Peter-Hans Kolvenbach (get his name right) was the 29th Superior General of the Society of Jesus. He wasn't "hunted down and killed" shortly after 2011; he died of natural causes in 2016 at the age of 87. And he had nothing to do with the Fukushima disaster.
As per Google Books' blurb on Leo Lyon Zagami :
Praised as a top expert on the Vatican and Secret Societies by important figures of todays war against Satanism and the New World Order, such as Alex Jones, Zagami is now regarded in the US and around the world, as a househould name in the fight against the Occult elite... Zagami...explains for the first time in detail, how the network of Secret Societies, that include Freemasonry, and various Illuminati groups and orders, born out of the Western Initiatic System, were gradually corrupt by evil forces and black magic, that facilitated in turn, the rise of modern Satanism, and atheism, and the decline of our Society. Zagami shows in depth the secret traditions, and techniques, used by the so-called "Iluminati," to achieve this, which range from telepathy to sexual magick, to help us understand the real crisis in Freemasonry and the Illuminati, that pushed the birth of a One World Communistic Government, and the implementation of a One World Religion, using the unusual alliance between Marxism and Islam, both linked to Satanism.

According to his bio at his website leozagami.com, he published books in Japan between 2009 and 2013. No clue as to his involvement with the Fukushima tsunami.
Israeli Prime Minister Benjamin Netanyahu is "at large" on our television screens every night due to Israeli actions in Gaza. Again, no hint of any involvement with the Fukushima tsunami.
