In November 1999, Kiribati agreed to allow Japan's National Space Development Agency to lease land on Kiritimati (formerly Christmas Island) for 20 years, on which to build a spaceport. The agreement stipulated that Japan was to pay US$840,000 per year and would also pay for any damage to roads and the environment. A Japanese-built downrange tracking station operates on Kiritimati and an abandoned airfield on the island was designated as the landing strip for a proposed reusable unmanned space shuttle called HOPE-X. HOPE-X, however, was eventually cancelled by Japan in 2003.
