Steer clear of public displays of affection, especially on the first date.
Choose the standard dinner-and-a-movie date, and you won't go wrong.
Would you like to know some Japanese dating customs?
Surely, you must understand their dating customs and traditions before going on a date with a Japanese.
I’m sure people can find exceptions to what I am putting forth as general rules. Additionally, I am a man, so all of my understanding comes from the perspective of a man.
Like most people from every nation around the world, the people who love their roots would like to keep the customs and traditions that their ancestors have passed onto them so that the next generation will keep them too and pass to the generation, and so on.
In general, avoid drawing attention to yourself or your date (no PDA's).
Be polite, follow the "ladies first" rule and brush up on your basic Japanese table manners before going out.
In Japan, most do no begin to date until sometime after high school, primarily due to the high demand on the students to get into a good college.
Parents typically will discourage any form of dating, and students will simply be entirely too occupied with school and studying to give it any legitimate consideration.
