長野に住んでいながら、渋温泉という温泉の聖地について今まであまりに無知だった。
Even though I've been living in Nagano for three decades, I was totally ignorant of the existence of the onsen's sanctuary. It's Shibu Onsen resort.

今までの温泉といえば、日帰りか、宿泊、それだけ。基本的に家から日帰り温泉施設か宿泊施設の往復だった。
Onsen, in my memory, was a one-day trip or two-day trip with staying over. That was it. Basically, the trip was just between home and onsen facilities.

だが渋温泉は違う。旅館で完結しないのだ。
However, Shibu Onsen resort was different. Your trip just doesn't end there at the ryokan hotel you stay.

宿泊客は、こぞって温泉街に繰り出し、９つの外湯をスタンプラリーをしながらめぐるのだ。
Ryokan hotel guests actively go out and enjoy the stamp rally to complete stamps from all nine different onsen facilities called "so-to-yu".

これら９つの外湯をまわる間に狭い路地や、オシャレなお店などを発見して入ってみたくなる。冒険心をくすぐられるのだ。
Through those nine onsen facilities, you will find narrow streets and neat shops, which will stimulate your adventure mind.
