A large part of understanding the perspective of Japananese society is understanding social etiquette and expectations. The basis of this is manners and respecting the people around you. Because Japan is an island country, saving energy and recycling is a big part of life there. Finally, Japan is the cleanest place I have ever been, especially in terms of trash and keeping streets and sidewalks clean.
I just visited Sapporo this past weekend, which is the biggest city in Hokkaido (the big northern island that looks like a manta ray to me). This means that I went on more public transportation the past three days than my entire time in Japan--planes, trains, buses, and the subway. On public transportation, I can use my phone as long as it doesn’t make sounds, but it is unacceptable to use a phone to call someone because it is considered rude to other people sharing the space. It is also discouraged to talk loudly with the people around you, even in person. Coming from the U.S., this wasn't something I had really considered before as, unless it's really late at night or early in the morning, there is no standard for being quiet on public transportation.
