Thank you for those wonderful sample sentences, especially in the vocabulary sections. A question: are those examples full-on Japanese, i.e. is the combination of kana and kanji what I would see in real life? Or do these sentences, relying on my supposed kanji knowledge, replace some of the kanji with kana to make it easier for me?
And I am not asking about the Furigana; I know I will not encounter those IRL.
Sentences all over Renshuu will usually replace kanji with hiragana or show you furigana until you learn the kanji. There's a setting somewhere to change how sentences display.
99.9% of sentences in "real" Japanese will have a combination of kanji and kana. This is totally natural.
Based on your kanji knowledge, renshuu may hide some kanji and show it in hiragana instead in sentences, but I believe (I have not looked at the default settings for new user accounts in a LONG time), the default is to still show the kanji, but with furigana over it.
But compared to Chinese, there is effectively no way to represent full Japanese sentences/thoughts (unless we are talking about single words, and sometimes, not even then) without both the kanji and kana.
