His grandson, Wada Kakuemon Yoriharu, later known as Taiji Kakuemon Yoriharu, invented the whaling net technique called amitori-shiki (網取り式).
Instead of trying to harpoon whales in open water, now twenty or more boats would encircle a whale and make a racket, driving it towards the shallows into nets wielded by a second group of six boats.
Supporters of the Japanese whaling tradition claim that the experience is both humble and emotional, and all parts of a whale are used, unlike westerners of the past who hunted only for whale oil.
In addition, Japan has strictly controlled catch quotas, and whalers have never hunted juveniles or cow/calf pairs due to their respect for whales.
Antarctic minke whale have experienced an apparent decline in population, though the International Union for Conservation of Nature (IUCN) indicates that it lacks sufficient data to confer a "threatened" designation on the species of minke whale.
