Japan's new law on the choice of law is now in effect. It supersedes the law known as the "Horei Law." The new law is entitled the "Ho no Tekiyo ni Kansuru Tsusoku," meaning "Law on the General Rules of Application of Laws."
It will have a significant effect on international family law cases concerning Japan, as well as in commercial matters.
The law is available in English on my website at http://www.international-divorce.com/horei_law.htm
