The is a mountain sightseeing route between Tateyama, Toyama and à Âmachi, Nagano, Japan. Opened on June 1, 1971, it is long, with a difference in elevation of as much as .
The Alpine Route goes through Tateyama (Mt. Tate) in the Hida Mountains with many scenic sites as well as walking trails, including Japan's largest dam, Kurobe Dam. Some stations have hotels around them and are used as bases for mountain climbing or trekking. From the top of the mountain, it is possible to see Mount Fuji on a clear day.
The route is composed of seven different transportation services using five different modes: funicular, bus, trolleybus, aerial tramway, and walking. Three transport lines go through tunnels to protect them from snow: one funicular railway and two bus lines. One of the bus lines is the last trolleybus line in Japan, and the other was converted to all-electric buses in 2018. The bus lines are used because they do not exhaust fumes in the tunnels. During summer, shuttle buses between Toyama and Murodà  are also available.
The operates most lines in the route. Its official abbreviation is TKK. The word kankà  (貫å Â) was coined by Muneyoshi Saeki, the first president of the company. According to him, kan () means "time-space", and kà  () means "outer space", while kan (貫) also (normally) means "to penetrate", as in "to penetrate Tateyama Mountains" and kà  (normally) means "light". The word is a homophone to kankà  (観å Â; "sightseeing"), possibly intentionally.
The Tateyama Kurobe Alpine Route involves many sights and attractions for visitors, including:
Midagahara is a flat walking area filled with flowing plains interrupted by blue ponds. Near the bus stop that returns visitors to Bijodaira back down the mountain is a slightly hidden walking path. Midagahara is accessible from Tateyama Station via the Tateyama Cable Car (7 minutes) followed by Tateyama Kurobe Alpine Route bus (about 40 minutes) that goes in the direction of Murodà  Station.
Shà Âmyà  Falls (the tallest waterfall in Japan) is visible across the valley while traveling along the main road from Tateyama Station to the Murodo Plateau.
The section between Kurobe Dam and à Âgisawa was originally made for construction of the dam, while the section between Tateyama and Kurobeko was for tourists from the beginning.
Today, the entire route serves exclusively as a scenic sightseeing journey through the Japanese Alps, popular with tourists. Most travelers complete the route in one direction, either east to west or vice versa. It can be done in a single day or at a more relaxed pace, with an overnight stay at one of the lodges or hotels along the way.
