Are the Japanese on the move (travelling, commuting) more than people in other countries?

Everyone knows that Japan has the world's highest rates of rail travel. But Japan also has some of the world's busiest domestic airports, busiest domestic flights, and very high rates of car ownership - higher than most European countries. Whereas in other countries, high rates of rail travel translate to fewer cars and vice versa. The only logical conclusion to me is that the Japanese are on the move more than people in other countries. Do you agree with this conclusion? And what are the reasons for this?

I'm flying by myself for the first time in a week and I'm quite nervous - 2

So i'm 17 I have flown a few times before 5 times (well 10 if you count there and back) the last time was over a year ago, this isn't the first time flying without my parents as I went on a school trip but this it's my first time going to the airport by myself checking in, going through security, getting my gate boarding etc I have flown from this airport 4 of the 5 times so i'll probably know my way when I get there but as of now I can't think of a what to do when I get there its dublin airport if anyone has been there I use to not care too much about flying but lately now that I have to do it all by myself I'm quite nervous but I go in and out about being kind of scared and then other times I'm kind of came about it, I don't usually have seats beside who I'm flying with and the flight is only around 2hr30 mins( the longest i've been on is just over 3 hours) so I'm not sure why I'm scared/nervous so can anyone help any tips of what to do how to calm myself/ stop overthinking it? Anything at all that will help thank you so much!
