Japanese Keitai etiquette

We call it "manner mode" for silent mode on Keitai -mobile phone- in Japanese.

Japanese are very conscious about if we are not disturbing other people. Thus, in the train, we're not supposed to talk on mobile phone. This is also due to a medical purpose that the electronic wave from mobile phone might affect a heart pacer.

Since we cannot talk on the phone in the train, writing keitai-mail (email) is very popular. It's different from sms as they don't use tel. no.  I noticed 5 out of 6 seated passengers in front of me were writing something on their keitai. We are so obsessed with kaitai..
