Japanese IO

This Chrome extension works in concert with Japanese IO (https://www.japanese.io) and brings easy access to dictionary lookups, readings, kanji and example sentences to help you read Japanese web pages. Notice that this extension requires a free Japanese IO account, which can be created from the extension after it has been installed. Paid feature upgrades are available. Word lookups are stored in your profile and you can review and study this vocabulary on the Japanese IO website.
