TOKYO (Reuters) - Japan's Fair Trade Commission (JFTC) said on Thursday it has accepted Amazon Japan's plan to improve business practices suspected of violating anti-trust rules.

The unit of Amazon.com Inc (NASDAQ: AMZN) was raided by the JFTC in 2018 on suspicion the company demanded that suppliers should shoulder part of the cost incurred from selling their products at a discount on the e-commerce company's website.

Amazon Japan's plan includes the return of 2 billion yen ($18.85 million) to about 1,400 vendors, the regulator said.
