Amazon has started offering its Dash Buttons in Japan, a few months after the product expanded outside the US for the first time with launches in the UK, Germany, and Austria. The Wi-Fi-connected gadgets allow you to order products from their associated brand just by pushing the button.

Each Dash Button costs 500 yen ($4.40) in Japan, but you'll get a 500 yen discount the first time you use it, so the button itself is basically free. As with elsewhere, the buttons are exclusive to Amazon Prime members.

The Japanese launch includes products from 42 brands ranging from Gillette razor blades and Ariel detergent to Suntory mineral water and Calbee granola. I am considering getting one for Wilkinson ginger ale.
