Yes, of course. My point is that it’s not as serious as some people make it seem to be on YouTube for example. It’s just a matter of common courtesy to try not to be loud, that’s all. But, most importantly, 空気を読む as you said.
Even though I already knew this, because we are so used to everything being shown in non-military time in America as you mentioned, I did reserve a Shinkansen ticket for the wrong time, lol. Thankfully I had the JR Pass (RIP), so I simply took the next train and went to the non-reserved seating car. No money lost.
BTW, in case someone reading is wondering why I wrote (RIP) next to “JR Pass”, at least last I heard, the JR Pass is no longer as economical for tourists as it used to be before October of last year. I’m not sure what’s the status on it as of today, but that’s my current understanding. IIRC, I believe the prices were increased to the point of it being more economical to simply buy tickets as you need them (unless you’re gonna be traveling a lot). Someone correct me if I’m wrong.
Anyway, moral of the story, be mindful of those military times. If you’re not used to them, they might get you, especially given that some places require reservation.
This video pretty much sums it up:
She has tons of shorts for pretty much any situation if anyone wants to check them out before traveling to Japan. They’re spot on.
