So you need to find a source of both male and female parts to make the 
extender cables?  What volumes?

Very likely.  The Japanese prefer to use locally sourced parts.  You need a 
short-list of Asian region companies that were making multi-pole PCB 
connectors 30 years ago (>.<)

Maybe JRC or Asahi Kaesi used to make connectors.  Are there any Japanese 
members on this list that might be able to shed some light?

If you just need a small number of these connectors I wonder if you could 
bodge something using a tiny non-standard build thickness PCB with some 
Molex or Samtech contact inserts soldered directly onto the top and bottom 
surfaces at the correct pitch?  Either blades, or receptacles from some 
other connector series that mate sufficiently well with the contacts of the 
unknown connectors.  It's a last resort, not very pretty, and wouldn't have 
the plastic shell to provide retaining force etc.  but you could track the 
surface mount pads for the contacts out to a 0.05" pitch or whatever for 
ribbon cable, or an IDC connector or whatever.

Sorry I can't be of any more help,
