To prevent flood accidents in rivers
Last updated on July 11, 2024.
Yokohama City is surrounded by 8 water systems and 56 rivers, many of which are small and medium-sized rivers with small river widths that flow through urban areas. Therefore, while the river in Yokohama has one aspect of the natural environment left in the city, it also has the characteristic that the amount of water increases rapidly during heavy rains. Summer is a season when there are many water accidents in rivers. To prevent flood accidents in rivers, please follow the following promises when playing the river.
Promises that I want to keep especially when playing in the river
Let's check the weather and water level before entering the river
The water level of the river can rise suddenly. Let's check the weather and water level in advance. The water level of the river can be confirmed at Mizu disaster prevention information, Yokohama City.
Be sure to go with an adult.
It's dangerous to play with children alone. Be sure to go with an adult.
Nature rivers have deep bottoms and slippery places.
There are places where the river looks shallow but suddenly deep, and places where it is slippery due to moss.
Wearing a life jacket to make it safer
It's safer if you wear a life jacket.

The river can change suddenly depending on the weather.
Even in a river where you can enjoy playing when it is sunny, the situation can change completely. The water may increase not only when it starts to rain where you are, but also when it rains upstream of the river.
The photo shows a comparison of rivers in the city during normal times and when the water rises.
