Japanese Ministry of Justice (MOJ) launched new web site which is database of English translation for Japanese Law. This is official translation and very helpful. Good initiative by MOJ and I really appreciate their hard work on this!
The site url is http://www.japaneselawtranslation.go.jp/
However for customs and trade professional, we still have challenges mainly in following points.
1) Export control - Only FEFTL (Foreign Exchange and Foreign Trade Law), Export Trade Control Order, and Foreign Exchange Order are available. There are no English translation for Ministry Ordinance and Notices, which include critical information when resolving operational inquiry from industry.
2) The translation is not for the latest one. For example, the translation of Export Trade Control Order doesn't reflect recent change in Nov. 2008, which should reflect catch-all control for Conventional Weapon.
3) Customs Law - No translation at all! These are under Ministry of Finance, but there is no customs related Law or Order.
MOJ states they continue to add, improve, or update the English translation.
Stay tuned and continue to monitor this web site.
