Ramen in Noboribetsu Onsen

Noboribetsu's landmark ramen shop serves up fiery red 'jigokudani' noodles that would make the local oni (devils) proud. Entry level is a totally manageable kick; you can add ¥50 to step it up a notch, all the way to 10. (Warning: there are far more celebrity signings on the walls here than photos of customers who have successfully finished level 10 bowls.)
