You know when you find a new song in Japanese that you really want your church to be able to start singing? This video will show you how to add Japanese songs to OpenLP.  AND it will show how to add furigana to the songs! This is especially helpful when you have folks in your church who have a hard time reading all the kanji. 

This wasn’t mentioned in the video, but font choice is very important in making sure the furigana spacing is just right. Here are a few good websites that offer free Japanese fonts that might fit the design and style that you’re looking for.

When you look for fonts, be sure that the font also includes kanji fonts too. They show on the bottom of the font panel what elements are included.
