The armband is made in India by Shah as mentioned. They made many uniforms and other items for the Indian and British Army during the war.
The rank and name tab, or pocket hanger, is typical of what was worn by Japanese soldiers in the later part of the war, when rank was normally not worn on the collars in the field anymore. They were field made and typically had a name, rank badge and often unit codes (which this example does not have), and or colored bits of cloth which indicated the arm of service, in this case green for medical.
They were made in all sorts of shapes and sizes and either had pins or button holes for easy removal in battle, and were usually worn on the chest pocket and sometimes on the side of the field cap.
I believe it is most likely from Burma, although it could be from elsewhere as well.
