Japanese is actually much easier to read than
people think. Sure, there are no spaces between
words, but they are not necessary. Because
Japanese uses two syllabaries (not alphabets),
katakana and hiragana, as well as kanji, you
can easily tell where a word ends because the
sentence switches from kanji to hiragana, or
katakana to hiragana. Also, due to the sentence
structure, once you learn the particles like
ha, wo, he, ni, ga and so on, you will
quickly recognise the ends of words.
