What are some good Japanese fairwoods?  Any in 4 wood 16 to 16.5 degrees?  

Exactly what I’m looking for , seems the best is the roddio baffy 

prgr egg mfd 16.5. never leave home withoit itstock shaft is good,YOUR shaft is oitstanding both from a fairwau and a tee. its tje best all rounder in my fleet of fwds

So many good JDM fairway woods!!  but I do highly recommend the Jbeam GFW.   Slightly larger than your typical fairway wood with driver like feel and pop to it.     I am absolutely loving my 13deg ... easy to hit off the deck even with the lower loft.  I also have a Modart 14deg FW which is smaller but also shallower and the 455 steel face provides an almost spongy feel to it.  

Crazy Full Ti FW is another good obe.  Very hot face, great looking at address and mid-face height. 

Modart comes in 16 deg and Crazy comes in 15.5.
