When you enter a japanese house there is a small area, called a Genkan which is right in front of the door. Even though the Genkan is inside a house it is considered outside and is an area where people take off their shoes and put on shoes that are offered by the hosts the house. It is a good manner if you point your shoes to the door when you take them off.
Taking A Bath
Japan has many differences even in their home they also have differences when taking a bath. In Japan the main point of taking a bath is not to clean yourself but to relax at the end of the day. A Japanese bathroom is usually split into two one room for you to undress your clothes and has a sink the other room has a bathtub and a shower. When bathing in a Japanese style you should rinse your body out of the bathtub using a sink and then soak your body In the bathtub and relax for a couple of minutes in nice hot water.
Visiting Historical buildings
When visiting historical buildings such as temples, you should wear shoes that are easy to take off and put back on such as slippers because you may be forced to take it off and on again. Additionally you should make sure that your socks don't have any holes and are neat.
Eating and Drinking in Japan
There are many manners and situations in Japan when you eat and drink. In Japan not finishing your food or meal is not disrespectful or rude, but is a sign to the host that you want to be served with a different meal. When you finish your meal especially the rice it is also a sign to the host that you are satisfied and do not want to harp enough more. In some foods like soba or ramen noodles it is appropriate to slurp but some food like westerns pasta should not be slurped.
Bowing is the most well known etiquette outside of Japan. Bowing is very important in Japan and children learn how to bow in a young age. Bows should be done with your back straight and your hands at your side and your eyes down. The deeper and longer you bow to a person the more the person feels stronger and more respected.
Automated Rotary Parking
One cool thing I found was that Japan's the first Automated Rotary Parking Systems in the world. Japan’s parking invention allows many cars to be parked in a small area that could fit four to five cars. This can help drivers save time when looking for a parking and save fuel.
