Reliable Route Inn quality across the whole country. About a 5-minute walk from Hanyu Station, with a large hot-spring bath featuring free-flowing natural spring water.
Conveniently located near Ashikaga City and Kumagaya City. A Business Hotel with a rare natural Onsen with free-flowing hot spring water in the Saitama City area. Equipped with a sauna and more. We welcome you to a comfortable space to relieve your travel fatigue.
As the facility includes an Onsen, I was able to spend a very enjoyable and comfortable time. I heard the tuna is delicious, so next time I would like to take my time and enjoy the meals as well.
