visitors can easily enjoy these soothing springs not only at the local inns, but also at the public bathhouses scattered around town.

As a passionate hot spring enthusiast, I highly recommend the hot spring resorts of Oita Prefecture. Yufuin Onsen is a personal favorite for the exceptional quality of its hot spring water, which never fails to leave my skin feeling incredibly smooth and rejuvenated. Yufuin is also home to numerous nearby sightseeing spots, many within walking distance, along with many luxury hotels, making this place my top choice for a self-indulgent getaway. Whether traveling solo or with friends, Yufuin Onsen promises to be a fun and relaxing retreat!
