Japanese MLB Players With No NPB Experience

Rikuu Nishida made his MB debut with the White Sox today.  Nishida was born in Osaka, Japan but played college baseball in Oregon for Mt. Hood Community College and the University of Oregon.  He was drafted by the White Sox in 2023 and has been working his way up their farm system ever since.

I think that Nishida is the seventh Japanese baseball player to make it to MLB without having played in NPB first but I'm not positive.  Part of the uncertainty is defining what "Japanese baseball player" means.  Does it mean being born in Japan?   That would mean that someone like Dodgers manager Dave Roberts, who was born in Okinawa to an American serviceman father and Japanese mother, or Lee Jung-hoo, who was born in Nagoya while his father Lee Jong-beom was playing for the Dragons, would count.  I'm not sure folks like that are what most people think about when thinking about "Japanese baseball players", however, so I'm going to go with "players who could reasonably be expected to hold a Japanese passport".

The six previous players by my definition are Mac Suzuki, Michael Nakamura, Kazuhito Tadano, Junichi Tazawa, Gosuke Katoh and Lars Nootbaar.  I'm a little iffy on whether or not Nootbaar has a Japanese passport but obviously he meets the definition of "Japanese" for the purposes of the World Baseball Classic.  I suspect Nootbaar would probably not want to let anyone know he's got a Japanese passport if he ever decided to play in NPB as he would then be subject to their draft rather than being a free agent (which is why Katoh was drafted by the Fighters despite being born in California to Japanese parents).

Four of these six players eventually played in NPB with Tazawa and Nootbaar (so far) being the exceptions.  Three of those four joined the Fighters oddly enough.  Tazawa had wanted to join NPB but was pretty much blackballed after spurning the league for MLB in the late 00's.  He had made himself available for the 2020 NPB draft but wasn't taken by anyone.

Here are NPB cards of the four plus a Japanese WBC card of Nootbaar:

2003 Calbee Series One #082

2006 BBM Nippon Series #S08

2013 BBM 1st Version #171

2024 Epoch Fighters Premier Edition #29

2023 Topps Samurai Japan #10

There have been a number of Japanese baseball players who started their professional careers in North America (but didn't necessarily make it to MLB) before ending up back in Japan with NPB.  I did a post on a bunch of them some years back (which included Suzuki, Nakamura and Tadano) but I don't know if I missed anyone or if there's anyone that's come in the years since then.
