A Journey of a Thousand Miles in Chinese / Japanese...

千里の道も一歩から is the Japanese version of an ancient Chinese proverb that means “a journey of a thousand miles begins with a single step.”

Some will also translate this as a 1000-mile road starts with one brick (a small amount).

In this case, the real measurement is an ancient Chinese “li” or 里, which is romanized as “ri” in Japanese. It's about half a kilometer, so three 里 would be a western mile. A journey of 333 miles begins with a single step, just doesn't sound as natural.

Note: Because this selection contains some special Japanese Hiragana characters, it should be written by a Japanese calligrapher.

千里も一里 is a Japanese proverb that states “A journey of a thousand miles feels like only one mile.” It is understood that in the proverb, this applies when going to see the one you love.

Note that the “mile” or 里 used in this proverb is an old Chinese “li” (pronounced “ri” in Japanese). It's not actually a mile, as the measurement is really closer to 500 meters (it would take 3 of these to get close to a western mile). Still, 1000里 (333 miles) is a long way.

千里之行始於足下 is a Chinese proverb that means “a thousand-mile journey begins with the first step.”

This proverb figuratively means “big accomplishments come from an accumulation of little achievements made one by one.”

鵬程萬里 is an ancient Chinese proverb used in modern times to wish someone a long and successful career.

It's really about the 10,000 Flight of the Peng (Peng, also known as Roc is a mythical fish that can turn into a bird and take flight).

Zhuangzi or Chuang Tzu

Breaking down each character:
1. Peng or Roc (a kind of bird).
2. Journey (in this case, a flight).
3. 10,000 (Ten Thousand).
4. Li is a unit of distance often referred to as a “Chinese Mile,” though the real distance is about half a kilometer.

Direct Translation: “Peng's Journey [of] 10,000 Li.”
Literal meaning: “The 10,000-Li Flying Range Of The Roc.”
Perceived meaning: “To have a bright future” or “To go far.”

This proverb/idiom comes from the book of Zhuangzi or Chuang Tzu. It tells the tale of a huge fish that could turn into a gigantic bird. This bird was called a “peng” and was many miles long. This legendary size allowed the Peng to fly from the Northern Sea to the Southern Sea in a single bound.

Wishing someone “a Peng's Journey of 10,000 Li” will imply that they can travel far without stopping and will have great success, a long career, and a prosperous future.
