Family genealogy about my relatives the Maeda Family

I'm looking for my family genealogy on my mother's side, the Maeda Family from Tokyo, Japan. My mom's father's name is Heihachi Maeda and his father's name is Toyokishi and his mother's name is Sen. Heihachi's brother's and sister's are Hiroji, Fusanosuke Nakai, and Yoshio.

On my visit to Japan in 1988 (it might have been fall 1987), my mother and I visited the city of Kanazawa (Ishikawa Prefecture) where I learned that during the feudal period Kanazawa was under the Maeda Family. I am not sure if this is my family, however, I was told that my grandfather Heihachi was the direct descendant of the Maeda rule (equivalent to a governor).

If anyone has information on where I can research my Japanese family history or find information about my family please message me on facebook.com/perri.mink
