Competition in Japan's online shopping market is intensifying.
Amazon Japan, which is rapidly growing in the domestic market, has since mid-November expanded the target areas of its Prime Now delivery service, which delivers orders within an hour of receiving them.
Rakuten and Yahoo Japan are offering point-increase campaigns that provide more points in return for purchases, which can later be used to buy goods.
The Prime Now product lineup includes more than 65,000 items, such as food, beverages, daily necessities and home electronic appliances.
Although the delivery service was previously limited to certain areas in the 23 wards of Tokyo, since November 15 Amazon has expanded it to all 23 wards. The expanded service also covers some areas of Yokohama.
