Policies and Regulations

The OLC Group has been making consistent efforts to eliminate the wasting of resources by purifying wastewater and promoting the use of reclaimed water on a voluntary basis since opening its first Theme Park to the public.
By introducing the latest cutting-edge systems, we take environmentally friendly measures at all stages of the life cycles of attractions and facilities, from design to introduction, repair and replacement.

The water used at Theme Parks is collected and purified at a water treatment plant owned by the OLC Group. Today, around 30% of the water we use (882 m3) is recycled at the OLC Group's water treatment plant and reused for toilet flushing at Tokyo Disneyland and Tokyo DisneySea.

Recycling of Water in Water Areas

Water circulates efficiently throughout Tokyo DisneySea
Water circulates efficiently throughout Tokyo DisneySea

We have placed filtration devices in the areas and attractions containing water at Theme Parks. The devices enable us to maintain water quality by conducting thorough checks and effectively circulating all water.
 For example, the water contained in the vast water areas within Tokyo DisneySea is processed through a large-scale cycle filtration/purification system. Thanks to this system, we can efficiently maintain a consistent level of water by replenishing stocks on sunny days to make up for water lost to evaporation and make adjustments to deal with overflows on rainy days. Clean water used for fountains pours into the bodies of water located throughout Tokyo DisneySea, allowing us to use water effectively without wasting any of it.

Measures Taken at Hotels

Tokyo Disney Resort's

At Disney Ambassador Hotel, Tokyo DisneySea Hotel MiraCosta and Tokyo Disneyland Hotel, we try to save laundry water by asking Guests to kindly leave towels in the bathtub only if they would like them to be changed.
