Why does tokenized Kanji features never contains Hiragana ?

[theGlenn]

I was wondering how come that this 寿司 produces these 名詞,一般,*,*,*,*,寿司,スシ,スシ features and doesn't include すし

Readings are written in katakana (スシ), which can be converted to hiragana (すし) if if that's better for your use-case.
