Yes. It requires you to try but not to actually get rid of foreign citizenship. And for dual nationals, there is no legal method or sanction under Japanese law for either forcing you to renounce foreign citizenship or for revoking Japanese citizenship unless you accept a position or employment with a foreign government agency or refuse to sign a (non-binding) declaration of choice.
Yes, and the mechanisms spelled out under Japanese law have no actual impact on foreign citizenship. Those are determined by the laws of the relevant country.
And as you will note a key component of renunciation is that it must be voluntary. The US courts and agencies have determined that compulsion under foreign law (unless you are applying for foreign nationality after the age of 18) by definition can NOT be voluntary and therefore you can not renounce citizenship to comply with Article 14 of the Japanese Nationality Act unless you perjure yourself. In practice consular officers at the US Embassy in Tokyo will automatically ask you if you are renouncing US citizenship in order to comply with Japanese law on dual nationals and send you straight home if you answer in the affirmative.
Which is why sound legal advice is crucial rather than relying on a web search and a simple cursory reading of the statute. Actual law is determined by statute; regulation, regulatory interpretation and practice relating to the statue; and judicial decisions and interpretation of the statute. For anyone in doubt or who is actually impacted by this issue, I would encourage you to consult (as I have done in the past) a Japanese attorney with expertise in this area.
Well, yes, I suppose a know it all attitude works in some quarters. But lets just for a minute act like there are others who know maybe a wee bit more abut some things than we do ourselves. Or not. Up to us all I suppose
About the only good advice in the preceding post is to consult a lawyer. A Japanese one. You know, the sort so known for advising risk.

For those of you that don't live here, that was heavy sarcasm.
With a couple kids in this boat myself, I have spoken with lawyers extensively on this and other aspects of dual citizenship. Bottom line is the law is the law and any actions one takes are their own responsibility.
"In practice..." is hands down the single worst piece of advice ever given. It assumes all future actions will equal past ones. Lets hope readers are more cautious than that.
So folks, take the advice of, "It will be fine, don't worry, I know all sorts of stuff about Japan."
or....
Be your own counsel, and follow that voice to seek or not, as you see fit, further legal advice from a lawyer in Japan.
