This could be a bit easier if your parents still have the Japanese nationality.
Children or spouse of Japanese nationals (same status, so we are at the same level if your parents are still Japanese), may apply for Japanese citizenship after 4 or 5 years of residence in Japan.
In contrast, foreigners married to citizens of most Western countries can apply for that country's citizenship after 6 months to 1 year of marriage, sometimes without any period of residence in the country needed. I know that as I have already inquired for my wife and me (just to compare).
So the "near future" will probably be 5 to 10 years after you have decided to move to Japan. The only way I see to speed this up would be to be adopted by one of your relatives in Japan (e.g. an uncle/aunt).
