Yamato Transport Co., Japan's largest parcel delivery company, may stop accepting same-day delivery orders from online shopping giant Amazon Japan, company sources said.
Yamato has deemed it difficult to continue such services, as a growing number of orders from Amazon Japan for same-day delivery has forced Yamato workers to deliver more parcels at nighttime despite a shortage of workers. The courier firm intends to gradually decrease the number of same-day delivery orders it takes.
Amazon Japan is expected to rely more on Japan Post Co. and other parcel delivery companies for its same-day delivery services.
At the same time, Yamato's move could spur electronic commerce companies, which have grown rapidly thanks to their convenient services, such as same-day delivery, to review their operations.
A representative of Amazon Japan declined to comment on the company's contracts.
Yamato Transport delivered a record of roughly 1.87 billion parcels in the business year of 2016, up 7.9 percent from the previous business year. The number of parcels Yamato deals with has been increasing since it signed a contract with Amazon Japan in 2013.
