I found this news on Twitter. I saw someone shares Japan to withdraw from IWC to resume commercial whaling: sources as a post of Stop Sea Shepherd Violence! group on Facebook and I shared the same link on 20 Dec. 2018.
IWC is settled for sustainable whaling. It’s the aim of International Convention for the Regulation of Whaling.
Having decided to conclude a convention to provide for the proper conservation of whale stocks and thus make possible the orderly development of the whaling industry;
But they violate our rights of whaling itself against the contract. Anti-whaling countries including Australia and activists including Green Peace insult our scientific whaling for not scientific in spite of the fact that we show various scientific papers to IWC’s Scientific Committee. Anti-whaling foreigners don’t try to know the aim of IWC but they lie about the laws including the convention, about scientific facts including the estimates of whale populations. We cannot help that situation. So we, Japan need to withdraw from it.
