The use of mobile phones to make calls on public transport is frowned upon, and messages asking passengers not to make calls and to switch their phones to silent mode ("public mode" or "manner mode" in Japanese) are played frequently.

(see also Shift JIS art) One very distinct form of writing is called 'gyaru-moji ('gal characters' named after the fashion style 'gyaru' or 'gal' because the people of this fashion style are the ones who often use this kind of lettering).

By splitting the characters into alpha-numeric characters, it extends the possible over-all length of the message.
