This is e-commerce data for Japan. You can find the poulation, internet users, internet penetration here as well as the localised domain extension, official language and other statistics to help build an overall picture of the general online economics of Japan.
Japan was one of the first countries in Asia to take to online shopping. The market was reportedly already worth $3 billion in 2000. By 2014 this had grown to $104.7 billion.
According to some estimates there are as many as 76 million online shoppers in Japan and is the biggest ecommerce market in Asia after China.
Japan, like a few other Asian countries, is unique in which online marketplaces, search engines and social media sites it uses. Making it slightly harder to enter the market as a foreign merchant without much experience in such areas. It is also very important to translate the websites properly, as 99% web pages viewed in Japan are in Japanese.
