Karuizawa Wild Bird Forest
This sanctuary is home to some 80 bird species, including the Japanese white-eye. You can watch from two observation huts along a 2½-km (1½-mile) forest course. To get here from Karuizawa Station, take a free shuttle bus bound for the "Hoshino area," or take the local Seibu Koden bus. Get off at the Tombo no Yu stop and walk about one minute to the park. You can wander around on your own (free), or book a two-hour guided ecotour in English for a charge. Try to book at least a week in advance for English tours.
