Drowning accident caused by Toshimaen's water-installed playset
The drowning accident caused by Toshimaen's water-installed playset (Toshimaen's swimming pool) is the amusement park "Toshimaen" that was in Nerima-ku, Tokyo on August 15, 2019 (the first year of Reiwa). A girl wearing a life jacket (hereinafter referred to as A) was found floating under the playset at the attraction "Fluffy Waterland" equipped with an air playset type water-installed playset in the pool of "", and then drowned. It's an accident. The accident was investigated by the Consumer Affairs Agency, and it was concluded that the accident was caused by falling into the water and then getting under the playset, making it impossible to escape due to the buoyancy of the life jacket. Based on the lessons learned from this accident, the Ministry of Economy, Trade and Industry has come up with guidelines for the safety of water play equipment.
Toshimaen, which became the scene of the accident, opened in 1926, and the pool opened in 1929, three years later. "Fluffy Waterland" has been in service since 2016. "Fluffy Waterland" was installed in a swimming pool with 8 lanes, 50 meters long, 20 meters wide, 1.2 to 1.9 meters deep, and A's height can reach the bottom of the water. There were some places that weren't there. In "Fluffy Waterland", more than 10 water-installed playsets called air playset type were installed. This is technically called an air film structure playset, and it is a playset that floats on the surface of the water by injecting air. The advantage is that you can do it. However, a net to prevent entry under the playset was not installed. The planning and design of "Fluffy Waterland" was originally done by Toshimaen, and the playset was procured from a manufacturer in the People's Republic of China. The playset on which A fell was large enough to allow 15 people, including adults and children, to play at once. According to a man who says that Tokyo Sports uses "fluffy waterland" with children every year, the playset is more than 30 centimeters thick and the surface is smooth, so the child is alone. It is impossible to climb the playset from the water, and even an adult will not be able to escape if he gets under the playset while wearing the life jacket described later.
In "Fluffy Waterland", the user had to be 1.1 meters or more in height and wear a rented life jacket to prevent drowning and entry under the playset. The life jacket rented out at "Fluffy Waterland" was a solid structure that gained buoyancy using Styrofoam, and was shaped like a waistcoat. It was a form in which both arms were passed through the waistcoat and fastened in front to make adjustments. In addition, the users of "Fluffy Waterland" were verbally asked if they could swim alone. Witnesses to the accident testified that more users wore buoys on their arms. In "Fluffy Waterland", there were many people who fell into the water from the playset, and in addition, there were two people who dropped goggles into the water every hour.
A was a girl in the third grade of elementary school who lived in Asaka City, Saitama Prefecture at that time, and she was eight years old. On the day of the accident, A is her father (hereinafter referred to as B).
