He had been missing since Sunday afternoon.
The surfboard used by Matsumoto, 31, was found and turned over to DPS yesterday.
Matsumoto’s parents arrived on the early Tuesday.
“We’re going to give ourselves one more day,” said DPS Commissioner Santiago Tudela in a chance interview the command post set up at Sugar Dock.
Emergency Management Office deputy director Mark Pangelinan said Matsumoto’s parents are asking the Office of the Governor for an extension of the search.
The standard policy is 72 hours for a search mission, Pangelinan said.
DPS Boating Safety Section officer-in-charge Sgt. Bernard Santos said Matsumoto was a Hyatt Regency employee and has been on island for about nine years.
His wife also works at the Hyatt, Santos said.
Asked for comment, a Hyatt staff member said the right person to talk to was off-island, while another hotel official was not at their office yesterday.
Santos said Duty Free Shoppers’ Jeff Taylor and Boyet Centeno brought the surfboard to the police yesterday.
It was Centeno who found it at about 8:30 a.m., Tuesday, on the shoreline across from the $3 Store on Beach Road in Chalan Laulau.
Centeno was fishing at the time when he saw the surfboard on the beach.
After taking the surfboard home, Centeno learned about the missing surfer after reading the newspaper.
Centeno then told Taylor about surfboard.
PO2 Elias Saralu learned that the surfboard was rented from a surfshop in Garapan.
Police confirmed that it was the surfboard rented by Matsumoto.
DPS acting spokesman PO2 Jason Tarkong said the surf at Sugar Dock was still hazardous.
But despite the advisories from the authorities, some people were still surfing in the area, police said.
Four certified divers from the Coastal Resource Management Office have joined the search and are assisting eight divers from the DPS Boating Safety and Dive Rescue Team, Santos said.
The divers were aided by two units of jetski as well as DPS and CRMO boats.
A U.S. Coast Guard cutter is still participating in the search but the Coast Guard helicopter is no longer involved in the operation, Tarkong said.
EMO and DPS Fire Search and Rescue Unit, for their part, are conducting surface searches, Tarkong said.
