51. Crowded trains
Crowded trains can be a big culture shock for some people. However, many visitors find it's not that bad. It's important to avoid carrying big bags on a crowded train — this can be a real nightmare. If your schedule is flexible avoid rush hour. Otherwise, Japan has an excellent baggage delivery system called takkyubin. It's cheap, fast and reliable.
52. Noodle sandwiches
There are some pretty wild snacks available at Japanese convenience stores. Whatever you do — don't try noodle sandwiches (yakisoba pan). They're even worse then they look.
53. Slipper dangers
When you enter a Japanese home or a room with traditional tatami floors you need to remove your shoes.Often, you'll be provided slippers to wear. When you go to the restroom you swap slippers (to special toilet slippers). It's important to remember to remove the toilet slippers when you leave the restroom. Wearing toilet slippers outside the toilet is the most embarrassing thing you can do in Japan.
54. Head Clearance
Head clearance in old (and some new) structures can be low. Watch your head.
Taxes in Japan were once assessed according to the dimensions of the front of your house or store front. Houses and businesses quickly adapted — building tiny street-facing façades to much larger interiors. Thus the small doors on historical buildings.
55. Loudspeakers
Good morning it's the government, did you know that today is clean your house day? Municipal governments across Japan use loudspeakers to announce seemingly trivial things. You may find that it's charming after you've been in Japan for a long time.
Politicians also use loudspeakers for their campaign. There always seems to be an election going on.
56. Engrish
You know that English teacher you had who was a real stickler for grammar? She/he doesn't like Japan.
57. Everybody takes holidays at the same time
Japan has more holidays than any other country. Many of these are mega holidays — business essentially shuts down and everyone goes on vacation.Mega holidays include New Years, Golden Week, Obon and in some years Silver Week. Needless to say these aren't the best times to travel in Japan. Everything gets more crowded and expensive.
58. Peace
Japanese people commonly make a peace sign when the pose for a photograph. Tourists to Japan do it too. At first it's done mockingly. However, it quickly becomes addictive.
59. Too many black belts
There are dozens of Japanese martial arts including Judo, Karate, Kendo, Kyudo and Aikido. There are quite a few martial arts experts walking around (who went to a better school than McDojo).
60. Yakuza
As a tourist it's unlikely you'll see Yakuza. If you do they'll likely ignore you. They have better things to do than to pick on tourists. That being said, a yakuza could certainly ruin your day.
