"Air India flight AI-306 of March 11 to Tokyo stands cancelled in view of the situation due to the earthquake and floods in Japan. The flight AI-314 to Osaka is expected to operate as per schedule," said a statement by the airline.

According to the statement, Air India operates seven flights to Japan every week -- four flights to Tokyo's main international airport at Narita and three to Osaka.

Meanwhile, the Indian government has offered its sympathies and assistance to the Japanese government in the aftermath of a magnitude-8.9 earthquake that hit the north-eastern parts of the country.

The quake generated a tsunami as high as 10 metres that hit the coast of Miyagi prefecture, killing at least 60 people.

Several Pacific coastal cities in different countries are still on tsunami alert.
