At night on June 3, four Deaf office workers aged between 46 and 51 caught the pleasure boat that was overturned at Mikawa Bay in Nishino-shi, Aichi Prefecture located in central Japan, and they were rescued.
One of the Deaf men requested relief using "the Telephone Relay Service" through his own smart phone. The patrol boat received the emergency notice and rescued about four hours later.
Around 5:30pm on June 3, an engine stopped the pleasure boat by some defects according to Marine Safety Station officials. They assumed that seawater might enter in the boat, which later was overturned.
