8 typical things about Japan !

1 - Why is everyone wearing a Surgical mask ? Are they all sick ?

Japanese wear surgical masks to avoid bacteria, but usually they wear them because he/she is already sick and wants to protect others. If you have a cold or catch one in Japan, you should wear a mask as you travel. You can purchase them in any Konbini or simply a 100 yen shop like Daiso. You can get some that are customized as well, personally i wore the black one makes me look like a Ninja !
Ninja ! Told you !

2 - Why is everyone sneezing and not blowing their nose ? 

Japanese people think it's disgusting to blow your nose, and some of us caught a cold and so we were wondering what are we supposed to do ?
Blowing your nose in a paper tissue is okay, judging by my japanese friends, you just have to turn away from someone. Or which is best is to blow your nose in the toilet. 
"The truth is more simple - it's considered extremely disgusting to blow your nose with a cloth handkerchief. When a Japanese person sees a handkerchief shaped piece of cloth, they will assume that it's for wiping off sweat from the face, or if it's a great big one they'll assume it's a cloth to put your lunchbox "
Luckily, we do not use handkerchief, we think it is kind of "oldschool" anyway :)

3 - The country is super clean, how japanese do that ?

Cleanliness for japanese people represent purity. The Japanese take great pains to keep their cities clean. Even if there is people employed by the state to clean up, it is also not uncommon to see groups of retirees meeting up on mornings armed with garbage bags and pick-up sticks. Even if the city is super clean, there is very few trash cans you have to hold on to your garbage for some time !
We were right in the middle of the crossroad of Shibuya...

4 - It's crowded, and people are everywhere, but how does the city is so quiet ?

Japanese people act for the good of the group, they put the need of the group before their own. So blabbering loudly in public can annoy some. They advised us to use ‘indoor voice’ outside. For us French people, we are not accustomed to it because we often speak loudly.

5 - So technological toilet ! 

Told you cleanliness represent purity ? Well you can observe it also with the japanese toilets, they are generally more elaborate than toilets in other developed nations.

6 - They have so many manners and polite expressions, so how should I act ? I don't want to be rude !

Manners matter ! Yeah yeah ! That's right ! You should say thank you for nearly everything  in Japan! Smile and bow when you say it.
An arigatou is good for close friends, but if you talk to someone you don't know you should add "gozaimasu" > “Arigatou gozaimasu!”
There is also table manners, you can go on that website if you want to know more :

7 - Japanese and english...

In Japan, it is not common to speak english. But i assure you they are willing to help, not EVERYONE ! We encountered some people who were very rude even if it was their work to inform us, they were just mimicking the directions like we annoyed them... 
But anyway, mostly we always got what we wanted in every restaurants we went, got every infos we needed, even met japanese people with whom we friended... they speak the minimum english but it is enough :) So do not panic about that !

8 - Got sick in Japan !

We caught a cold there and so we needed drugs. We went to a pharmacy and asked for what we needed. And we were impressed on how expensive it was ! So prepare drugs from your country so you won't be surprised by any cold or anything in Japan ! If any of you are or go in Japan during winter, and during the starting of spring, well it's cold & windy outside but also in appartments so put your sweater on ! ?
