As far as I know there is no support in procmail for decoding those
fields.  I have always needed to create rules working with the encoded

Example from some localized mailman filtering:
  * 1^0 ^Subject: [^ ]+ post from
  * 1^0 ^Subject: .*El_envio_a_
  * 1^0 ^Subject: .*Un_envoi_sur_la_liste_
  * 1^0 ^Subject: .*_taraf=FDndan_g=F6nderilen_

Using wildcards for the interesting characters has worked fairly well
with the European languages.  But I have no experience and no
suggestion for your example JP locale though.

You might try the procmail users mailing list for perhaps better
