Japan is synonymous with technology. For decades, the country has been recognized as a leading force in the production of high-quality tech products, which has created a population of tech-savvy individuals and an appetite for innovation and convenience through technological solutions.  

With that preface, it’s hardly surprising to learn that Japan is the 4th largest e-commerce market in the world, following China, the United States, and the United Kingdom. 

With 119 million of their 126.8 million inhabitants connected to the internet and 74 percent of the online population shopping online, Japan is an e-commerce success story, where local brands, like Rakuten and DMM, create a healthy competition with the international e-commerce heavyweights, like Amazon and Yahoo! Auctions. 

In addition to a tech-savvy population, Japan boasts wealthy citizens with the means to purchase goods online. According to the Ministry of Economy, Trade and Industry, the value of Japan’s e-commerce market exceeded 13.7 trillion yen in 2015 — that’s 124.4 billion US dollars. 

Moreover, thanks to the culture around technology in Japan, the market for m-commerce is large. Even their elderly citizens are known to make mobile purchases

Japan’s Top 10 Ecommerce Sites

While the usual international suspects are present in Japan’s top 10, it is clear that local brands make for serious competition, and Japanese consumers have their own unique trends that do not follow suit elsewhere in the world. 

What really differentiates Japan from other progressive e-commerce markets is the significant popularity of peer to peer (P2P) or customer to customer (C2C) platforms, such as Yahoo! Auctions Japan, Mercari and Rakuma. While these kinds of peer to peer marketplaces are increasing in popularity worldwide, Japan has the highest number of these sites in its top 10, indicating a deep love for these platforms amongst its population. 

Fashion is the largest segment in Japan’s e-commerce market, which is apparent when analyzing the country’s top-performing sites. But besides the traditional e-commerce platforms, the range of auction, second-hand, and hand-made marketplaces, makes for an exciting e-commerce landscape in Japan, where the brands sold on the site may be less important than the function of the site itself.
