Considering that Amazon Japan is the world's third-largest Amazon marketplace, it is massively overlooked by most Amazon sellers. This means of course that those who get past the barriers to entry face a lot less competition! And lower competition means easier sales and higher profits. 

Having solved the issues of language in listings and ads, the next issue to solve is importing into Japan.  Again, with shipping times from China measured in days not weeks and within an effective VAT rate of only 10%, compared to the usual 20% coming into the UK or even higher in some European Union countries, there are many attractive aspects to exporting to Japan.

But it does help to have a native guide or at least one who really understands the practical steps needed to import into Japan. Enter John Cant of Rising Sun Commerce.  John Cant has been using his Japanese cultural insights and connections to help Amazon sellers from the UK and North America to sell successfully in Japan for several years now.
