Grandpa Coin Collection - Part 3 of 4

Part 3

Thanks to SmartOneKg I was able to identify all coins for Part 3 and 4.  He graciously gave links for all coins in Part 1.  The only ones I cannot identify seem to be possibly the China coins in Part 2.  Those I believe are going to be a lot harder.

Any help here would be appreciated.  He was there post war so I would think the coins would be close to the 1940s but I have not been able to find any that match close to those dates.

 All five coins are from Japan ...

   I think they are the right ones, and dates range from 1938 to 1945 years.  

P.S. I don't see Part 4 of 4 or is that to follow ?

From other responses, I actually figured out all the coins in Part 4 before I had a chance to post it.  The only ones I am still having an issue with now is Part II.  I have been informed that the first one is from Japan but I have not been able to find it and I have also not been able to find the other two that have been identified as from China.  Any help there would be much appreciated.

Thank you very much for the identification of these!!!!
