Vacationing in Hokkaido this year is your best bet since the yen has fallen quickly over the last two months. I enjoy visiting the annual summer carnival where I go on the thrill rides and eat sushi, soaking up the nice Christmassy atmosphere. The sun has been dazzlingly hot so you might just as well have a good long soak in an onsen, soaking up the sun. In fact, I've just got out of an onsen and am drying myself off and dressing. My cousin is also drying himself on a towel and getting dressed.
