Postwar Recovery and the Dawn of Radio Broadcasting
Japanese professional baseball radio broadcasting began around the same time as the professional baseball league's founding in 1936, but its true golden age arrived after the war. Immediately following the end of World War II in 1945, GHQ encouraged sports revival as part of its democratization policy, and NHK resumed professional baseball broadcasts in 1946. At the time, radio was the only electronic medium available to ordinary households, and baseball broadcasts were positioned at the center of national entertainment. During the 1947 Japan Series broadcast, scenes of hundreds gathering around street-side radios were witnessed across the country. Radio broadcasting was the only means of following games for fans in rural areas who could not visit stadiums, becoming the driving force that elevated professional baseball into a nationwide sport. As commercial broadcasting stations opened one after another alongside NHK, each competed to acquire baseball broadcasting rights, and broadcast times came to dominate evening prime time.

The Era of Legendary Announcers
What defined the appeal of radio baseball broadcasting was the presence of distinctive play-by-play announcers. NHK's Masayori Shimura, called the 'God of Broadcasting,' built the foundation of postwar radio broadcasting with his accurate and vivid commentary. Shimura's play-by-play possessed such descriptive power that listeners could visualize the stadium scene with their eyes closed, becoming a model for subsequent announcers. In commercial broadcasting, Nippon Broadcasting's Hiroshi Fukazawa gained tremendous popularity with Giants game broadcasts, and 'Giants games on radio' became a brand in itself. Play-by-play announcers were not mere information conveyors but entertainers who amplified the excitement of games. Their passionate calls during memorable moments became essential elements in forming game memories alongside the next day's newspaper headlines. Famous phrases from radio commentary are still passed down today, testifying to the richness of audio expression in Japanese baseball culture.
The Television Era and Radio's Transformation
The start of television broadcasting in 1953 brought a major turning point for radio baseball coverage. Faced with television's overwhelming information capacity through visual imagery, radio yielded its leading role. By the 1960s, television penetration rates rose rapidly, and Giants game telecasts became national programming exceeding 30% viewership. However, radio broadcasting far from disappeared, instead achieving its own unique evolution. Detailed commentary that television could not fully convey, interactive communication with listeners, and the new listening style of 'while-listening' redefined radio broadcasting's raison d'etre. For taxi drivers and night-shift workers, radio broadcasts remained an indispensable companion. Additionally, while television coverage was heavily biased toward Giants games, radio maintained its value as a precious medium for following Pacific League games. Television and radio existed not in competition but in complementary relationship, each supporting baseball fans in different listening contexts.

Radio Broadcasting in the Digital Age and the Future of Audio Media
Since the 2010s, the emergence of radiko has made radio broadcasts accessible nationwide via the internet. Local station broadcasts that were previously region-limited now reach fans across the country, and radio broadcasting is entering a new golden age. Furthermore, the spread of podcasts and audio social media has given birth to a new genre of baseball talk shows beyond game broadcasts. In-depth analysis by former players and commentators provides an intensive baseball experience impossible within television's brief commentary segments. Meanwhile, the rise of video streaming services has led to a declining trend in radio listener numbers. However, radio's convenience of being listenable during commutes or work represents an inherent value that visual media cannot replace. The approximately 90-year history of radio baseball broadcasting proves that the audio baseball experience remains immortal regardless of changes in the media environment.
