Unusual US (?) Canvas Webbing Belt; "Made in Japan" tags

I bought all this today at a swap meet for the ridiculously low price of $4.

It looks like US webbing from WW2, but it had some strange features:

For one, the belt has no top or bottom rows of holes and only a single middle line of holes for the width adjustment hook. The belt has no markings.



Attached to the belt (very poorly) by its metal hanger through 2 of the holes was this canteen.


The canteen appears to be aluminum and has "JAPAN" stamped into the metal at the bottom. The canvas canteen cover has "KIFFE Japan" on the back.



I also picked up these pouches which were sitting nearby and have "Made in Japan" on their tags on the back.





What exactly did I just buy?

1960's commercial hunting/camping gear made from US pattern equiptment. At least the belt(to a point), canteen, and cover are. They also made a knock off cup. the other pouches are for mess utensils, raincoat, shells, really anything you can shove in them. kinda knpck off carlisle pouches.
