You could go to Wikipedia, Google or any other search engines to find out information about this person, under Kabuki, Kabuki Actor, or you could use his name. There has to be information listed somewhere, but you need to do the work yourself. His kabuki career is outlined here: http://www.kabuki21.com/hashizo2.php A good filmography (Japanese) with photos can be found here: http://nihon-eiga.fan-site.net/hasizo-no-kobeya.htm His wife, Mariko Niwa Okawa, wrote a book, but it's out of print. You may be able to find it on the web. "ふたりひとつ わたしの橋蔵親分". She also compiled a pictorial filmography of his work "大川橋蔵", available in hard-cover.

I assume you are asking about Hashizo Okawa II, the jidaigeki actor of the 50s and 60s. No, he was only married once, to Mariko Sawamura, a former geisha. You may be thinking of the actress, Yukiji Asaoka, with whom he had a relationship. She talks about their time together in her book, 雪の結晶 (Snow Crystals). She has been married twice. Hashizo chose to marry Mariko after she became pregnant with his child. Seemed to have caused a bit of a scandal, though that sort of thing occurred quite often in the geisha district. Hashizo himself being the son of a geisha. Generally, girl babies were allowed to stay with their geisha mothers, however, boy babies had to be given up for adoption. Mariko chose to leave the life of geisha. Their second son was born a few years later. She has also written a book, ふたりひとつ わたしの橋蔵親分 (My Boss, Hashizo). Hashizo was a good provider and reportedly ensured that much of his fortune would remain to support his family after his death. Both sons are in the entertaiment business one behind the scenes and the younger one an actor like his father. Mariko still speaks about 'life with Hashizo Okawa' at specials events. In fact, she is scheduled to appear at a special memorial event on May 22, 2009. Hashizo would have been 80 this year.
