We only spent a day in Kushiro and we stayed in the Hotel Taito.
It is a beautiful and quiet hotel and the owner, again, is a bird-lover and it contains a little library containing many bird and natural books. It locates in Tsurui Village (鶴居村)which is very near the Kushiro Wetland. The disadvantage is that you can only make reservation via phone call and they only accept 2-month reservation. We only got the help from Matsuo-san to book the room for us as we did not speak Japanese. However, my family member could reach me using distant call during my stay. I think it was OK if you can try making phone reservation. You can find the necessary information e.g. address, phone no and price etc in its website
http://www.hotel-taito.co.jp/. Breakfast, dinner and hot spring are included in the price. For two of us, it's around 9400 yen per
person, around 800 HK dollars. It is as beautiful as it shows in the website, I must say. I personally love it very much.
I bought an English Kushiro Wetland Guidebook in the hotel as well. It’s in English and I think it contains the information that would be useful to your trip. I can lend it to you. I read from the book that in early March, the crane would leave their feeding place such as Akan and go back to the breeding site in the wetland near the river side looking for a desirable nesting place. Some would continue to stay in Akan due to the sufficient food supply. I noticed that foreigner birders usually suggest to watch the cranes in Otowa Bridge and in Akan International Crane Centre in Winter. In my experience, you can get a very close view there and those would be good places for photographing. However,I am not sure if it is a good place in spring. If you want to lend the guidebook, please feel free to email me
mclisa2312@yahoo.com.hk and make a day or I don’t know if it is possible for me to put it in the office of HKBWS for you to pick up. Hope you can take many beautiful photos to share very us in the trip!
Cheers,
