The 500 Series Shinkansen is, in my opinion, the best looking of these super fast trains. Unfortunately they are stuck on “slow” Kodama services now, so I’m unlikely to catch one on this trip. However, I did spot the Neon Genesis Evangelion liveried train as we raced through Himeji station, then got a chance to properly admire one at Shin-Yamaguchi.
The Chugoku region of Japan is another favourite and it’s a pity not to have the time to explore it further this time. Preference on one of the KiHa 120s that run through the rural lines.
