From the page of the author who compiled OpenOffice.org for arm download the file:
openoffice.org-bin_1.1.4-1_arm.deb
From Debian OpenOffice.org page download the following files:
openoffice.org-l10n-en_1.1.4-7_all.deb
openoffice.org-l10n-ja_1.1.4-7_all.deb
openoffice.org_1.1.4-7_all.deb
ttf-opensymbol_2.0.0-2_all.deb
From Debian OpenOffice.org Debian files page download the file:
openoffice.org-debian-files_1.1.4-6+1_all.deb
From here download libneon23_0.23.9.dfsg.3_arm.deb.
Put all the above files in one directory. I use /mnt/cf/InstallDebian/OpenOffice
Then, run the following:
apt-get install dpkg-multicd
cd /mnt/cf/InstallDebian/OpenOffice
dpkg-scanpackages . /dev/null ][ gzip -9 > Packages.gz
You should see something like this:
...
Wrote 8 entries to output Packages file.**
Then edit the /etc/apt/sources.list file and at the end add a line:
deb file:/mnt/cf/InstallDebian/OpenOffice ./
Then run the following:
apt-get update
apt-get upgrade
apt-get install openoffice.org openoffice.org-l10n-ja
dpkg-reconfigure openoffice.org-l10n-ja
And that's it, it'll run no prob now.
Then start OpenOffice by typing
ooffice
When it comes up go to Tools > Options > Language Setting => Languages
There select Japanese for locale setting and hit OK
Then exit OpenOffice.
Done.
Now when you start it again, it'll come up in Japanese.
