These are three of my favourite English, online shops in Japan.
1. Kenko.com Japan's no.1 e-drugstore is now available in English, yay! Lots of baby goods and supplements.
2. Items can be purchased from Akachanhonpo online at Rakuten. The descriptions have been translated using an auto-translator so they can be quite confusing. Also available in Korean and Chinese. For all Rakuten products in English click here.
3. Sammy's is a new and used clothing store for kids of all ages, from newborn to 12 years old.
