The best thing about them is they look really cool
And they go REALLY fast
I went on a shinkansen six times, a normal train 10 times and a teeny local train five times.
The bullet train was great for getting to places quickly. But… they’re not very big. Not sure if it’s possible to tell from pictures, but they are q low to the ground. Also the windows are on the small side. So the view is not great, especially when the train is travelling at just below the speed of light.
I hate to say it, but I prefer the French TGV
