The ships, which are set to be joined by vessels from the southern port of Shimonoseki, will spend much of the summer hunting for minke and Baird's beaked whales.
Japan is an IWC member and therefore was banned from commercial hunts of large whales. On Monday, the country officially left the International Whaling Commission (IWC), which regulates whaling globally.
Japan has long maintained that many species of whale are not endangered and the International Whaling Commission moratorium, in place since 1986, was not justified. The mummy manufacturing facility ship Nisshin-maru and two purple meat up boats that traditional to head to the Antarctic will tear so some distance as Japan's 200 nautical mile uncommon financial zone to make a selection minke, Bryde's and sei whales. Japan's exit from the IWC doesn't threaten the organisation's activities and every effort should be made to continue this important research. The meat of the killed whales was finally nevertheless used for consumption.
The country has long said that only a few species of whales are endangered and industry supporters, as well as Prime Minister Shinzo Abe, have campaigned to resume whaling, Reuters reported. Shimonoseki thrived with factories processing whale meat and restaurants serving dishes offering it.
"The resumption of commercial whaling has been an ardent wish for whalers across the country", Shigeto Hase, the head of Japan's fisheries agency, said at the departure ceremony in Kushiro adding the resumption of commercial whaling would ensure "the culture and way of life will be passed on to the next generation".
At its peak in the 1950s, 2,000 whales were landed at the port amid growing demand for their meat as a key source of protein in the desperately poor years following World War II. Anti-whaling nations, led by Australia, the European Union and the United States, defeated Japan's "Way Forward" proposal in a 41-to-27 vote. It drastically nick support its pick in most modern years after global protests escalated and whale meat consumption slumped at dwelling. "If you force others not to eat what you do not eat yourself, that's cultural imperialism", Hideki Moronuki, senior fisheries negotiator at Japan's Fisheries Agency, told Al Jazeera.
Today, about 4,000-5,000 tons are supplied in Japan annually, or 30-40 grams (1-1.4 ounces) of whale meat per person a year, Fisheries Agency officials say.
The IWC's moratorium on commercial whaling has broadly been a success - whale populations have increased where whaling was the primary threat.
Environmentalists worldwide urged leaders at the summit in the western city of Osaka not to ignore what they called a cruel assault on whales.
There is a fear from some conservation groups that other pro-whaling countries like Russian Federation might follow Japan's example and start commercial whaling again.
"What we are seeing is the beginning of the end of Japanese whaling", said Patrick Ramage, director of the International Fund for Animal Welfare.
Iceland caught only 17 whales, while Norway hunted 432 for the 2017-2018 season, way below their catch quota of 378 and 1,278 respectively, according to the IWC.
Also known as Eden's whale, they number just under 170, according to a 20-year old stocktake, Cooke said.
