NFL and Japan Football History

A data-driven history of the National Football League, from a 1920 meeting in an Ohio car showroom to a $300M salary cap, and of American football in Japan, from a 1934 student league in Tokyo to a sport of about 13,000 registered players today.

Compiled November 2026 from public sources.

Data honesty: these are research notes compiled from public sources, not official NFL or JAFA data. Numbers are copied as the sources give them. Values that are unconfirmed, conflicting or seen only in a search snippet stay in the text and in the CSV note columns, and are left out of the charts. Missing years are missing, not zero.

The NFL story

The league began in 1920 as a pact between local club owners. Television made it national: the 1961 Sports Broadcasting Act let clubs pool their TV rights, and Pete Rozelle turned that money into equal revenue sharing, the AFL merger and the Super Bowl. The 1993 labor deal traded free agency for a salary cap that has grown almost ninefold since 1994. Since 2007 the league has played regular-season games abroad, a record nine of them in 2026, and the concussion crisis of the 2000s led to a settlement that has awarded over $1.7B.

Football in Japan

An American missionary, Paul Rusch, organised the first student league in Tokyo in 1934, and Japanese-American Nisei from Hawaii made up most of the early players. After the war, newspaper-sponsored bowls (the Koshien Bowl, the Rice Bowl) and US service games built the sport. It peaked in the bubble years: about 20,700 registered players in 1992, 56,000 at the Rice Bowl and NFL games every week on two networks. About 13,400 players are registered today, the X League is rebuilding after a 2026 governance crisis, and flag football is growing ahead of the LA28 Olympics.

Registered American football players in Japan
Two counting methods are mixed (JAFA history pages and the SSF survey); the gaps between points are years with no figure. FY2020 (15,756) and FY2022 (13,809) rest on one secondary summary and are not plotted. Data: Japan registered American football players over time (CSV).
