The present article seeks to review the literature on the historical development of the Japanese accentual system. Whilst some merits of the alternative account of Ramsey and de Boer are recognized, the traditional model of Middle Japanese pitch-accent is defended, and a rebuttal of the arguments against it provided. The traditional model is integrated and corroborated by cross-linguistic and phonation-related arguments, with an eye towards philological evidence. It is concluded that, for the present at least, the evidence in favour of the traditional account of Middle Japanese tonogenesis is more robust and more persuasive.
