The reason I moved to Sapporo I moved here this March from Tokyo. One of the reasons I moved here is the hay fever of ceder pollen. I heard there is white birch in Sapporo, luckily I don't have that type of allergy yet. They also say the period of white birch pollen is shorter than ceder pollen in Tokyo. There were 2 expected places for me to avoid ceder pollen, Hokkaido and Okinawa. I couldn't find affordable monthly apartments in Okinawa over the internet. And I was looking for houses, because I was doing house-renting-business, I thought there were much more reasonable houses for sale in Hokkaido than in Okinawa, so I thought I might have a chance. I looked for houses, bought one, renovated and rented it. That's major part of what I was doing in Sapporo this year. Actually, I don't like crowded places in Tokyo. Susukino or O-dori is a little similar to Tokyo, but much better, I guess.
