Small tsunami waves on Friday reached Japan following a deadly earthquake in Peru, resulting in the closure of beaches along Japan's Pacific coast.
Japan's Meteorological Agency said waves of up to 20 centimetres reached parts of the coast on Friday morning, hours after a tsunami advisory was issued covering Hokkaido in the north to the southern island of Okinawa.
Minor sea level changes were expected today, but not big enough to cause any damage, the agency said. Still, surfers and swimmers were advised to stay away from the sea.
TV footage showed lifeguards telling holiday-makers that beaches were closed.
Japan issues tsunami warnings even when only tiny waves are expected, and the country's most heavily populated coastlines are fitted with loudspeakers to order evacuations.
The quake in Peru's southern desert on Wednesday killed at least 510 people and injured more than 1,500.
