Ichitaroo

There is a long-selling Japanese document creating software called Ichitaro which has its own furigana function with a high accuracy rate of around 98% (based on my opinion). It can add furigana to a 100,000 character document in a matter of few minutes. The price is around 15,000 JPY (about 130 US dollars) and it comes with a Japanese conversion software called ATOK. Once you reach the advanced Japanese level, this product is well worth its price.

👉 Microsoft Word and LibreOffice have furigana functions where you can add furigana on your own. Google Docs does not have this function.
