As for Japanese locale ja_JP, following options are defined by default, and set LANG environment as ja_JP.

    LOCALE:     --ja_JP  (raw)
                --ja-JP  (dash)
                --jaJP   (long)
                --jajp   (long_lc)
    LANGUAGE:   --ja     (language)
    TERRITORY:  --JP     (territory)
                --jp     (territory_lc)

Short language option (--ja) is defined in the alphabetical order of the territory code, so the option --en is assigned to en_AU. But if the same territory name is found as language, it takes precedence; German is used in three locales (de_AT, de_CH, de_DE) but option --de is defined as de_DE.

Territory options (--JP and --jp) are defined only when the same language option is not defined by other entry, and only single entry can be found for the territory. Option for Switzerland is not defined because there are three entries (de_CH, fr_CH, it_CH). Territory option --AM is assigned to hy_AM, but language option --am is assigned to am_ET.
