The article discusses a double header played on October 19, 1988 between the Kintetsu Buffaloes and the Lotte Orions. The Buffaloes needed to sweep the last place Orions to pass the Lions (who had already completed their schedule) and clinch the Pacific League pennant. They won the first game 4-3 but were unable to hold a similar 4-3 lead in the second game when Hideaki Takazawa homered in the bottom of the eighth to tie the game up. The game ended as a tie after 10 innings (which was the limit at the time) and the Lions won the PL pennant (and went on to beat the Dragons in the Nippon Series). This particular doubleheader is known in Japan simply as "10.19"
BBM's 2016 "Historic Collection" set celebrating events at old ballparks (The Ballpark Stories) has three cards that deal with this day. I'm fairly certain that the photos on the cards are from the games. There's a card of Buffaloes pitcher Hideyuki Awano, who got the save in the first game and I think gave up the home run to Takazawa in the second game:
