I told myself to learn Japanese even though it is one of the hardest languages to learn coming from English.
[Obligatory complaint about Kanji.]
I managed to get a hold of Genki. In the Kanji section, it says:
Kanji are Chinese characters which were introduced to Japan more than 1500 years ago when the Japanese language did not have a writing system.
This is a statement I took with skepticism since the erasure of history and culture occured throughout the ancient times. But this would mean the Japanese language did not have a writing system prior to 500 CE.
I had found a website that I probably wouldn't be able to find through a search engine in the future. (Very old looking, goes against established academic canon, will probably be out-competed by newer search-optimized websites).

Regardless, there is no way around Kanji.
日 = "day" or "sun"
I would have never guessed as it looked more like a drawer.
