There are people who tend to write yamato kotoba (Japanese words having their origins in the time before the introduction of Chinese characters) in hiragana or katakana. In fact, to write yamato kotoba excessively in kanji is often regarded as a thing that is done by undereducated people who try to feign to be well-educated (and by gaijin who have a smattering of Japanese and erroneously think sprinkling their Japanese writing with many kanji is a sign of being knowledgeable about Japanese).
Do Japanese people tend to know which words predate the introduction of kanji? That's a lot more etymological knowledge than most English speakers have...
