Which 1986 film's TV screening set a Twitter record of 143,199 tweets per second in Japan?

The 1986 film was Castle in the Sky, whose Japanese television screening produced a Twitter record of 143,199 tweets per second. The record was reported on August 3, 2013, as viewers reacted to the broadcast.

Castle in the Sky is a Japanese animated fantasy adventure directed by Hayao Miyazaki and produced by Studio Ghibli. Its Japanese title is Tenkū no Shiro Rapyuta, and it was released in 1986 as the studio’s first official production. The film follows Sheeta and Pazu as they search for the legendary floating city of Laputa while being pursued by government agents and pirates.

The Twitter statistic belongs to a wider history of television-driven spikes in online activity. Before Castle in the Sky’s 143,199-tweet rate, another Japanese screening of the same film had reportedly produced 33,388 tweets per second. The record is often confused with Twitter spikes surrounding sports finals, New Year celebrations, or other Studio Ghibli movies, but the specific 143,199 figure is tied to Castle in the Sky.
