Buses from Aomori to Mount Hakkoda operate around the year; however, Lake Towada is not served by direct buses from Aomori from early November to late April. To reach Lake Towada during the winter months, a detour by train and bus via Hachinohe is required.
Above fees and schedules are subject to change. Be sure to check current yen exchange rates.
Getting around
The small town of Yasumiya is the only major development along the shores of Lake Towada. Yasumiya serves as the area's transportation hub with both the boat pier and the Towadako bus stop. The rest of Lake Towada is largely undeveloped save the occasional residence, hotel and viewpoint, and a few tourist facilities at Nenokuchi for visitors to the Oirase Stream.
Furthermore, there are boat connections between Yasumiya and Nenokuchi outside of winter.
A car is the only option available if you wish to travel around the whole lake. Note that some roads are closed during winter, and that cars are restricted along the Oirase Stream on certain days during the autumn leaf season. Rental car outlets can be found in Hachinohe, Aomori City, Aomori Airport and central Towada City, but note, that central Towada City is located quite distant from Lake Towada.
