G-Dan in Chinese / Japanese...

ダン is the name Dan in Japanese.

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

丹 is the most common transliteration to Mandarin Chinese for the name Dan.

二段 is a Japanese Kanji word that literally means “second degree.”

二段 is the second black belt rank in Japanese martial arts.

The first Kanji means two or second in Japanese.

The second Kanji means step, grade, rank, or level.

二段 can also be written as 弐段. This version just uses a more complicated Kanji for the number two.

三段 is a Japanese Kanji word that literally means “third degree.”

三段 is the third black belt rank in Japanese martial arts.

The first Kanji means three or third in Japanese.

The second Kanji means step, grade, rank, or level.

四段 is the title for 4th Dan, a rank used in many schools of Japanese martial arts.

初段 is a Japanese Kanji word that literally means “beginning degree.”

初段 is the lowest black belt rank in Japanese martial arts and the game of Go.

The first Kanji means first, new, or beginning in Japanese.

Other ways to translate this title include “lowest grade” or “first grade.”

六段 is the Japanese title for the 6th Degree or 6th Level.

This applies mostly to martial arts and earning the title of a 6th-degree black belt.

The first character is simply the number 6.
The second character is “dan” which is often translated as “degree” in the context of Japanese martial arts. 六段 means grade, rank, level. When a number is in front like this, it refers to a senior rank in martial arts or games of strategy such as go, shogi, chess, etc.

In Japanese martial arts, this usually represents the first-degree black belt rank.

It can also be like a linguistic stair step of “more, much more, still more, all the more.” It can also be a step, rung, level, or rank.

Also sometimes used in the context of Buddhism to mean “first step” or “first stage.” This might presume the first step towards enlightenment etc.

五段 represents the 5th Rank or 5th Degree (5th Degree of black belt) in Japanese martial arts.

This can also be the 5th rank in other fields such as chess play (Japanese “Go”) etc.

七段 represents the 7th Rank or 7th Degree (7th Degree of black belt) in Japanese martial arts.

This can also be the 7th rank in other fields such as chess play (Japanese “Go”) etc.

師範 or Shihan is a Japanese term, often used in Japanese martial arts.

In typical Japanese language, it can refer to a teacher or instructor. However, in martial arts, it's often an honorific title for an expert or master instructor.

Example: In Aikido the title can refer to someone with the rank of 7th dan. But other schools use it to mean a master who has earned the right to award black belts.

This term is also used in Chinese, where it refers to teacher-training or the art of teaching by example. It's used within the proper name of certain types of universities in China.

鼈 refers to a species of turtle.

鼈 is Trionyx Sinensis.

鼈 refers to different turtles in different languages. See individual language notes below:

Japanese: 鼈 means “snapping turtle” or “mud turtle.” But rarely used as a single Kanji like this in Japanese.

Chinese: 鼈 means soft-shelled turtle. A specific species, Trionyx Sinensis is native to Asia.
In China, this species is related to the “wang ba,” a soft-shelled turtle sometimes known in English as a banjo turtle (due to its long neck, and general shape). Unfortunately, there is a word, “wang ba dan” which means the egg of this species of turtle. That term has come to mean “bastard” in Chinese (a turtle hatches from an abandoned egg, and does not know who his mother or father is). 鼈 is not a good selection for a wall scroll if your audience is Chinese.

In Korean, this character can be pronounced (though most Koreans would have to look it up in a dictionary). It has not been in common use in Korea for at least a few hundred years.

General notes: You may notice that the bottom half of this character is the same as some other turtle-related titles. That bottom half is actually an ancient character that means “toad.” Though not seen in this way today, most turtle-related characters hold the meaning of “a toad with a shell” in their ancient origin. That toad character is rarely used alone anymore but you can see what it looks like in the image to the right.

布施 is the Buddhist practice of giving known as Dāna or दान from Pali and Sanskrit.

Depending on the context, this can be alms-giving, acts of charity, or offerings (usually money) to a priest for reading sutras or teachings.

Some will put Dāna in these two categories:
1. The pure or unsullied charity, which looks for no reward here but only in the hereafter.
2. The sullied almsgiving whose object is personal benefit.
The first kind is, of course, the kind that a liberated or enlightened person will pursue.

Others will put Dāna in these categories:
1. Worldly or material gifts.
2. Unworldly or spiritual gifts.

You can also separate Dāna into these three kinds:
1. 財布施 Goods such as money, food, or material items.
2. 法布施 Dharma, as an act to teach or bestow the Buddhist doctrine onto others.
3. 無畏布施 Courage, as an act of facing fear to save someone or when standing up for someone or standing up for righteousness.

The philosophies and categorization of Dāna will vary among various monks, temples, and sects of Buddhism.

Breaking down the characters separately:
布 (sometimes written 佈) means to spread out or announce, but also means cloth. In ancient times, cloth or robs were given to the Buddhist monks annually as a gift of alms - I need to do more research, but I believe there is a relationship here.
施 means to grant, to give, to bestow, to act, to carry out, and by itself can mean Dāna as a single character.

Dāna can also be expressed as 檀那 (pronounced “tán nà” in Mandarin and dan-na or だんな in Japanese). 檀那 is a transliteration of Dāna. However, it has colloquially come to mean some unsavory or unrelated things in Japanese. So, I think 布施 is better for calligraphy on your wall to remind you to practice Dāna daily (or whenever possible).
