First Hotels booked and first required equipment bought.
Since my trip starts in January next year, there is still a lot of time to prepare. I enjoy to talk to others about their suggestions for my trip. That way I got a lot of valuable inspirations.
Things are pretty easy for the more "normal" holiday like stays in Tokyo, Kagoshima, Nara and Aomori/Sendai. I will just get there and see what the area has to offer. I know Tokyo already pretty well, so it is already pretty clear what to do. From Kagoshima, I will definitely make a trip to Kumamoto, maybe also to Miyazaki. I'll see when I'm there.
So the main task to prepare now is about the Shikoku trail. There I will be walking the Shikoku pilgrimage - about 1200km by foot. I started reading books about it, to get a feeling how this works. Even so it seems there is already a lot of information about it on the web, most of it is not very helpful and incomplete. Even when I worked through a Japanese guidebook with a friend from Tokyo, more additional questions were raised than answered. Looks like I just have to start and see what happens.
Clearly, the most important thing for this are the shoes. I already spent hours in a shop, trying dozens of different types of shoes. Interestingly, every sales person had a different opinion, which shoe is correct for such a trip. I finally chose the Hanwag Arrow. It is light and is even more comfortable than my sports shoes. Socks are from Smartwool
For underwear I will go with Odlo. I know this brand from my free climbing times from 30 years ago. Some of the clothes I bought at that time I can still wear today. Temperature forecast for February in Shikoku is 2 - 10 degrees. It does rain about 6 days that month. So clothes to keep me warm and dry are very important, especially during the walk along the pacific coast.
For no particular reason, I want to record my walk with a GPS device. The one that was suggested to me is the Garmin eTrex. It will be available in 3 weeks. Technical specs sound really interesting, so it should be also useful after my trip to Japan.
As a camera I will have a look at the Fuji Finepix 600. Since it also is not available, yet, I have to wait. Maybe I even buy it in Japan. That would be a marvelous reason to go to Akihabara ;-)
