Deletion of Bungakuza

Comment: I added a book reference which describes this as ''"one of Japan's most illustrious shingeki troupes"''. Other books showing in a Google Books search describe it as one of 3 ''"leading Shingeki companies"'', as one of 2 ''"two major shingeki companies"'', etc. See in particular the summary on https://books.google.co.uk/books?id=maGU4ziPQJQC&newbks=1&newbks_redir=0&lpg=PA226&pg=PA226#v=onepage this page about their work. Overall, sufficient critical attention to demonstrate |notability
