When we were shopping for a used press brake about two years ago, I believe we found that while the Komatsu was still made and serviced in Japan, it was no longer marketed in the US. If I recall correctly, they had no support for existing machines stateside.
Someone else may have better info.

I do not think that the above post is the case. We recently sold a used Komatsu mechanical press that ended up not being the right selection for our application and considered buying a new Komatsu servo press. We ended going to a Greenerd hydraulic press because there was uncertainty that the servo was going to accomplish what we needed.
Even though the Komatsu mechnical press did not work for our particular application, I found that the press was a top end piece of a equipment and that the level of service and support from Komatsu was second to none.
As far as I know Komatsu is still in operation in the US and can be reached at:
