All languages are complex in some way or other. Japanese is rather simple in many ways (e.g., number of sounds, syllabic alphabets) but very complex in others (Kanji, counters, and so on). Spanish too has few sounds, a Latin alphabet, simple accent rules, there's generally only one way to write any word you hear pronounced... but it has thousands of irregular verbs, four regular kinds of verb irregularities, and irregularly irregular verbs. English has more sounds, spelling is a mess, has no diacritical marks so you just have to know how written words are to be pronounced, and has developed or and imported hundreds of thousands of words, but its verb conjugation is simpler than most every major European language. A language without verb tenses can still express complex time relationships -- it's just done differently than in a language with verb tenses.
