In this paper I show that there are two types of time-dependent downtrend
in Tokyo Japanese. One of them is a global declination which unfolds
across a wider domain, possibly an Intonational Phrase or an Utterance.
The other is a "tone-bound" declination, which is a new finding in the intonational studies. I propose in my downtrend model that the tone-bound declination lasts until the tonal value of each tone is achieved and it is reset immediately after that achievement.
