This is the first time we have ever seen or offered a complete set of single signed baseballs of all Japan Pro Baseball players who amassed 500 homers or more in their careers. Here's the list:

Rank Name HRs Years Active
1 Sadaharu Oh 868 1959–1980
2 Katsuya Nomura 657 1954–1980
3 Hiromitsu Kadota 567 1970–1992
4 Koji Yamamoto 536 1969–1986
5 Kazuhiro Kiyohara 525 1985–2008
6 Hiromitsu Ochiai 510 1979–1998
7 tie Isao Harimoto 504 1959–1981
7 tie Sachio Kinugasa 504 1965–1987

Naturally, all are Japan Hall of Fame members, with the exception of Kiyohara who will become a member after being retired for several more years. Additionally, all are eligible for Golden Players Club membership, as each totaled more than 2,000 hits in his career, with Harimoto being the only player in Japan Pro Baseball history with over 3,000 hits and 500 HRs. The balls are pristine and the signatures are bold.

Oh has signed a Golden Players Club ball, Kadota and Ochiai signed Official Japan Pro Baseballs, and Yamamoto and Kinugasa signed Official Hiroshima Carp balls, with the others signing ordinary baseballs. Nomura, Kiyohara and Harimoto included significant additional annotations, along with their signatures, with Harimoto writing the number of lifetime hits he achieved. Kadota was the only one of this group to sign his baseball in both Japanese and English. Nomura, Yamamoto, Kiyohara, Ochiai and Kinugasa included their uniform numbers. The Kadota and Kiyohara balls may have been signed during their active playing careers. The others signed after retirement. All are signed in black marker. This is a hard-to-obtain set of single signed balls.

Size: All are regular baseball size.

Condition: Autographs--10 out of 10. Balls--10 out of 10.
