Regarding Amazon's FMN clause in their contracts, the EU Commission is investigating its legality on digital books while other Fair Trade Commissions including that of the UK are looking into the practice in online travel agencies. In Japan, the investigation on Amazon is the first in terms of MFN.
Amazon Japan's PR Manager declined to comment to the Nihon Keizai Shimbun (Nikkei) when contacted on 30 May 2017.
According to sources who know the Amazon warehouses well, Amazon is planning to delete the MFN clause from the contracts for publishers supplying e-books and Amazon Market Place sellers.
The EU Commission closed its investigation on 4 May when Amazon.com of the US submitted a revision plan and a pledge that it will stick to the revision plan for five years.
