The developer of a “starting light” device hopes that the Tokyo 2025 Deaflympics, which began on Saturday, will raise awareness about the deaf community.

The device is used alongside the starting pistol for track events at the quadrennial sports festival for people with hearing difficulties.

“I hope people become more aware of the difficulties that those who are hard of hearing go through,” said Masahisa Takemi, a 50-year-old teacher at the Central School for the Deaf, run by the Tokyo Metropolitan Government, who was involved in the development of the device.
