I can not read japanese manual on man command on UTF-8.

japanese manual is converted from EUC-JP one by flowing.

#install eucJP one
pkg_add -r http://home.jp.freebsd.org/%7Ekogane/JMAN9/ja-man-doc-9.0.20120115.tbz 
#convert
cd /usr/shere/man
cp -r ja ja_JP.UTF-8
find ja_JP.UTF-8 -name '*.gz' -exec gunzip '{}' ';'
find ja_JP.UTF-8 -name '*.[0-9]' -exec nkf -Ew --overwrite '{}' ';'
find ja_JP.UTF-8 -name '*.[0-9]' -exec gzip '{}' ';'
nkf -Ew --overwrite ja_JP.UTF-8/whatis

Fix: 

You need new groff(v1.21) in this workaround.
So, at first make install new groff via ports.

And do flowing patch on man
This patch simply replace system groff with new one,
and add -D option.

#I don't know well, but anyway  it works.
