Yes, there are still some shops in Japan running OS/390. It's more
expensive to do that than it is to run z/OS, so it's changing at a good
pace.

There are myriad reasons why that is so, as anyone who knows Japan knows.
Some of those reasons are changing now.  It's not a phenomenon unique to
the mainframe.  Japan tends to be a bit behind much of the rest of the
world in software versions on all platforms when looking at the whole
marketplace.

That said, there are some extremely cutting edge customers in Japan.  We
have lots of WebSphere Application Server for z/OS, at the new versions,
installed in Japan.  Of course there's plenty of IMS V9, CICS 3.1, DB2 V8,
etc., and they're all growing fast.  The new models (System z9 EC and BC)
are bought as quickly as anywhere.  Linux adoption has been incredible, and
I believe the two largest (most IFLs) mainframe Linux installations in the
world are in Japan.
