Proverb? "When you have completed 95 percent of your journey, you are only halfway there." Around the Internet, "When you have completed 95 percent of your journey, you are only halfway there" is floating around as a Japanese proverb. A Google search for `Japanese proverb "only halfway there"` gives 12,000+ hits and several Instagram-ready quote photos. None of the first 100 hits cite a Japanese source. What is the actual proverb in Japanese?

I think the standard version is "Who travels a hundred _li_) calls ninety a half", because this is the original form attested in a Chinese chronicle.

There is another quote from a Japanese writer Ryūnosuke Akutagawa, which says "assumes the half of a hundred _li_ to be ninety-nine _li_ ".

Either way, I could not find an exact Japanese source that tells the number "95%". And I doubt that it exists.
