The Japan Series was the first "Kansai Showdown" between Hanshin and Orix in 59 years.
When Hanshin won the league, some people jumped into the river from the bridge in Dotonbori in Minami, Osaka, but experts who investigate the water quality of the river say, "E. coli has been detected and it is not a river that you can swim in.
When Hanshin won the league title in September, many fans gathered around the Ebi Bridge over the Dotonbori River in Minami, Osaka, to celebrate, and some jumped from the riverside promenade.
It is said that no one was injured, but when the league championship was won in 2003, more than 5000,1 people jumped into the river from the Ebi Bridge, killing one person and injuring multiple people.
The following year, since 2004, the Japan College of Analytical Chemistry in Kita-ku, Osaka, has been investigating the degree of turbidity of river water and the number of bacteria.
Water quality is improving, and last year, in November 2022, the habitat of the endangered Japanese eel was confirmed, but the detection of E. coli, which is an indicator of pollution, continues, and in the survey in August, it was about 11,8 eels per 100 milliliters of river water.
The standard for swimming pools set by the Ministry of Health, Labor and Welfare is that E. coli is not detected, and Takashi Miyamichi, director of the educational affairs department of the Japan College of Analytical Chemistry, points out that "the river is still not swimmable" and calls for caution.
Takashi Miyamichi, Director
of Academic Affairs, Japan College of Analytical Chemistry: "It's like swimming in the water that accumulates in the toilet bowl, and it can lead to health problems such as abdominal pain and diarrhea.
