Because they were designed that way:

Code:

    {
        // Hiragana
        {L"あかさたなはまやらわぁゃっ"},
        {L"いきしちにひみ　り　ぃ　　"},
        {L"うくすつぬふむゆるをぅゅ゛"},
        {L"えけせてねへめ　れ　ぇ　゜"},
        {L"おこそとのほもよろんぉょー"},
    },
    {
        // Katakana
        {L"アカサタナハマヤラワァャッ"},
        {L"イキシチニヒミ　リ　ィ　　"},
        {L"ウクスツヌフムユルヲゥュ゛"},
        {L"エケセテネヘメ　レ　ェ　゜"},
        {L"オコソトノホモヨロンォョー"},
    },

As for why they were designed that way, the best guess I can come up with is so that it matches the other languages, which use 12 or 13 "characters" per row. I don't know enough about Japanese otherwise to explain why.
