The name Fire Water in Chinese / Japanese...

水火無情 is a Chinese proverb that means “fire [and] water have-not mercy.”

This serves to remind us that the forces of nature are beyond human control.

Some may also translate this as “implacable fate.”

五行 is the title of the five elements: wood, fire, water, earth, and metal.

The first character means five, and the second character is simply element(s).

According to ancient Chinese science, all matter in the world is comprised of these elements. One idea presented with the five elements is that when energy is added, the matter is believed to expand. When energy is removed, matter contracts. Oddly, this concept is not far from Einstein's theories and modern science. Just a few thousand years before Einstein.

金木水火土 is a list of the Chinese characters for the five elements in a comfortable order (meaning that they “feel right” to a Chinese person who views this arrangement).

The order is metal, wood, water, fire, and earth.

Note that sometimes the metal element is translated as gold. And earth refers to soil versus the whole planet earth.

地水火風空 is the specifically-Japanese version of the five elements.

This is a little different than the ancient or original Chinese version.

The elements are written in this order:
1. Earth / Terra / Ground
2. Water
3. Fire
4. Wind / Air
5. Sky / Emptiness / Void / Ether

Note: This set of Kanji can also be romanized as “ji sui ka fuu kuu,” “jisuikafuukuu,” or “jisuikafuku.”

These can also be written in the order 地火風水空 (chi ka sui fuu kuu). Let me know when you place your order if you want the Kanji to be in this character order.

地水火風 is a Buddhist term that means “earth, water, fire, wind.”

This is often just referred to as “the four elements.” There is a more common title (the five elements) that adds wood to the mix. These four elements are used in some sects of Japanese Buddhism (not so much in Chinese).

杯水車薪 is a warning against a futile effort.

This proverb literally refers to one who is “trying to put out a burning cart of wood with a cup of water,” or “throw a cup of water on a cartload of wood.” The lesson to be learned is about using the right measure or tool for the job and not wasting your effort if you are inadequately equipped for the task at hand - in other words the postscript should be “go get a bucket or a fire hose.”

五大 is the Japanese title for the five elements.

In Japan, the five elements differ slightly from the original Chinese. Therefore, in Japanese philosophy, you have earth, water, fire, wind, and void (space).

The meaning of the first character is 5, but the second character means great or large. Some translate this as the five majors. 大 is only understood as “elements” when you have 五 in front of it.

In Buddhism, this can be short for 五大明王, or the five great and wise kings.

In Mahayana Buddhism, 四大 represents mahābhūta, the four elements of which all things are made: earth, water, fire, and wind.

This can also represent the four freedoms: speaking out freely, airing views fully, holding great debates, and writing big-character posters.

In some contexts, this can be a university or college offering four-year programs.

To others, this can represent the Tao, Heaven, Earth, and King.

Going back to the Buddhist context, these four elements “earth, water, fire, and wind,” represent 堅, 濕, 煖, 動, which are: solid, liquid, heat, and motion.

四大元素 is the title for the four classical chemical elements (fire, earth, air, and water) in Japanese.

四大 = four great/big. 元素 = elements. So 四大元素 literally means “Four Great Elements.”
