Goddess in Chinese / Japanese...

女神 is Goddess from English or Dea from Latin in both Chinese and Japanese.

The literal meaning:
女 = Female or woman.
神 = Spirit, deity, soul, or saint.

觀世音 is the longer and perhaps more formal title for the Buddhist deity known as the Goddess of Mercy or Bodhisattva of Compassion.

The longer title of this bodhisattva is Romanized in the following ways:
Mandarin Chinese: Guanshi Yin, Kuan-shih Yin.
Japanese: Kanzeon.
Sanskrit: Bodhisattva Avalokitesvara.
Korean: Gwan-se-eum.
Vietnamese: Quan Thế Âm.
Thai: Prah Mae Kuan Eim.
English: Bodhisattva of Mercy and Salvation, Goddess of Compassion, Buddha of Mercy, et al.

Please view our more common and shorter version, “Guan Yin” before you make a decision. Also, note that the first character has a slight variation in Japanese. If your audience is specifically Japanese, you may want to select that version.

觀音/観音 is the Buddhist deity known as the Goddess of Mercy or Bodhisattva of Compassion.

In Chinese, the proper name of this being is Guan Yin. There is some debate as to whether Guan Yin is female. The argument comes from some scripture that suggests Buddhist deities take on the male form. Others say that Guan Yin has no sex. And still, others are okay with the female representation of Guan Yin.

This bodhisattva is also known or Romanized in the following ways:
Mandarin Chinese: Guan Yin, Kuan Yin, Kwan Yin.
Japanese: Kannon, Kwannon.
Sanskrit: Bodhisattva Avalokitesvara.
Korean: Gwan-eum.
Vietnamese: Quan Âm.
Thai: Kuan Eim.
English: Bodhisattva of Mercy and Salvation, Goddess of Compassion, Buddha of Mercy, et al.

Note: The first character has a slight variation in Japanese. If your audience is specifically Japanese, you may want to select that version.

天照皇大神 is the title for Sun Goddess or Amaterasu Oomikami in Japanese.

Rare Chinese Buddhists/Shitoists may be familiar with this (so I have included the Chinese pronunciation above) however, this should generally be considered a specifically-Japanese title.

Besides Amaterasuoomikami, this can also be pronounced/romanized as Tenshoukoudaijin. There are several similar ways to write Sun Goddess in Japanese, so don't be surprised if you see different forms on the web, etc.

アプロディーテー is the Japanese title for Aphrodite (Greek goddess of love).

Note: Because this title is entirely Japanese Katakana, it should be written by a Japanese calligrapher.

維納斯 is how the name for Venus, Goddess of Love, is written in Chinese characters.

艾福洛迪特 is one of a couple of ways the name Aphrodite, Goddess of Love is written in Chinese characters.

In Chinese, 美神 means Goddess of Beauty.

The first character means beauty or beautiful.
The second character means spirit (can also mean god, goddess, or soul).
Some will use this as a short way to say, “Beautiful Spirit.”

This has a similar meaning in Japanese but is used more often as a female given name in Japan. As a Japanese given name, it can be pronounced Mikami, Mikan, or Binasu.

観音 is the specifically Japanese version of Bodhisattva of Compassion or Guan Yin.

In Japanese, this is pronounced Kannon and occasionally spelled Kwannon. The Chinese version is a bit more commonly seen in Asia. However, in Japanese, there is a slight variation with the first character.

Some time ago, a camera company in Japan named their company after this Buddhist deity. That camera company is still known as Canon (they chose a “C” instead of a “K” when they Romanized this name).

観世音 is the more extended and more formal Japanese version of Bodhisattva of Compassion or Guan Yin.

In Japanese, this is pronounced Kanzeon. The Chinese version is a bit more common in Asia, but in Japanese, they use a slight variation of the first character. Choose this version only if your intended audience is specifically Japanese.
