What does our logo mean ? (2017-10-13)
Recently I have told you about the meaning of your name. Today I will tell you about our logo. The word "音" in the center of logo is OTO means the sound. The Miazima symbol is same as word "門" (MON) means the gate. It is nealy same "N" symbol in English. The red circle is same as "O" character, it combine with the red M character to become "MON". So, in the logo we have OTOMON !

By the way, in Japanese, as you put the word "OTO" into the word "MON", it becomes the word "闇", you can spell it "YAMI", mean the dark, same as hell. In the mean time, the red symbol in the center of logo have symbol like a sun, the bright side, the heaven. The word "mon" in Japanese means the gate, and also it means the bondary separates 2 worlds, in this logo it means the border line between the heven and hell and "the sound" is in the heaven side. It is same as symbol leading us thinking about the image of phantom in the Opera, the music in heaven and the dark side without it. That is reason why the background color of our website is black.

The "M" word is also the symbol of mountain, the image of red sun raises up on the top of Fuji moutain is always the best symbol of Japan.

Thank you for reading.
