JoJo's Bizarre Puns: Nehorihahori
Chapter 68 of Vento Aureo formally introduces the character Ghiaccio. Here, Ghiaccio recalls the order given to him by the Hitman Team, to find Team Bucciarati no matter what. He also recalls the expression they used in the order; however, he finds the expression nonsensical and proceeds to rant about it.
The expression in question varies between different languages. This blog will go over some of these rants.
Note: This list is incomplete, so feel free to add more to this list.
Japanese
Here, Ghiaccio is ranting about the Japanese phrase "nehorihahori" (根掘り葉掘り), which directly translates to "thoroughly" but literally translates to "root digging (and) leaf digging". The phrase is defined by its first half, "nehori" (根掘り, lit. "root digging"), making the implication that something is not done thoroughly until the roots are pulled out. The second half of the phrase, "hahori" (葉掘り, lit. "leaf digging"), is added to create a euphonious Japanese wordplay. However, the reason why many translations don't retain this expression is because there's no such expression in their respective languages that has something to do with digging up roots and leaves to find something.
Ghiaccio is taking the phrase literally and rants about how leaves are not found underground and therefore can't be "dug up".
English
French
Currently, there are no transcripts available here. However, in the French version of the manga, Ghiaccio rants about the French phrase "turning every rock and every blade of grass", and he rants about how nothing can hide behind a blade of grass.
In the anime's French dub, Ghiaccio rants about the expression "move heaven and earth".
