Old Japanese / Traditional Chinese & Korean
萬歲 is the traditional Chinese, Korean Hanja, and ancient Japanese way of writing banzai.
In modern times, the first character was simplified in Japan and China. So you might want to select the other entry for universal readability.
While it has become a popular, if not an odd, thing to scream as you jump out of an airplane (preferably with a parachute attached), banzai is actually a very old Asian way to say “hooray.” The Japanese word “banzai” comes from the Chinese word “wan sui,” which means “The age of 10,000 years.” It is actually a wish that the Emperor or the Empire live that long.
Imagine long ago when the Emperor made a rare public appearance. 萬歲 is what all people would yell to their leader in respect.
So if you like it as a hooray, or you want to wish someone that they live for 10,000 years, this is the calligraphy for you.
Other translations include Cheers! (not the drinking kind), hurrah!, long live [name]!, and congratulations!
To other things with banzai in their names, I am still waiting for the promised sequel to Buckaroo Banzai.
Notes: Sometimes people confuse banzai with bonsai. A bonsai is a miniature tree. They have nothing to do with each other.
