Kan in Chinese / Japanese...

勸 is the simplest Chinese, Japanese Kanji, and old Korean Hanja word for encouragement or the act of encouraging someone.

This can also mean: to advise; to urge; to try to persuade; to exhort; to console; to soothe.

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.

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

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.

歡 means joyous, happy, delightful, and pleased.

歡 represents external happiness that may have you clapping and cheering.

Please note: The other happiness/joyful which looks like "喜" is more popular.

歡 is the ancient/old version in China and Japan. After WWII in Japan, they started using 歓. Just let us know if you want this modern version instead of the ancient one.

志道館 is often associated with Shorin-ryu Shidokan (小林流志道館). Do not confuse this title with the newer 士道館 which is also romanized as Shidōkan.

小林流志道館 is the Japanese title Shorin-ryu Shidōkan.

簡 expresses the idea of something simple or the essence of simplicity in life in Chinese.

This can also refer to a simple slip of bamboo for taking notes or writing a letter (especially in Korean Hanja).

Technically this is a word meaning simplicity and brevity in Japanese but it's rarely used in modern Japanese. Therefore, you should probably only select this character if your audience is Chinese.
