Cleanup workers are sweeping up mounds of ash in a southwestern Japanese city after a volcano erupted on Sunday.

The volcano sent a plume of smoke into the air over the weekend.

So far, it has erupted 500 times this year and it spread ash over a wide area.

The city was shrouded in an ash cloud causing poor visibility at times.

Residents used masks and umbrellas to protect themselves.
