Whoa. The Tsukinos are even richer than I thought.

Apparently, they aren't the only ones.

Tuxedo Unmasked: How Rich is Ami Mizuno?

Well, not only does her mother apparently collect diamonds as a hobby, but the condo mother and daughter Mizuno live in is what’s referred to as a okushon (億ション), a wordplay on mansion (マンション; manshon), from the Japanese word for a condominium.

You see, the Japanese word for 10,000 is man (万) which is a homophone for the first half of the aforementioned mansion. The next highest number counter in Japanese is oku (億), which means 100,000,000. So basically it’s a wordplay to suggest that it’s a super-ritzy condominium nearly no one could afford.

And so on.
