Frequently Asked Questions
Is the entire journey from Tokyo covered by the Japan Rail Pass?
No. The JR Pass completely covers the Limited Express train or Shinkansen components up to Naganohara-Kusatsuguchi or Karuizawa Stations. However, the mandatory connecting local buses into Kusatsu town are operated externally and require separate cash or fare payment.
Are tattoos allowed in Kusatsu Onsen public baths?
Many public baths maintain traditional restrictions against visible tattoos. To enjoy the thermal waters worry-free, travelers with ink should book a private family bath ('kashikiri') directly at their ryokan hotel.
