Karasujima Observatory

Once an island over a century ago, "Karasujima" now lies quietly beneath this land.

Sakurajima, an active volcano and symbol of Kagoshima, continues to emit volcanic smoke even today. Once a solitary island floating in the sea for centuries, it became connected to the mainland in 1914 when a massive eruption released a torrent of lava that filled the strait between Sakurajima and Karasujima.

The hardened lava formed a vast field, and it is here that you'll find Karasujima Observatory. The rugged, blackened landscape still bears the scars of the eruption, though more than a century has passed. Now, the area is partially covered with vegetation and black pines, hinting at nature’s resilience and quiet recovery.

From the observatory, breathtaking views unfold in every direction—calm Kinko Bay, the lava plains stretching toward the sea, and the majestic cone of Sakurajima looming nearby. It’s a powerful place where visitors can truly feel the awe-inspiring force of nature and witness the lasting impact of a volcanic eruption.

Highlights

  • The closest observatory to the crater of Sakurajima’s Minami-dake peak.
  • Surrounded by lava from an eruption over 100 years ago.
  • Offers panoramic views of the cone-shaped Sakurajima and the tranquil waters of Kinko Bay.
