"It is 10000 yen."
Starting at 万, numbers always begin with 一 if there is no other preceding number. This does not count for 百 and 千. (though you can still write 一 in front of them to put emphasis)
100 - 百
1000 - 千
10.000 - 一万
hope that helps!
Can you please mention how the kanji for 10000000 is spelt? Thanks in advance
Then why was it accepted before without the "一”? Like when we need to write "１１,０００", I could write "万千” without the "一“ and it was accepted.
I was wondering about that! Some of them use the ichi, but some don't. Is there a rule for this?
Yes; I'm pretty sure the 一（いち） is needed before numerical denominations starting at 万（まん） and up if there is no other preceding number.
Just didnt count enough zeros. Guess i have to go back to that lesson on zeros
Yeah, why do we write the character for one in front of the character for 10,000, but the characters for ten, hundred and thousand dont need it?
The way I figure out 万 is draw an invisible line four digits to the left. Now look at the left side and ignore the rest for now. If it is 10000 then you would draw the line between 1 and 0. On the left there is only 1 so you have 一 and because it is a million you add 万. If you have something like 12340 then we would have 一(because the line still draws between one and two) 二千(for the number of thousands there are) 三百(for the number of hundreds) and 四十円（for forty yen) all together it would be 一万二千三百四十円. I hope that helps some
