Wow. That's pretty remarkable. Actually, Japanese combines three separate script types in one writing system: the semanto-phonetic kanji, two related but functionally distinct syllabaries (katakana and hiragana) and the alphabetic romaji.
Malay has also gone through six or seven distinct scripts belonging to three script types: three historically related syllabic alphabets/abugidas (old Kawi, a later Kawi-based Sumatran script, and early Javanese script), the central Malay bamboo script (and likely, though there is no direct physical evidence, its direct ancestor, a commercial script derived from early Gujarati script), the Arabic-derived Jawi abjad, and finally the Latin alphabet.
Javanese, Bugis and Makassarese also went the same route: first an Indic abugida, then a derivative of Arabic script, then the Latin alphabet, and Makassarese actually went through two distinct indigenous abugidas: Bugis-Makassarese script and another script often called "Old Makassarese" that despite the name was probably younger, being for the most part directly based on a variety nearly identical to the Sumatran bamboo script used by Malay.
