Lehmann (1988) proposed ''a survey of the most important aspects of co
mplex sentence formation in the languages of the world,'' that took th
e form of ''generally applicable parameters of clause linkage.'' This
article tries to apply such and similar parameters to the patterns sho
wn by Japanese, whose situation is interesting because of the great si
milarity in structure shown by the majority of its subordinate clause
types among each other, and even with coordinate clauses. This fact so
metimes causes confusion in classification, as happens for the tempora
l V-te form, which is listed as an example of coordination by Hinds (1
986) and Kubota (1989), while Kuno (1973) considers it as a subordinat
e construction, and even farther from coordination than, for instance,
temporal to constructions. The parameters applied help to a certain e
xtent in locating the different kinds of Japanese complex sentences at
different levels on a continuum between what Lehmann calls ''maximal
elaboration'' and ''maximal compression'' of lexical and grammatical i
nformation, corresponding respectively to the coordination of independ
ent clauses and the strong embedding of a subordinate nominalized sent
ence.
