Tsunami in Chinese / Japanese...

海嘯 is a common way to write tsunami in Japanese and Chinese (there's more than one way to write the same word).

Note: Can also be written as 津波, 海嘯 or 海啸.

津波 is the most common way to write tsunami in Japanese.

This version should be considered “Japanese only,” as it's very uncommon to see this version used in Chinese.

Note: Can also be the surname Tsuwa in Japanese.

津浪 is another way to write tsunami in Japanese and Chinese (there's more than one way to write the same word).

Note: Can also be the surname Tsuha in Japanese.

波 is the most simple way to express wave in Chinese, Japanese Kanji, and Korean Hanja.

This single character means wave. In Japanese, this is pronounced “nami” which is the same “nami” as used in the word “tsunami” (harbor wave).

恐れ多い is a Japanese word for something awe-inspiring or awesome (in some odd context, it can refer to August).

恐れ多い is probably not appropriate for a calligraphy wall scroll unless you have a specific reason.

The word awesome is misused a lot in English or used too casually. This Japanese word is the real form of awesome, and it kind of means numerous fears and anxiety that you would feel in response to encountering something truly awesome (such as God, a tornado, a tsunami, etc.).

Note: Because this selection contains some special Japanese Hiragana characters, it should be written by a Japanese calligrapher.
