Discourse analysis of Japanese particles?

Question

Have there been any English language attempts (preferably readily-available) to define Japanese particles from the perspective of discourse analysis? Some of the things I would be interested to see such an analysis of:

• The use of sentence-ending particles such as na, no, ne, yo, etc.
• The use of focus and emphasis particles such as zo
• Whether an explicit subject is represented using wa or ga
• Whether wa/ga/wo are explicitly stated (most common) or are "dropped" and their noun phrases bare in a clause (grammatical in some contexts)

Concerning discourse markers:
Maynard, Senko (1993) "Discourse modality: Subjectivity, emotion and voice in the Japanese language" (John Benjamins Publishing Company) is seminal work.
Newer work can be found in Onodera, Noriko O. (2004): Japanese Discourse Markers: Synchronic and Diachronic Discourse Analysis (John Benjamins Publishing). Check out the reference sections of these books for detailed studies.

Concerning wa/ga (not an issue of discourse analysis):
To my knowledge there is no English language monograph dedicated to this issue. Try Heycock, Caroline (2008): Japanese -Wa, -Ga, and Information Structure. p54-83. (Oxford Handbook of Japanese linguistics, OUP) as a starting point. But please note that the Japanese language literature on this topic is massive.

Concerning the omission of wa/ga/o (not an issue of discourse analysis either):
I suggest you browse Tsujimura, Natsuko (2013): An introduction to Japanese linguistics 3rd. (Wiley Blackwell). She's pretty thorough.
