When Japanese greet, they bow. When they see people they meet for the first time, or people who are familiar with them or anybody they meet, in many cases they bow. In foreign countries, there are many ways of greeting. When I visited France some time ago, I experienced the greeting in which people kiss each other’s cheek. And I was shocked by the close distance from others.
In Japan, people are supposed to bow as a greeting most of the time. So Japanese don’t have to touch anyone when they greet. And when Japanese bow, it is normal to have a certain distance from others. For such Japanese, the greeting style of western countries may be uncomfortable, I think. When they shake hands, their minds are calm, they still feel OK. But when they hug or when they kiss each other’s cheek, they feel that “it’s too close!”.
Japanese often touch and hold each other’s hands with intimate people like family members or lovers. But it’s rare they do it with people they don’t know so much, and it’s even more rare they touch people they meet for the first time. So there are many Japanese who care about the distance from others. For example, when Japanese talk to an unfamiliar person, and that person gets too close to them to talk, I think many Japanese will have the opinion that this person may not know how to keep his distance from others.

Japanese care about the distance from others, but the concept falls apart in the morning in the crowded train. In that situation, they are obliged to touch all the strangers around them. But it is for going to work. Only in crowded trains, they can’t afford to care about their distance.
