I just want to summarize the “miru 見る is controversial” thing for non-reading linguists: “miru” does indeed become “misaseru” if you add the “-saseru” ending according to modern rules. The controversy is whether it is acceptable to use this form instead of “miseru”, which is a separate verb meaning “show”. As far as I can tell there are two prongs to the controversy: (1) “misaseru” and “miseru” are equivalent, therefore the former is redundant, therefore it should not be used (you wouldn’t say “shisaseru” either, just “saseru”), and (2) “miseru” itself can be analyzed as “miru” + OJ causative suffix, therefore, “misaseru” is an ugly, modern usurper, functionally and semantically identical but aesthetically and morally inferior, and should be avoided. I’ve seen similar complaints about 着せる vs 着させる.

The counterarguments to the above include (1) to some speakers at least, they aren’t equivalent; everyone has “miseru” in their vocabulary, and the fact that some people also use “misaseru” indicates that for them it performs a function that “miseru” can’t, and (2) whatever, dude, living Japanese isn’t bound by your rules and regulations, and these forms sound fine to me.

Soma: Now that you mention it, I’m not sure if I hear the さして in Tokyo or on TV more often. I think it might be universal, though…if I was hearing it only on TV it’d have to be Kansai-ben.

Anyway, good tip. Possibly limited to a view verbs however maybe? Group 1 -る verbs would not work for starters.
