千 thousand

as in, "SEND me a thousand yen. "

'thousand' (千) and 'dry out'(干) look the same . ..except the top of thousand is tilted, but the top of <em> dry out </em> is FLAT. So you can recite this fresh rhyme to jog your memory: 　<p> 'I wear a THOUSAND tilty HATS, <p> but I got to <em> dry them out </em> on a surface that is FLAT. '

1,000 yen bill ★★★☆☆ COUNTER
千 (thousand) + 円 (yen/circle) + 札 (card / label / bill) = 千円札 (1,000 yen bill)

any money in paper form is a 'satsu' - a ten dollar bill is a $10 satsu, etc.
