HOWTO: Installing Japanese Input and Font Setup in Ubuntu 8.04 (Hardy) using SCIM: 日本語
Installing Japanese Input and Superior Font Setup in Ubuntu
This is a guide to setting up Japanese for Ubuntu 8.04 Hardy. It is intended as a complete guide encompassing all elements required for using Japanese on any language installation of Ubuntu. It covers input (SCIM-Anthy) and configuring the Japanese fonts. There are other guides around for older versions of Ubuntu or that use the alternative UIM (see other guide). This guide is intended to cover everything. Please note that Kubuntu requires slightly different steps. Please follow the relevant page accordingly. This is an updated version based on the original 6.10 one, but with some sections changed. Please note that if you follow this guide, your fonts will be reconfigured. This might mean losing some font settings you may have made. With each version of Ubuntu, there are certain changes, this guide is not the same as the 7.10 version.
There are two main issues here:
1.Installing the SCIM input system that will work in a locale other than converting your whole install to Japanese, i.e. you want Japanese input in an English login.
2.The fonts look initially terrible. Therefore a certain amount of customisation is required to make all the Kanji's render in the same style and Hiragana & Katakana to render in a matching style.
Japanese Input with SCIM
This section covers setting up the Japanese input system using SCIM Anthy. This involves, downloading, installing and configuring it so that you can use it in non-Japanese locales (e.g. your system is in English).
Setting Up Repositories
First lets make sure you have the correct repositories installed in order to automatically download the relevant packs. Make sure you have the Universe and Multiverse repositories switched on. This can be done in 'Synaptic Package Manager' under the repositories tab. Also, you need the Japanese repository too. Open the repositories list file:
Add the following line at the bottom:
gksudo gedit /etc/apt/sources.list
Note that you will need to change 'hardy' if you are using a different version from 8.04. Now update your repos with:
deb http://archive.ubuntulinux.jp/ubuntu-ja hardy/
At this stage, you will probably get an error saying that the repository is not validated. Ignore this for now. The following step will correct it. After adding the repository and running the update, you also need to add a keyring for the new location:
sudo apt-get update
Adding Ubuntu Language Support
sudo apt-get install ubuntu-ja-keyring
Go to System / Administration / Language Support and select Japanese. This should install the basics. Make sure you've also turned on support for inputting complex characters.
Making SCIM available under a non-Japanese login
Now you want to make SCIM (Language input system) available in your English (or other language) login and not just the Japanese one. Since 8.04, ubuntu will make it available in GTK applications, but if you want to run non-GTK applications such as KDE or pure X software such as those Java based you'll need to make a few changes. If you are running a US locale, it might work with defaults, but any other locale will almost certainly need registering. First open the scim global settings file:
Add the line:
gksudo gedit ~/.scim/global
The above line adds support for US and UK locales. If you are using a different locale, you will need to change / add the relevant locale. You can find out the name of your current locale by entering:
/SupportedUnicodeLocales = en_US.UTF-8,en_GB.UTF-8
In my case (UK) it returns LANG=en_GB.UTF-8. Add the necessary to the above line.
IMPORTANT NOTE: SCIM is very unforgiving with this line. Note that there is NO SPACE between the "," and "en_GB". If you put a space there, it will ignore everything after. Therefore make sure the following locales are separated by a comma only.
At this stage you'll probably need to log out and back in again. Open a text editor and hit ctrl+space. SCIM should pop up ready to type in Japanese.
Adding handwriting recognition support for looking up Kanjis
After adding the above repository, you should be able to install the 'Tomoe' handwriting recognition addon for scim using:
Unfortunately, Tomoe is set to load dictionaries that correspond to the locale, so if you're not using a Japanese locale, you'll need to create a link to the dictionary manually.
sudo apt-get install scim-tomoe
Where 'en' corresponds to your locale type. In my case (en_GB.UTF-8) it is 'en'. For you, it might be different. You can look it up as mentioned above.
sudo cp handwriting-ja.xml handwriting-en.xml
Now that Tomoe is installed, it is accessible on the SCIM menu under the 'SCIM Command Menu' and listed as 'Handwriting recognition'.
Setting up the system to display Japanese characters properly
OK, now you've got Japanese input installed (hopefully). It might require rebooting xwindows (CTRL+ALT+Backspace). But for me, I really didn't like the horrible fonts that defaulted. Particularly the fact that hiragana / katakana characters are rendered differently from kanjis and the poor quality of smaller sizes annoys me. The main reason for this is that the fonts provided do not always have a full set of kanjis, with default settings the kanjis are rendered as bitmaps and the hiragana and katakana as vectors.
At lower font sizes, it would be impossible to render all the strokes in very complicated characters without blurring and this causes a readability problem. This can be overcome with bitmap alternatives at a low end. Certain strokes are omitted and the shape is actually changed in order to improve readability. It's not simply a case of rendering the same vector in a smaller size. Some true type fonts contain bitmap alternatives that can be automatically substituted at the low end. This is a common approach and is adopted by Windows, MacOS and other electronic devices in Asia such as mobile phones. Here's the next step.
Downloading External Fonts
Unfortunately, I am very disappointed in the Ubuntu selection and you will almost certainly want this to be changed to MSGothic and MSMincho. They contain a superior vector and bitmap selection. These are Microsoft fonts, but they are freely available to use and are actually from a company called Ricoh. They need to be downloaded and installed manually. They can be found at the following page.
So download and extract the files and you need to copy them into the fonts directory. This will need root privileges and is probably easiest done using the file explorer:
That will give you a browser with the right privileges. So copy your downloaded ttf files and paste them into a folder under the fonts tree. I recommend:
gksudo "nautilus --browser"
Rebuilding the font cache
Now we need to rebuild the fonts cache:
Setting up the font order
sudo fc-cache -f -v
OK, so that might well be enough, but I think you'll probably still have your Japanese fonts not running at optimum and the default might be a little ugly. Lets set up the order in which we like the fonts to be selected. Open the “.fonts.conf” file in your home directory:
It should read as follows:
gksudo gedit ~/.fonts.conf
So, save the file and reboot xwindows (CTLR+ALT+Backspace). Now with any luck the order of fonts should have been updated so that the default Japanese type face is actually a clean one first and foremost instead of the ugly first serving. Also it enables the built in bitmap font which can really make kanji's more readable and also enables the bitmap version of hiragana and katakana so that they don't look blurry anti-aliased next to clear bitmap kanjis. For most people this setting will be fine. If you're not happy, by all means leave out the embeddedbitmap setting or change it to false.

To finish things off, I'd suggest making sure in System / Preferences / Appearance / Fonts, you've got subpixel smoothing on and after clicking on details, hinting is set to 'full'.
