Concept
Japanese mobile phone culture
Summary
In Japan, mobile phones became ubiquitous years before the phenomenon spread worldwide. In Japanese, mobile phones are called keitai denwa, literally "portable telephones," and are often known simply as keitai (携帯).
A majority of the Japanese population own cellular phones, most of which are equipped with enhancements such as video and camera capabilities. As of 2018, 65% of the population owned such devices. This pervasiveness and the particularities of their usage has led to the development of a mobile phone culture, or "keitai culture," which especially in the early stages of mobile phone adoption was distinct from the rest of the world.
Japan was a leader in mobile phone technology. The first commercial camera phone was the Kyocera Visual Phone VP-210, released in Japan in May 1999. The first mass-market camera phone was the J-SH04, a Sharp J-Phone model sold in Japan in November 2000. It could instantly transmit pictures via cell phone telecommunication. The J-Phone (Stylized as 写メール, which stands for Photo-Mail) model not only included a camera, but also the function to send photographs via messaging or e-mail, which made the phone extremely popular at the time. Technologies like 3G mobile broadband were common in Japan before any other country.
Some of the main features of a mobile in Japan are:
E-mail
Configurable databases
Phone and address books
Alarm clocks and stopwatches
Live video feed via Piconet
