An earthquake with an estimated magnitude of 5.1 rattled parts of Tokyo and its vicinity on Saturday, about two hours before U.S. President Donald Trump's arrival on a four-day visit as a state guest, but no tsunami warning was issued, the weather agency said.

The epicenter of the quake, which occurred at 3:20 p.m. at a depth of 38 kilometers, was southern Chiba Prefecture, the agency said. It is right around the area where Trump is scheduled to play golf with Prime Minister Shinzo Abe on Sunday.

The quake at the most registered a lower 5 on the Japanese seismic intensity scale of 7 in Chonan, a town about 60 kilometers southeast of Tokyo and just next to the city of Mobara where the two leaders' golf venue is located.

"There were two shocks and they shook vertically," Harue Yasuda, 76, a shopkeeper in the town said. "I told about five or six customers at the shop at the time to go outside immediately to evacuate. A couple of light bottles fell from a shelf."

The Japan Meteorological Agency warned that a quake with about the same intensity could hit the areas over the next week or so.

It registered 4 on the intensity scale in some other parts of the prefecture, as well as Chuo Ward in central Tokyo.

The government set up an emergency unit at the prime minister's office to gather information. But so far there have been no reports of major damage.

An 84-year-old woman was injured after she fell at her home in the city of Chiba, according to a local fire department.

No flights to or from Narita international airport in the prefecture were affected by the quake, according to the transport ministry's local office.

Some bullet train services were temporarily suspended and trains on local lines were partially delayed, according to operators.
