Where is Nichiren Lotus Sutra Buddhism faithfully taught and practiced?

Go to the Soka Gakkai Institute of Oriental Philosphy page (http://www.iop.or.jp/index.html) and search for any articles on Nichiren's Lotus Sutra Buddhism. Then search for articles on other sects of Buddhism, Islam, Christianity, and Confucianism. One can come to no other conclusion that Nichiren and Nichiren Lotus Sutra Buddhism is now marginalized in the Soka Gakkai. Truthfully, only here is Nichiren Lotus Sutra Buddhism faithfully taught and practiced, exactly as Nichiren in his authenticated writings.
