Hakucho

Hakucho (also known as CORSA-b before launch) was Japan's first X-ray astronomy satellite, developed by the Institute of Space and Aeronautical Science (then a division of the University of Tokyo). It was launched by the ISAS M-3C-4 rocket on February 21, 1979 and reentered the atmosphere on April 16, 1985.

It was a replacement for the CORSA satellite which failed to launch due to rocket failure on February 4, 1976.

Hakuchō (train)

The Hakuchō (白鳥, Hakuchō) and Super Hakuchō (スーパー白鳥) are Japanese limited express train services which operate between Shin-Aomori and Hakodate via the undersea Seikan Tunnel. The services are operated by East Japan Railway Company (JR East) and Hokkaido Railway Company (JR Hokkaido) respectively. The services commenced on 1 December 2002, initially operating between Hachinohe and Hakodate, coinciding with the opening of the Tohoku Shinkansen extension from Morioka to Hachinohe.

Hakuchō

The Hakuchō services operate between Shin-Aomori and Hakodate using refurbished JR East 485-3000 series 6-car EMUs, extended to 8 cars during busy seasons. Services operate at a maximum speed of 140 km/h (85 mph) on the ATC-controlled section of the Seikan Tunnel, with the fastest services between Shin-Aomori and Hakodate taking 2 hours 8 minutes.

The Hakuchō name actually dates back to 1960, as the name of a service which ran from Osaka to Aomori until March 2001. The name was reused for the new services starting in 2002 by popular demand.
