Times have changed but the game with women hasn’t even tho I haven’t been there in a long time I know this cuz how I dealt with them still works now period here in any other country
I agree a month in Japan get full experience if you have the budget
So much to do and sightseeing
Women wise he is right they are shy but some are aggressive which will catch you off guard too. Your game on point by being yourself and being confident you can get back to your place same night. If you can learn simple phrases for compliments they will eat that up real quick and be really into you.
A lot of them do speak English but play dumb not speaking too see what u day and how you act keep that in mind.
Have your money right cuz it’s expensive there especially clubbing if u don’t pay attention.
Them ramen shops tho

Tokyo, shinjuku, shibuya and roppongi good places to go shopping and bar hopping
Yokohama also nice to go too
There is more but I’m driving
