As it turned out, in Japan, the eruption of a volcano located next to the stadium is absolutely no reason to cancel a football match.
The other day, the Sakurajima volcano, which is located on the island of Kyushu, woke up right before the start of the home match of the local Kagoshima United football team, which plays in the third Japanese division, but this did not prompt the organizers of the meeting to cancel it. Equanimity was maintained by the participants of the match, as well as by the fans, who, as if nothing had happened, remained in the stands.
Interestingly, the Sakurajima volcano is considered the most active in Japan.
