What did I learn during my first time in Japan (Tokyo, Osaka, Kyoto, and Kobe)  and Korea (Seoul)?
-Shogun was right.  We are barbarians compared to them.
-You are given a hand towel/napkin any and every time you order food/drink. 7-11, Omakase, street food, restaurant, doesn't matter.  Clean your hands before eating.
-No one jaywalks or crosses the street if the light is red.  Then when it turns green, birds chirp.  Crosswalk posts have little speakers.
-I did not hear ONE SINGLE CAR HONK the 2 weeks I was there.  Blew my mind.
-In the same vein, the subway is dead silent.  Chuckled internally remembering the wild shyt I've seen/heard in the NY subway
-They got umbrella sharing.  Couple of coins, pick up an umbrella, drop it off at the next spot when you're done.
-Was with a Latina chick in Seoul and we got the foreigner treatment coming out of the Lotte Sky tower.  4 available cabs drove right past us to pick up Korean passengers.  I asked her if they had cancel culture, or prog, anti-racist campaigns and she said they laugh at that shyt.  "The Koreans, Chinese, and Japanese all hate each other.  What does that leave for the rest of us?"
-Shinkansen bullet train.  JR rail.  Light years ahead of our bullshyt Amtrak and Brightline. 
-They DGAF about Americans or the English language.  Service staff will talk a mile a minute in their language and if you don't know it, that's your problem.
-In general, Japanese women are ironing board flat.  Koreans have a bit more thickness (not hard compared to J-chicks).  Can count the number of decent asses I saw on one hand.
Travel brehs
Layover in Instabul.  Turkish Airlines has this touristanbul where they pack you into a bus to drive past some sights.  Airport is a good hour from the city.
