Source-derived summary

Tadahito Iguchi (井口 資仁, Iguchi Tadahito; born December 4, 1974), nicknamed "Gucci", is a Japanese professional baseball second baseman and former manager of the Chiba Lotte Marines of Nippon Professional Baseball (NPB).

As a member of the Chicago White Sox in 2005, Iguchi became the first fully Japanese position player to win the World Series, and the second Japanese-born position player to win the World Series behind Dave Roberts.

Early life and amateur career

Born in Tanashi, Tokyo, Japan as Tadahito (忠仁), Iguchi began playing in high school and after graduating in 1993, went to Aoyama Gakuin University where he distinguished himself by hitting the Tohto University Baseball League record of eight home runs in a season and winning the triple crown. He was a member of Japanese National Team in 1996 Summer Olympics that won the silver medal.

Professional career

Fukuoka Daiei Hawks

He was the first pick in the 1996 draft by Fukuoka Daiei Hawks.

In his debut year of 1997, he hit a grand slam in the first game of his professional career. He suffered a shoulder injury in the 2000 season and had a surgery which ended his season. After the season ended, he changed the Kanji of his first name to the current one (資仁). He recovered fully in 2001 hitting 30 home runs and leading the league with a personal best 44 stolen bases. In 2003, he hit over .300, had over 100 RBI and led the league in steals.

Editorial summary

This brief starts where responsible research should: with the source description of “Tadahito Iguchi” as japanese baseball player. Everything that follows is an evidence route, not borrowed authority.

Editorial reviewA productive starting point for separating a subject’s documented career from later reputation and commemoration. The current lead gives the account dated anchors—1974, 2005, 1993, 1996—that can be checked directly. The linked authority record independently contributes the date 1974-12-04. The account is most persuasive where Tadahito, Iguchi and Japanese can be independently traced.
Editorial analysis

Why this record matters

The subject matters to the people & ideas register because the source frames it as japanese baseball player. Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

Chronology provides the most reliable spine for this subject; interpretation should follow only after identities and dates are secure. The source revision retrieved here is dated Aug 18, 2026. The linked authority identifier is Q487880. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1974, 2005, 1993 and 1996.

Critical limits

Later biographies can compress uncertainty and repeat inherited reputations, so apparently settled claims may still require comparison. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Read biographical claims against dates, named institutions and the cited references. Distinguish a subject’s later reputation from evidence produced during their lifetime.
