Around about double. This is the quick way I convert things (not totally accurate but it gets you close).
1000 yen = $10 = £5
So basically you divide the yen by 100 and that gets you dollars, and then half it and you get pounds. It's not perfect, but it's quick and pretty close ^-^
Also, Takeru's in H'evn 037 with AnCafe, and he's super cute
I know we all know that already, but this has pictures of his hair when he had the bun but it was in a nice style. You can see the pictures on photobucket if you search 'SuG'. It's the H'evn Cross Talk.
