niwa 291
2. Vinf.nonpast may be nominalized by no, as in (1) and (2) below.

There is no difference in meaning between ni wa and no ni wa.
3. Ni wa can take not only a Vinf.nonpast but a noun as shown in KS(B),
Exs.(i) and (j). A noun here is a noun of action which can take the verb
sum. There are two types of such nouns: one is the stem of the so-called
sum-verb, such as kenkyu of kenkyii-sum (of Ex.(j)) or the direct object
of sum, such as nagatabi (of Ex.@). If a noun is not a noun of action,
the sentence does not express a purpose, as shown in (3).
