Japanese broadcaster NHK, showed footage of grey smoke and ash billowing into the sky, while orange lava rose to the mouth of the crater.
According to reports, the volcano measuring 4,660-feet erupted molten stones and smokes to a height of up to 7,500 feet above sea level.
A volcano in southern Japan continued to erupt today, sending smoke and ash as high as 3,000 metres into the sky, the Japanese Meteorological Agency said.
Entry to the 1421-kilometre high volcano was restricted.
In Kirishima city at the foot of the volcano, pedestrians wore surgical masks or covered their noses with hand towels, while others used umbrellas to protect themselves from falling ash. No injuries or building damage have been reported.
Local authorities around the 1,421-m volcano that straddles Miyazaki and Kagoshima prefectures on the southwestern Japan main island of Kyushu remained cautious against further large-scale eruptions.
Japan, with scores of active volcanoes, sits on the so-called Pacific "Ring of Fire" where a large proportion of the world's earthquakes and volcanic eruptions are recorded.
On September 27, 2014, Japan suffered its deadliest eruption in nearly 90 years when Mount Ontake, in central Nagano prefecture, burst unexpectedly to life.
In January, a soldier from the country's Self-Defence Forces was killed and several other people injured after an eruption near a popular ski resort in northwest of Tokyo.
