COUNTER
Japanese count big money in units of 10,000. They don't for instance, have a word for 'million.' -- a million is actually called 100万. Which would be logical if it were written with 万-sized commas: 100,0000 . . . but it's written with rest-of-the-planet commas, like this: 1,000,000. I'm sure some asshole thought he was doing the rest of the world a favor with this compromise, but actually that just makes it more confusing for everyone. Probably it was the same motherless douche who decided to import all the on-yomi from China and get them all wrong.
Anyway.

Lookalikes

Meaning Hint Radical
direction / method / person HEAD
10000 EVEN ON TOP

方 means 'person', so naturally it has a little 'head' stiking up on top - you can think of that as the person's beret!
万 is a number, so naturally it has NO HEAD. It's EVEN on top - which makes sense because 10,000 is an even number.
