A paybook in the truest sense of the word. The cover has the same kanji that was translated by haru a few years back. Yours is id'd and has a few entries which is nice. What is really cool about this kind of booklet is it has space to write out which units the soldier belonged to exactly, beyond the larger divisional unit. Unfortunately, the units are named after commanders and aside (from what I can make out) from the unit code for what looks like the 2nd Division, sub units are unclear. This kind of pay booklet does pop up from time to time, although it seems like half of the booklets I have seen in the past were unissued. Hopefully someone can correct me on this, but I believe there were booklets for enlisted and others for officers. I have seen white colored pay booklets as well as blue covered specimens. Thanks for sharing.
