Quality of Japanese translation seems low

[yukidaruman]

As a Japanese MoD player, I really appreciate adding Japanese language support.
However, as soon as I switched language to Japanese, I noticed many problems of its quality.

1. grammatically errors

(see list below for some examples)

2. Too many typos

For instance, the sentence "自分のブッロク数が２つのプレヤーの合計ブロック数より多くにカラークレイズを終了する" contains 2 typos: "ブッロク" ("ブロック" is the correct word) and "プレヤー" ("プレイヤー" is the correct word).
I found 17 "プレヤー" in the translation file.

3. Full-width and half-width texts

In some sentences full-width characters (e.g. ＡＢＣ１２３) is used in some translations, but not in others.
e.g., "MODを入手する", "ＭＯＤ設定"

4. Spelling/translation inconsistency

"コントローラ" and "コントローラー" have the same meaning "controller", so they should be unified.
e.g., "チュートリアル", "説明" (a word for "Introduction")

5. Some expressions that should be translated are not translated, and vice versa

"afk" is not a widely-known word in Japan. How about using "退席中" (away from desk) instead of "afk" as Japanese Steam uses "退席中" for Away?
Also, "ping" is translated into "ピン" or "ピング", but "ping" itself is a well-known word as a technical term, so there is no need to translate it.

--------
Here is the some examples of incorrect translations (too many to write a complete list).

original English	original translation	translation of "original translation"	suggested translation	reason
You can now use this character in online games as long as it's in your Steam Inventory	Steamインベントリーに入っているさえこのキャラは使用可能となりました	---	Steamインベントリーに所有している限り、このキャラクターを使用することができます。	wrong translation of "as long as"
Ruin those friendships!	中割れする!	---	友情を破壊する!	"中割れ" is a word for "broken spine of a book". I think "友情を破壊する" is common translation for "ruining friendship(s)"
This is how long the match will last. 1 minute means roughly 3 rounds.	マッチはどれぐらい時間かかるか、 １分でほぼ３ラウンド	---	試合時間。1分はおよそ3分に相当します。	grammatically incorrect
BOMB TAG HAS A 93.48% CHANCE OF RUINING FRIENDSHIPS.	ボムタッグは９３．８％の確立で友達の仲を壊している	---	ボムタッグは93.48%の確率で友情を破壊する。	"確立" (establish; verb) and "確率" (probability; noun) have the same pronunciation, but they have different meanings
hold for {1} seconds	{1} 秒を押してください	press on {1} seconds	{1} 秒間押してください	wrong translation of "for"
Due to driver problems,	ドライバーの問題によると	According to driver problems	ドライバーの問題により	wrong translation of "due to"
Credits	エンドロール	End credits	クレジット	"エンドロール" is specified for "end credits"
Confirm mod publication	ＭＯＤは本当にアップロードしますか？	Mod confirm its publication	MODを本当にアップロードしますか？	grammatically incorrect
Play a game with 3 other friends	３つの友達とゲームする	Play a game with for	3人の友達と一緒にプレイする	"つ" is used to make plural form of something (not of a people/person)

Last but not least, thank you for all of your effort to make the awesome game.

Accept my friend request right now, as I have something that you MUST translate (MoD related)!
Youll also get something out of this ;D
