It is quite surprising to those of us who weren’t in Japan in the 1970s how different the ballpark experience is now compared to 40 years ago. Combing through newspaper clippings from 1973 and 1974 while looking to document changes within the game, I was struck by what a dangerous place Japanese ballparks were.

I had witnessed some pretty obnoxious behavior in the ’80s and early ’90s when people cheering for the wrong team in the wrong part of the ballpark were punched in the bleachers, but that is pretty rare in my experience here and that also happened sometimes at games I’d attended at Candlestick Park in the 1970s.

The first to catch my eye was a report on May 3, 1974, in which Hall of Fame outfielder Isao Harimoto attacked an opposing player before the start of a game, kicking a member of the Lotte Orions with his spikes, apparently because the guy had been heckling him for a couple of games.

Five days later, Nippon Ham Fighters infielder Toshizo Sakamoto was in the field at his home park, Tokyo’s Korakuen Stadium, while Taiheiyo Club Lions manager Kazuhisa Inao had a heated exchange over a called third strike, when a sake bottle came hurling out of the stands. It didn’t hit Sakamoto, but the Fighters shortstop walked toward the stands and said, “Hey, don’t you think that’s dangerous?” Another fan answered Sakamoto’s rhetorical question with an empty beer bottle, that struck Sakamoto in the head.

On May 30, empty beer bottles were thrown at reporters in the press seats at Koshien Stadium,  the Hanshin Tigers’ home park, while several stories in the spring detailed incidents involving Orions manager Masaichi Kaneda’s threatening abusive fans with a bat — after he’d been warned in the offseason to mind his Ps and Qs after calling Pacific League owners cheapskates. The owners were cheapskates, of course, as documented by the union’s demand over the previous offseason that the teams pay for the players’ bats and gloves.

At some point, commissioner Nobumoto Ohama took notice and on May 31 instructed the teams to avoid arguing too much as it would “enflame the passions of the fans” and lead to bad behavior.

Until I came across these articles, I was under the impression the fan riots during the 1975 season at two different games between the Hiroshima Carp and Chunichi Dragons were rare and isolated instances.
