The Japanese period and comma are different in shape from English equivalents. The Japanese period is a small circle, and the Japanese comma is a short line written from upper left to lower right.
Japanese periods and commas are placed near the baseline in a horizontal way, while they are vertically placed at the right side. The sentence above is written vertically as follows. Notice that the positions of the period and the comma are different.
Kana: おはよう、あきら。 Pitch: L H H H H L L Romanization: O ha yô , A ki ra . Meaning: Good morning, Akira.
Japanese has the question mark (?) and the exclamation point (!) which are the same as English, but you don't have to use question marks even for questions. If a sentence is a question, which has a grammatical question marker, you can use a period instead of a question mark. I will explain it in a later chapter.
Kana: ほんとう？ Pitch: L H H H Romanization: Ho n tô ? Meaning: Really?
Kana: すごい！ Pitch: L H L Romanization: Su go i ! Meaning: Great!
