The Taiji Dolphin Drive Hunt: Annual Slaughter and Captivity Trade

Controversial Japanese Practice

Each year (Sept–Mar), in Taiji, Wakayama Prefecture, fishermen conduct drive hunts (oikomi):

Process

1. Boats herd dolphin pods into a narrow cove using acoustic barriers (banging poles).
2. Nets seal the cove.
3. Trainers select "show-quality" individuals for sale to aquariums/marine parks (globally).
4. Remaining dolphins slaughtered for meat (despite high mercury).
5. Carcasses processed locally.

Scale

Quota ~1,000–2,000 cetaceans/year (bottlenose, striped, Risso's, pilot whales).

Criticism

• Cruelty: Prolonged stress, inhumane killing (spinal lance).
• Health: Dolphin meat exceeds mercury limits; mislabeled as whale.
• Conservation: Non-selective; impacts population viability.
• Legal: Challenges under IWC, CITES, Japanese law.

Defense

Taiji claims "traditional food culture"; government permits quotas. Documentaries (The Cove, 2009) sparked global outcry. JAZA (Japanese aquarium association) banned members from buying Taiji dolphins (2015), but exports continue to China, Middle East, Russia.
