This bus terminal, part of the Tateyama Kurobe Alpen Route, is the highest bus terminal in Japan. The terminal, which is the departure point for the Tateyama Highland Bus and the Tateyama Tunnel Trolley Bus, features the largest restaurant on the Alpen Route, a rooftop observation deck, a tea lounge, and more. Restaurant Tateyama, located inside of Hotel Tateyama, offers a variety of quick food options featuring the flavors of Toyama, like their shiroebi karaage-don sarasara-jiru set (fried broad velvet shrimp on rice and soup set). If you mail something from the Tateyama Mountain Top Branch Post Office on the first floor of the hotel, the staff will cancel your postage with a commemorative stamp.
