THE ASAHI SHIMBUN

MINAMI-AWAJI, Hyogo Prefecture--It would seem that even the humble sea firefly likes to be noticed, especially when large groups form.

Summer is the perfect time to witness the marine blue glow that emerges when sea fireflies congregate.

One of the best spots to observe this treasure of nature is in Minami-Awaji's Amahigashi district.

The Awaji Island Tourism Association and a local hotel organize tours to the beach for visitors to the island.

The sea firefly, an arthropod about 3 millimeters long, reacts to physical stimulus, such as poking or touching, when a light is shone.

To catch fireflies, organizers place glass bottles with microorganisms that fireflies feed upon. Once collected, the fireflies are placed on black steel trays or scattered on the shore bank.

The Hotel New Awaji Plaza Awajishima runs an observation event through August.

Only the first 28 applicants each day will be accepted. There is no charge.

A reservation is required. For details, contact the hotel at 0799-55-2500.

The Awaji Island Tourism Association will also organize a free firefly observation event on Aug. 24, 26 and 31.

For reservations, contact the association’s Sumoto tourism office at 0799-22-0742 or Minami-Awaji office at 0799-52-2336.
