after donating the inheritance from her late husband and father to the Church, as a result Tetsuya had to quit his college study, his brother commited suicide after falling ill. Founded by Korean Reverend Sun Myung Moon, the group is now HQ in the US. This sounds like the doing of the FLG cult, soliciting donation from blind followers, also HQ in the US now. Both pushing their own twisted political agenda. If I'm not mistaken, Unification Church is also banned in China. He targeted Abe due to his connection to the religious group, whether this is his true motive or not.
I'm sure the Japanese politician are going to waste no time in pushing through the constitution revision, in particular to the article 9, seizing upon Abe's death. Instead of wasting time on regulating predatory occult activities, improving economy and job opportunities, they're more obsessed with the right to wage war against Japan's neighbor.
Their arrogance can be reflected in this 2015 House debate, when female representative Kiyomi Tsujimoto warned Abe that Japan society is not as safe as he think, and Abe had to be more alert to terrorism attack, particularly against a PM such as himself. Abe mocked and ridiculed her portrayal of Japan society as unsafe, and received applause from the male representatives.
Another thing to observe in this video is the male chauvinism in Japan politic. Not only Kiyomi chose to dress up like a man, she was frequently interrupted and mocked by the male representatives in her speech.
