I had one of my most fun adventures ever with Tsuyoshi. We went mountain biking on Mt. Sasayama. Tsuyoshi knows the best roads, viewpoints and descents. It was really challenging, but also extremely beautiful. It was a place I would have never found without Tsuyoshi. He also took care of our bikes and had a pick nick prepared on top of the mountain!
I can definitely recommend Tsuyoshi as a guide. He knows the area very well, has a lot to tell about the local history and culture and he takes in mind your physical possibilities. And he is super friendly!
