Most of them have celluar phones. Our guide told me that they sometimes sit in class and send e-mail to each other with the phones. They can send messages to each other by typing under the desk with their fingers. The teenagers in Tokyo are talking on the cell phones all of the time. Most business people in Japan have cell phones.
People also like to use fax mail.
Not many schools here have the internet. The junior high had one lab with 30 computers with internet access but that was it. The students do not have many opportunities to use computers in their studies. But still they are busy. One of the things that they study that is different from our school is Japanese calligraphy.
