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!
Buying tickets on KKDay was very convenient. Overall, the experience was quite good. There were food stalls, giving it a summery feel, and most of the people there were locals, which was really nice! The fireworks, synchronized with the music, were rhythmic. However, since I don't understand Japanese, I couldn't understand a lot of what they were saying. Also, the fireworks weren't continuous; they were in several parts. It wasn't as exciting as I had imagined, and there were a lot of insects while waiting for the bus before leaving 😂
