Parillo's book does not have a listing of Japanese merchants.
I should have made things more clear in my posting. The excerpts are from S. Komimaya's Wartime Transportation Convoys History which I have in MS Word format on CD. As I said, I was given this by another researcher last year.
The document is broken into 3 files of approximately 1.08 megs each. One is a tad bigger. So it totals out to about 3.33 megs.
Anyone interested in Komimaya's work can PM me for more info.
