Any vintage Japan experts to help ID these 1931 signatures

[Topnotchsy]

I picked up a number of 1931 US Tour of Japan pictures and while the majority are signed by US players, a few are signed by Japanese players and personnel.

In a few cases, a name was identified, though a couple of signatures were not. I'd appreciate any help:

Picture 1: Signed by 4 people, 1 in Japanese. Label says, "Ito, Grove, O'Doul". I believe Ito is the one in Japanese and would love to know more about who he was. I struck out trying to find his name online and he's not mentioned in the book I have about the 1934 tour. I also would love to know who the 2nd signature is. He signed on a couple of these, but none are noted on the flip. Looks something like P. Hakumo" but not sure...

Picture 2: Signed by 3 people. Flip lists Grove and Matsumoto. Signature on the right looks like the signature in picture 1 that was not noted. I am pretty sure Matsumoto is Takizo Matsumoto who passed away in 1958 and was elected to the Japanese HOF in 2016.

Picture 3: Signed by 2 people. Flip lists T. Oshita and Herb Hunter. Haven't been able to find any info on Oshita

Picture 4: Signed by 1 person. Hisashi Koshimoto is listed on the flip. Died in 1935 and member of Japanese HOF.

Picture 5: Signed by 2 people. Atsushi Kono listed on flip. Other autograph matches the signature in earlier photos that is unidentified. Kono passed away in 1946 and is a member of the Japanese HOF.

Any info would be greatly appreciated!

About photo 3, the inscription says November 28, 1931, Koshien (stadium). There was a tour by the American team in November, 1931 which played several games at Koshien, though none on November 28. They were:

November 22 against Waseda University
November 23 against Keio University
November 26 against Kansai University

My guess is that Ooshita is from one of those universities, though I'm not sure which.

Thank you. The pictures definitely originated from the tour. With a bit of help I believe the names of the 6 Japanese signers are listed below. Have struggled to find any info to get a sense of their value though.
