2023 Topps NPB Bowman Baseball Checklist

180 Base cards, three 24-card inserts and six autograph signers

2023 Topps NPB Bowman Baseball covers all twelve Nippon Professional Baseball clubs, filed in Topps's checklist archive as 2023 NPB Bowman Baseball. The official checklist names players in Japanese, lists 180 Base cards by team, and numbers each insert within its own list.

What's in the checklist

• Base: 180 cards, #1 野口 智哉 through #180 樋口 正修. Cards the checklist flags as rookie are marked RC
• Parallels: none are specified in the checklist
• Inserts: 1989 Bowman, Spotlight and Youth Culture, 24 cards each, each numbered 1 to 24 within its own list
• Autographs: six signers under サイン, including 大谷 翔平 (Shohei Ohtani) and イチロー (Ichiro). The checklist numbers them 1 to 6 within the list but doesn't show those as card codes, so no card numbers are given here

Key subjects

山本 由伸 (Yoshinobu Yamamoto, #5), 佐々木 朗希 (Roki Sasaki, #64), 村上 宗隆 (Munetaka Murakami, #100) and 浅野 翔吾 (Shogo Asano, #142, flagged rookie).

Grading considerations

Check centering, corners and edges, and look over the surface for print lines, dents and scratches, using angled light on any foil areas. Because Base and each insert share numbers like 1 to 24, match the card number, the insert design and the Japanese name on the card to the right list. A checklist establishes identity, not condition.

Scope: this page is a snapshot of the official roster as read on 9 October 2026, showing the 258 cards it lists. It does not claim complete coverage of every card, parallel or version produced. The autograph numbers 1 to 6 are the source's list numbers, not confirmed printed card codes. No parallels are specified, and the PDF says players, design and specifications may change.
