Feeling of Bliss in Chinese / Japanese...

至福感 is “feelings of bliss” in Japanese.

A breakdown of the Kanji in this title:
至福 (shifuku) beatitude; supreme bliss.
感 (kan) feeling; sensation; emotion; admiration; impression.

欣 is the type of happiness that you feel on the inside. It is the feeling of being released and delighted as well as being in a state of contentment. 欣 is more the internal happiness that perhaps only shows by the smile on your face. It can also be translated as “to take pleasure in” or “to rejoice.”

Note: 欣 is often used in compound words - especially in Korean Hanja.
As Japanese Kanji, this is so rare, that most Japanese people are not aware of its existence.

快樂 or joyfulness is an inner sense of peace and happiness.

You appreciate the gifts each day brings. Without joyfulness, when the fun stops, our happiness stops. Joy can carry us through hard times even when we are feeling very sad.

快樂 can also mean pleasure, enjoyment, delight, cheerfulness, or merry. In some ways, this is the essence that makes someone perceived as a charming person.
