I think it's just a name, nothing deep in its meaning. The figure is inspired by the Japanese mythological figure Maneki-neko.

It's just a name. It does not have any mean. And BTW - maru - is just ending for many male Japanese names (ShikaMARU, OrochiMARU and KidoMARU in Naruto for example).

It's just only a name .. But if you want to give it a meaning then, most likely, the meaning of Fukurokumaru's name is somewhat close to "Fukubukuro" which is the Traditional Japanese New Year Custom in which merchants and shops makes a bag full of their merchandise and sell it for cheaper price .. Fukubukuro means lucky bag ..

There's no such thing as gibberish words....all words have an origin...be it an adaptation of archaic, related or foreign words....or introduced through sheer practical custom and experience.

Anyways, lol

I FINALLY SOLVED THE MYSTERY (i think) of the "6 complete riches"!!

I believe it transliterates into "A Million Dollars" (a fortune of 6 zeros)

$1,000,000 is often slang for ultimate wealth (fuku),

it has six zeros (roku),

a zero is round and represent's "fullness" or "completion" of that digit (maru)

fuku - roku - maru

Note: it may be a coincidence, but wealthy people are sometimes deemed "fat cats"...which is what Fukurokumaru literally is, lol

Some bonus info

Fukurokumaru is written 福禄丸

福 - Blessing, Fortune, Luck (This is also what's on his forehead)

禄 - Allowance, Grant, Happiness, Reward

丸 - Round, Perfection (also as a slang-y term for "money" and a common component in names)

Written on the ingot he holds is 千万両

千 - 1 thousand

万 - 10 thousand

千万　- 10 million or "very many"

両 - Ryou - the old japanese coins that ingots look like

wow, thank you Swisidniak!!!

I love that you translated it! It was really insightful! :)

nice
