01 / Firefly squid viewing
Boats built to show off glowing squid,back in 1910.

In 1909 the town of Namerikawa promoted the firefly squid in a booklet as one of its "Two Great Wonders" (二大奇観), alongside the mirage, and the next year it built two viewing boats. Today's sea tour dates from 1987: before dawn in spring, boats leave Namerikawa Fishing Port so visitors can watch fishermen haul up the set nets. The oldest known record of the squid, a "koika" (小烏賊) entry from 1858, is also in a Namerikawa document.
