NJPW 50th Anniversary Jacket

This is a really nice jacket featuring the NJPW 50th Anniversary logo.  A red NJPW 1972 tag is sewn onto the front left pocket as a nice touch.  New with tags.  This jacket is Japan sized 3L.  However, it appears to run smaller than the NJPW tracksuit size 3L that you might be familiar with.  I'd size this as a US Large.
