Japanese/American Currency

The notes in Dutch ("de Japansche Regeering") were intended for use in what is now Indonesia. Prior to the Japanese invasion Indonesia was a Dutch colony, the "Netherlands Indies". The Japanese name for their newly conquered territory was "Shonan", meaning "great eastern land"; the block letter "S" on these notes stands for Shonan.

The notes in English denominated in Dollars with "M" block letters were issued for use in Malaya, formerly a British colony. Notes in "pesos" are indeed for the Philippines.

Basic info about the issuing and usage of JIM during the occupations can be found in this old thread.

JIM notes are generally very common. The scarcest are the "Oceania" series, denominated in pounds and shillings, for use on New Guinea and the Solomon Islands.

Some of your notes appear to have been taped? That will dramatically reduce their value.

No, that is a plastic jacket that the bills are in. There is no tape on the bills. There all in real good shape. You can slip them right out of the plastic from one side. I didn't though because I didn't want to handle them.

Australian servicemen brought them home too. JIM (Japanese Invasion Money) is quite common, I remember it by the shoe box full as a kid after the war. It has I recent years become quite collectable. Arlie are Slaubach wrote a very informative booklet on the subject in the 1960's.
