When reading texts from websites, we ended up resorting to the rikaichan Japanese dictionary, even though we knew that symbol.

But what is a furigana?

For those who don't know, furigana are those little letters written on top of Japanese symbols. They are usually written in hiragana and are intended to make kanji easier to read.

As everyone may already know, a Japanese symbol can have several different readings, depending on the context or other symbol that accompanies it.

That's why furigana is essential for Japanese learners who don't have a good kanji vocabulary.
