If you want to visit attractions that are relatively far away but are worried about the long journey, then a day trip by chartered car is a good option.
This travel pass is a great deal! The round trip to Karuizawa plus a reserved seat on the NEX train back to Narita Airport is well worth the price. It also allows unlimited access to JR stations, so you don't have to worry about getting around. 😜 Very convenient!
The ropeway ride was shrouded in clouds, so we couldn't see anything, but when we arrived at Senjojiki, the sky was blue. We could even see Mount Fuji beyond the sea of clouds on the Alps side. We walked around the Senjojiki cirque, and although there was still a lot of snow and it wasn't a flower field, we were able to see some amazing scenery. I'm glad I thoroughly researched my equipment and clothing beforehand. The ticket office wasn't crowded due to the time of year, but thanks to the ticket reservation, we were able to move around smoothly.
