Hotaruika (Firefly Squid) Night Fishing
From March to May, millions of bioluminescent firefly squid (hotaruika) come to shore in Toyama Bay to spawn, creating a ghostly blue glow visible in dark waters offshore. Viewing boats depart at 3 a.m. from Namerikawa fishing port, and observers watch the glowing blue creatures emerge in waves โ one of Japan's most extraordinary natural phenomena.
