WCH Tokyo 25 heat countermeasures
With extreme heat expected during the World Athletics Championships Tokyo 25, we are working closely with the Tokyo Metropolitan Government and relevant agencies to implement comprehensive heat countermeasures to ensure the safety of athletes, spectators, officials, volunteers, and staff.
This page provides information on the heat countermeasures in place for WCH Tokyo 25. The content will be updated regularly as additional details are confirmed. We kindly encourage all participants and spectators to review this information and take appropriate precautions against heat when attending the championships.
Before you leave home
Please remember to stay hydrated, replenish salts regularly, wear light and breathable clothing, and make use of cooling items.
We also encourage you to consult the Tokyo Metropolitan Government’s Heatstroke Prevention Portal for further guidance and to remain alert to the risks of heatstroke.
Before coming to the venue, please check the Tokyo Heat Map for WBGT (Wet Bulb Globe Temperature) index estimates on the day before and the day of your visit.
Before Entering the Japan National Stadium
Tokyo Heat Countermeasures Guide Map
- Please make use of the PDF guide provided by the Tokyo Metropolitan Government with information on free drinks, rest areas, and more.
Cooling Spots
- Six cooling spots will be available for spectators around the stadium.
- Benches and cooling fans will be provided.
- Drinking water will be available. Please bring your own bottle.

Inside the Japan National Stadium
Spectators may bring in plastic bottles or personal water bottles. Please remember to stay hydrated throughout your ticketed event.
Heat information and reminders (e.g. hydration breaks) will be shared via the stadium’s large screens, digital signage, and public announcements.
Existing mist showers and airflow fans inside the stadium will be used to help lower the perceived temperature.
If you feel unwell, please approach a volunteer first responder (patrolling the spectator areas) or visit one of the spectator medical rooms located on each floor.
Roadside Spectator Rest Areas
Thirteen rest areas will be set up along the marathon route where spectators can take temporary shelter from the heat.
Due to the marathon competition start time being changed to 7:30 a.m., the rest areas will also open from 7:30 a.m. in accordance with the new start time.
*Please note that the rest areas at the Chiyoda City Office Manseibashi Branch and the Chuo City Tourist Information Center will open at 9:00 a.m.
(as of 11 September)

The WCH Tokyo 25 Sustainability Plan
The WCH Tokyo 25 Sustainability Plan outlines our approach to delivering an environmentally and socially responsible World Championships. Developed in collaboration with event sponsors and the Tokyo Metropolitan Government, this plan reflects our shared ambition to leave a meaningful legacy for future international sporting events.
Anchored by the six sustainability pillars that frame the World Athletics Sustainability Strategy - Leadership, Sustainable Production and Consumption, Climate Change and Carbon, Local Environment and Air Quality, Global Equality, and Diversity, Accessibility and Well-being - the WCH Tokyo 25 Sustainability Plan builds on the vision set out in our Basic Plan. Our goal: to establish a new global benchmark for sustainable sports events, known as the Tokyo Model.
In addition to minimising our environmental footprint, WCH Tokyo 25 is committed to championing diversity, equity, and transparency throughout its planning and operations.
A comprehensive sustainability report will be published after the Championships, providing insights into the impact of our efforts and underscoring our commitment to lasting positive change in global event hosting.
As part of this mission, we aim to achieve Platinum level certification against ‘Athletics for a Better World Standard’, an evaluation framework designed by World Athletics that measures an event’s alignment with sustainable delivery practices and the six guiding pillars.
Key Focus Areas
Our plan promotes sustainability across two core areas and five subcategories:
1. Environmental Initiatives
- Climate Change, Energy and Heat Countermeasures
- Resource Circulation, Sustainable Procurement and Waste Reduction
- Environmental Enhancement
2. Social Initiatives
- Transparent and Inclusive Operations
- Diversity, Well-being and Sports Participation
The following are some examples of the initiatives being implemented across our environmental initiatives. Please note that this is not an exhaustive list.
Climate Change, Energy and Heat Countermeasures
Harnessing Next-Generation Solar Technology
Garden lights featuring cutting-edge solar cells are being installed around the Japan National Stadium. These lights will remain in place after the Championships, serving the local community and symbolising a lasting contribution to urban sustainability.
Expanding the Use of Biofuels
Temporary broadcast generators at the stadium will be powered by biofuels, reducing dependency on fossil fuels. A portion of the official vehicle fleet will also run on biofuel, further lowering the event’s carbon footprint.
Sustainable Aviation Fuel (SAF) from Recycled Cooking Oil
Flights transporting athletes will use Sustainable Aviation Fuel derived from waste cooking oil collected in Tokyo — a pioneering initiative that supports the global push toward greener air travel.
Reducing CO₂ Emissions Through Renewable Energy and Offsetting
All electricity purchased for the Championships will be certified renewable, sourced via green power certificates. In addition, carbon offsetting projects, supported by official partners, will help neutralise unavoidable emissions generated during the event.
Resource Circulation, Sustainable Procurement and Waste Reduction
Sustainable Sourcing and Smarter Waste Management
A dedicated sustainable procurement policy is guiding all sourcing decisions. Wherever possible, items are being rented or leased to reduce waste. Environmentally responsible products are prioritised when purchases are determined to be necessary. After the Championships, sporting equipment will be reused or appropriately redistributed in line with asset disposal procedures. Spectators will be encouraged to bring reusable water bottles, and returnable bottle schemes are being explored in select areas. WCH Tokyo 25 is also working to minimise single-use plastics in food and beverage packaging.
Tackling Food Waste with Smarter Planning
To cut down on waste, volunteers will receive prepaid cards instead of catered meals, giving them more flexibility while reducing unnecessary food preparation. Meals for staff and officials will be portioned carefully, and frozen ingredients will be used strategically. Unused food will be recycled or repurposed wherever possible.
Environmental Enhancements
Community Engagement and Local Action
A “plogging” initiative (jogging while picking up litter) will be held around the Japan National Stadium in partnership with sponsors, encouraging community participation in environmental cleanup efforts.
Real-Time Air Quality Monitoring
Working alongside World Athletics, we will install air quality monitoring systems at the stadium. This real-time data will be available to athletes and staff, contributing to a safer and healthier competition environment.
WCH Tokyo 25 will serve as a model for how major international sporting events can be delivered responsibly and transparently. Through collaboration with partners, innovative use of technology, and a focus on long-term impact, the Championships aim to set a new benchmark for sustainability in global sports.
As preparations continue, spectators are encouraged to support and participate in this new chapter of event delivery!
The Used Cooking Oil Collection Campaign
Used cooking oil from households and restaurants is expected to serve as a key raw material for the production of Sustainable Aviation Fuel (SAF).
The Tokyo Metropolitan Government, in collaboration with local municipalities, will set up collection points to encourage households to recycle their used cooking oil. The collected oil will be refined into SAF at Japan's first large-scale SAF production facility in Sakai City, Osaka, and then transported to airports across Japan, including Tokyo International Airport (Haneda), where it will be used as aviation fuel.
Household cooking oil coollection at the Japan National Stadium
From 13 to 21 September, WCH Tokyo 25 will collect household cooking oil at three booths located around the Japan National Stadium below:
1) Revo International Booth (open 10:00–20:00)
2) WCH Tokyo 25 booth (open 10:00–20:00)
3) Tokyo Metropolitan Government Environment Bureau Booth (open 12:00–18:00* – times may vary depending on the competition schedule)
The locations of booths 1 and 2 can be found here.
Period of Campaign: From Friday 2 May 2025 to Friday 31 October 2025
