Thanks again for the tips.
I have a compass, and I now have maps for Daisetsuzan. Don't know if I want to navigate exclusively with them in the middle of a fog storm though! I'm basically praying for good weather, so all this planning doesn't go to waste. Anyway. And I think we're going to try and share a sleeping bag, rather than buying another one just for a couple of nights. So we really need nice weather. :-)
How do you generally do vis-a-vis estimated trail times in Japan?
I normally beat them easily enough, but I'll have a heavy pack this time around, so will need to rest relatively frequently. It's not going to be like my run up and down Fuji last year! It seems there's a campsite on the way to Kurodake, so we'll get there (ensha'allah), see how we're feeling, and decide if we're up for moving on. We'll bring enough supplies for 2 and a half days on the mountain, just in case, I think.
I don't travel with a stove, so no fuel, and no boiling water. I'll check up on my tablets (I don't think they're actually iodine) and see what they're supposed to kill.
Moving on to Shiretoko:
I've found two lovely day hikes that I'm interested in. Probably just one. They are:
Iozan - Can be hiked as a day-hike from the Kamuiwakka waterfalls trailhead. Technically you're supposed to get permission in advance, but I believe you can also just turn up and write your name at the gate. Access is only by shuttle bus, which gives serious time limits. Alternatively if we were feeling nuts, we'd walk on to Mt. Rausu. I think that trail is open? We'd then have to try and hitchhike back to our car though.
Rausu - Can be hiked as a day-hike from Iwaobetsu Onsen. We can drive there, and park the car freely, it seems.
Any thoughts on which mountain might be more rewarding if we were only to do one? I assume bears are likely on either hike.
Shorter hikes include around the 5 lakes, and perhaps something off the 334? I'm a little confused, to be honest. Getting information on hiking in the park seems a little complicated.
