Senko Onsen

After my hike up Mt. Azumaya, I searched for an onsen as I always do and stumbled upon Senko Onsen. The unique name and its historical ties to the Sanada clan caught my interest, so I decided to head over. Just as I was getting close, the road suddenly narrowed, and I had to navigate a sharp curve. I found a building that felt more like a cozy traditional inn than a simple day-trip bathhouse. There were only about three parking spots, but luckily, one was free!

Hishino Onsen – Yakushikan

After finishing my hike to Mt. Kurofu to see the ‘gateau chocolat’ Mt. Asama, my main plan was a day trip to Takamine Onsen, a ‘lamp inn.’ But unfortunately, their day-use hot spring closed much earlier than scheduled that day. So, I started looking for another good onsen on my way home and stumbled upon Hishino Onsen.

Uminokuchi Onsen – Yumoto Hotel Izumi-kan

After finishing a day hike up Mt. Kobushigatake, I looked around to see if there might be a good hot spring near the trailhead at Moukidaira. Unfortunately, there were no onsen nearby, and even heading down the prefectural road toward Kawakami or Nobeyama didn’t seem very promising. Just as I was starting to give up, I spotted Uminokuchi Onsen Gensen on Google Maps. It looked amazing—but some posts said it had already become a ruin. Still, on closer inspection, it seemed that a nearby inn called Izumikan was offering day-use bathing, so I decided to check it out.

Mochimune Minato Onsen

I had some errands to run and found myself back in Mochimune for the first time in a while. My grandparents used to live nearby, so I often visited the area as a child and have fond memories of playing in the ocean at Mochimune—it’s a nostalgic place for me. While there, my family, who had arrived ahead of me, suggested we go to the local onsen. I asked, “Wait, there’s an onsen here?” and they replied, “Yeah, it’s been around for quite a while now.” I was surprised—I’ve been back to my grandparents’ house several times in recent years, but somehow I never knew about it…

Yuya Onsen – Horai Yuyu-Arena

Yuya Onsen in Shinshiro, Aichi, is a historic hot spring said to have been discovered 1,300 years ago by the ascetic monk Rishu Sennin, who founded the nearby Hōrai-ji Temple. Its source, called “Hōekisen,” is famed as a therapeutic spring believed to cure all kinds of ailments. I came across Hōrai Yuyu Arena and decided to give it a try right away.

Nagato Onsen – Yasuragi-no-Yu

On the way back from a hike to Mt. Utsukushigahara, I did what I always do—look for a good hot spring. That’s when I came across Nagato Onsen Yasuragi-no-Yu, known for its therapeutic bōshō-sen (sodium sulfate spring). Conveniently located next to a roadside station, it seemed like an easy stop.

Anan Onsen – Kajika no Yu

I occasionally visit Iida and Komagane in Nagano for hiking and sightseeing. On my way back, I often take the local roads south to Hamamatsu, stopping by roadside stations along the way. One of the hot springs I had always noticed but never visited was Anan Onsen – Kajika no Yu. I had been curious about it, but I usually preferred soaking in a hot spring closer to Hamamatsu. This time, after my cycling trip, I decided to finally stop by and soothe my tired body.

Sessokyo Onsen Kaikan

Today, I decided to do a round-trip eBike ride from Senzu Station to Ikawa Station, following the route of the Ikawa Line, a charming little red train that runs along the stunning Ōi River scenery.

While taking photos at the famous Oku-Ōi Kōjō Station viewpoint, I posted one on SNS. My colleague recommended a nearby hot spring facility, so I decided to stop by on my way back from Ikawa.
