The most interesting etiquette in Japan

Here's what our Japanese and culture teacher Mrs. Sato taught us about japanese manners. all the students that were in Japanese and culture did the same assignment. We were split into different groups. each group chose which manners they wanted to cover in their video. the First day we had to pick a director, our director was Hana because she did a lot of acting.  our group agreed that we should chose Hana. I think Ken M had the second most  difficult  because he had to act like a student that didn't know about the Japanese manners. There are always right ways to do that manner and there is informal way of doing each of the manners.
Here are some examples that we included in our video:
Don't walk so slowly in Japan because its very rude.
Jesse told Ken that he should walk more quickly. Its often quite common to do when people are in a hurry.
Don't  talk on the phone when you are on public Transportation because it will disract others that are around
Don't talk so loudly when you are on the train because it will desract others that are around.
Its quite common in Japan for  people to greet other people even if you don't know them.
When you enter a building in Japan you have to take off you shoes Some places where are  School buildings,  houses, temples and shrines. but on specific example is the gorcey stores department stores
