Why didn't the seekers...

So as far as I can tell, one of the problems the seekers had was not knowing where the hider was.

At several points this series, the seekers are near to Mt Fuji. Now I reckon that's pretty high. It's as least as tall as Adam standing on Sam's shoulders. You can probably see a lot of Japan from up there.

So why didn't the seekers go up there to have a look around at Japan below them first? I reckon it would have saved a lot of time
