For one, all the important decisions are delegated to Ordinance of the Minister for Economy, Trade and Industry. That is not yet done, so right now people have no clue what kind of tariffs will be in place come July. That of course makes it impossible to write any business plan or request funding for bigger projects.

One other problem is with Article 17, which contains the exception for energy intensive industry. To be precise, each enterprise will apply separately for this status. And they get it if their energy intensity is over 8 times that of the average of all industry of Japan.

That of course is an incentive to *raise* energy intensity if some company is on the borderline. Not compatible with any reasonable energy plan, which all try to raise efficiency.

I am in the process of translating this law into English, please google for “Japanese feed-in law translation” if you are interested.
