Need more information. My Japanese family arrived in Hawaii - I've found the "The Key to Japanese research is finding the family Koseki which is the family registry that Japanese immigrants brought with them from their villages. The Japanese Consult has an index to passenger lists from 1885 to 1910. The passenger lists are also at the Bishop Museum and the Hawaii State Archives. The Hawaii State Library has a microfilm of card index of passenger lists found at the Hawaii State Archives (might be changes-update since I have prior to 2005)
You can write the Japanese Consult (there is a form) with the family name and what ever information you have. Also the LDS (Mormon research paper on dates records are available for Japanese research. Good luck. I'm still research my family in Japan.
