Around 30 earthquakes, one of them magnitude 6.2, rocked a volcanic island south of Tokyo Wednesday and another significant quake hit the northeast of the country, the national meteorological agency said.
The biggest tremor shook Miyake Island, which lies 175 kilometres (110 miles) south of Tokyo, at around 5:57 pm (0857 GMT). Its depth was 20 kilometres and there was no risk of a tsunami, the Japan Meteorological Agency said.
"There may be slight changes in the level of sea along Japan's coast but there is no fear of damage resulting from this quake," it added.
