Hot spring facilities have a responsibility to display caution signs in areas that are slippery and manage the facility so that guests can use it safely. If your fall was caused by an issue with the management of the facility, you can claim medical expenses or a refund of the cost of using the facility. However, it will be difficult to judge whether the facility management was sufficient or not, as opinions may vary. If you are unable to reach a solution by talking it out, we recommend that you get the assistance of a legal specialist with regard to the scope of damages or amount of compensation you seek.
