According to Zhituo Finance APP, a government source stated that on Tuesday, the Japan Fair Trade Commission conducted an on-site investigation of the Japanese subsidiary of amazon (AMZN.US) for allegedly violating the Antimonopoly Act.

Sources said that the amazon subsidiary is suspected of improperly urging sellers to lower prices on its e-commerce website in exchange for favorable placement of their products on the site.

Sources indicated: "There are concerns that the Japanese subsidiary of amazon is pressuring sellers to reduce prices in an unreasonable manner."

The Japanese subsidiary of amazon did not immediately respond to requests for information regarding the email about the raid.

Reports last week indicated that with european antitrust regulators filing lawsuits based on landmark rules, amazon may face an investigation from the EU next year regarding whether it supports its private label products on its online marketplace.

Japanese regulators previously raided the japanese subsidiary of amazon in March 2018 due to the company's alleged request for suppliers to bear part of the costs incurred from selling discounted products on the site. Authorities accepted a plan from the japanese subsidiary of amazon to improve its business practices in September of that year.
