The service is based on Kimekuru, a cellphone service that automatically distributes images, text and other content to compatible cellphone handsets at preset time intervals.
The Kimekuru service enables users to choose from 16 types of content from three genres, including news, hobbies and entertainment. The service covers 350 stores located in Tokyo, and Hitachi plans to expand the service area gradually.
Currently provided on a trial basis for four handset models from NTT DoCoMo and au, the Chizukuru service will be fully expanded to cover 28 models from the two carriers. Hitachi aims to sign up 500,000 users by 2008.
