Japan industries have been using many mainframe computeres over 50 years. Day by day, especially in Finance, Manufacturing and Public area, mainframe computers are processing huge of transaction. Mainframe computer industy is one of the key industories.

But incredible, there are no public books, majority of IT engineers don’t know about mainframe computers. We are afraid each mainframe engineers like being put on isolated islands.
This is the reason why we put this site. Hopefully, this site will grow up to a mainframe community and here is “mainframe knowledge portal”.

Most of all articles are written in Japanese language, but if you want to tell something or notify something good for mainframe engineeers, please let us know. We will arrange as we can do, including translation into Japanese.

Cheers,
