WW2 Japanese Good Luck Flag - Translation and Authentication Request

[WW2USCollector]

Hello! Could I was wondering if anyone here could authenticate and please translate this WW2 Japanese Flag? I'm curious to see what the writing says, and I also wonder if the flags recipient is listed.

Here's a couple more detailed photos of the front and back

The phrase 祝武運長久 (good luck in battle) is written in a couple of places on the flag. It is a very common phrase seen on flags like this. Also 祝出征 (congratulations on deployment) is written in a couple of places. 虎 (tiger) is written in a couple of corners. Most of the rest are names. Looks OK to me, but unfortunately I can't find the name of the recipient, which a lot of collectors like to see on the flag.

And the other large character to the right of the red disk is 魂 (tamashii) which means "spirit", but it is written in a slightly unusual way.
