Business Summary

We develop and market package software, edit and publish books on computers and on general topics. One of our focus these days is to commercialize the results of the TRON Project and the T-Engine Project.

Such commercial offerings include T-Engine Development Kit--an open platform for embedded systems, Disk Shredder--a hard disk eraser software, and Chokanji --a BTRON-specification OS that runs on PC.

We continue to challenge new business and development of new products, pursuing the useful tools for each and every person, that is to say, "Personal Media".
