Orientation

Aizu's main railway station is Aizu-Wakamatsu Station, served by JR and the Aizu Railways. The city's attractions are not located within walking distance of the station and are distributed across the city center, with many concentrated in and around Tsuruga Castle Park.

The easiest way for tourists to get around are the Aizu Loop Buses, which connect Aizu-Wakamatsu Station with all of the city's sites of interest. The loop buses operate from 8:00 to 17:30 and depart every 30 minutes. One ride on the Aizu Loop Bus costs 200 yen, while a day pass for unlimited rides on one calendar day costs 500 yen.

Aizu has also a network of regular city buses, although most tourists will not need to use them, as the loop buses are easier to use. Fares for regular buses are dependent on distance traveled.
