For just 10 days (11/1 ~ 11/10) Nishitetsu will run a daily bus service between Tenjin and Tosu, coinciding with Tosu Premium Outlet’s winter sale. The bus route is regularly operated on weekends only (Sat. and Sun.), but for this period it will run twice daily on weekdays (departing Tenjin at 9:00~ and 11:00~; Departing Tosu at 15:30 and 17:30) and four times daily on weekends and public holidays (departing Tenjin at 9:00, 10:00, 11:00, and 12:00; Departing Tosu at 14:30, 15:30, 16:30 and 17:30). The trip takes around 45 minutes one way, and a return ticket is available for a discounted price of ¥1,000 (usually ¥730 one way). Advance booking required by phone (0120-489-939) or online (http://www.atbus-de.com/). The ticket price also includes a discount coupon for Tosu Premium Outlet, which is handed out on the bus and can be exchanged at the shopping information center.
