Small employers in Tokyo have a five-day window, October 19 to 23, 2026, to enter the fourth round of a grant program that pays for heatstroke prevention at workplaces. Entry is not first come, first served. The program runs a lottery to pick which businesses pass the entry stage.
How the entry round works
The listing for the heat-conscious workplace grant, titled as the fourth round of the 2026 fiscal year's program, says applicants are chosen by draw. It still asks businesses to apply during the window to avoid congestion on the access system, and to read the program's application guidelines before entering. The program is sized at 1,000 businesses.
The stated purpose is to pay a grant to small Tokyo businesses that have workplaces where heatstroke is a risk and that take preventive measures, so as to encourage heat-conscious working conditions. The foundation administering the program pays under its own grant rules, a payment procedure and the guidelines.
Who can enter
Eligible applicants are small businesses in Tokyo as defined by the Small and Medium-sized Enterprise Basic Act. The listing sets the limit at 20 or fewer regular employees, or five or fewer in commerce and services. On the date of the grant application, the business must also employ someone who has been covered by employment insurance for at least six months.
Earlier rounds
The fourth round follows three earlier entry windows: April 27 to May 13, June 22 to 26, and August 24 to 28, all in 2026. Whether unsuccessful entrants from earlier rounds may enter again is not addressed in the listing.
The listing does not give a grant amount per business or say which prevention measures qualify. It tells applicants to check the foundation's application guidelines before entering. Enquiries go to the heat-countermeasure support team in the foundation's employment environment division.
