Help Identifying jersey

[minnesotabats]

Can anyone help me identify this jersey that I just picked up at a local estate sale? It appears to be a jersey from the Nankai Hawks. It has a 63 jock tag at the bottom and a #44 on the back. It has a Kubota Sporting Goods tag on the inside top. I have included photos to see if anyone can help me determine what I have here. Is it a game used jersey and if so, is it from 1963 and finally who wore #44?

Appreciate your help in advance.

Thanks.
