The second one is listed in Benelux Revenues by Barefoot. It was issued in 1942 and is what the Dutch call a plakzegel, a tax stamp that needed to be attached to any document to make it legally binding. The Japanese just continued on with the existing system.

The second one is a Japanese occupation revenue for Netherlands Indies, Sumatra to be precise (name written in Malay: Soematera).
About the first one I can't say anything except that it is from Israel, but you knew that already of course :-) It might be a local forerunner from just before Israeli independence.
