Two of the most picturesque onsens in Japan are located in Gunma Prefecture, a short trip from Tokyo but seeming like worlds away! Let's take a look at these scenic hot spring resorts and what makes them stand out as great destinations! 

Minakami Onsen, located in the heart of Gunma Prefecture, is a popular hot spring destination known for its diverse range of bathing options and stunning natural scenery. The area boasts over a dozen separate hot spring sources, each with its unique mineral composition and therapeutic properties. Minakami Onsen itself is a bustling town centered around numerous hotel complexes, offering a mix of modern amenities and traditional Japanese hospitality.

The hot spring waters in Minakami are renowned for their clarity and the lack of strong odors, unlike some other famous onsen areas in Japan. This makes them particularly appealing to those who might be sensitive to the sulfuric smell often associated with hot springs. The mineral-rich waters are said to be beneficial for various ailments, including muscle pain, joint stiffness, and skin conditions.

The centerpiece of Takaragawa Onsen is the Osenkaku ryokan, which offers visitors access to four large open-air baths. The largest of these, known as "Kodokara," can accommodate up to 200 people and measures over 300 square meters. 

What's particularly unique about Takagawara Onsen is that three of its outdoor baths are mixed-gender, a rarity in modern Japan. For those who prefer more privacy, there is also a women-only bath available.

The resort welcomes both overnight visitors and day visitors. Open 24/7, taking advantage of the rotenburo at night or in the early morning when the local wildlife quietly awakens
