When dusk rolls around, you'll want to position yourself well. You won't get a better sunset than the one seen every night over the town's lake. As locals do, you can watch it from Shinji-ko Ohashi, the town's westernmost bridge, but the best spot is south of the bridge, along the road, down near water level in Shirakata Koen, the narrow lakeside park just west of the NHK Building. This is a great place to kick back and enjoy some tasty local microbrews and sushi.
A popular yuhi, or sunset, spot is the patio of the Prefectural Art Museum, visible and adjacent to the park above.
