Masuda's last known whereabouts on September 3, 2006, at 7:55 AM, was the northbound 405 Freeway at Montana Street, where he accessed a Call Box, requesting assistance because he had run out of gas. On September 3, 2006, at 8:25 AM, Masuda's rented vehicle was found abandoned (out of gas) at the location. As a California Highway Patrol officer was impounding the vehicle, he found photo equipment still in the vehicle. There was no evidence of foul play, but Masuda is listed as missing under "unknown circumstances." The vehicle has since been released back to the rental agency.

Masuda's physical and mental health is described as good. He has no prior history of being missing. Family and co-workers describe him as being very responsible and his disappearance as being out of character. He has lived in San Diego in the past and is familiar with the area. He also speaks both English and Japanese.
