Tokyo Takarakuji Dream Palace, Lottery museum in Kyōbashi, Japan.

Tokyo Takarakuji Dream Palace is a lottery museum in Kyobashi, Chūō, Tokyo, first opened in December 1981 in Uchisaiwaichō and moved to its current location on 5 January 2004. It serves as the drawing venue for the national number-selection lotteries Numbers, Mini Loto, Loto 6, Loto 7 and Bingo 5, and for Tokyo Metropolitan lotteries, with 30 seats set in front of the stage.

The museum first opened in December 1981 in Uchisaiwaichō, Chiyoda ward. On 5 January 2004 it moved to Kyōbashi, reopening with largely renewed facilities and displays so it could serve more fully as a base for sending out lottery information, as prize types had diversified.

The hall stages the public drawings of the national number-selection lotteries — Numbers, Mini Loto, Loto 6, Loto 7 and Bingo 5 — as well as Tokyo metropolitan lotteries, with 30 seats set before the stage for spectators. The name Dream Palace frames the visit around the moment a winning number is drawn.

The museum is in Kyobashi, Chuo ward, and admission is free. It opens 10:00–19:30 on Mondays, Tuesdays, Thursdays and Fridays, 10:00–19:00 on Wednesdays and 10:00–18:00 on Saturdays. It is closed on Sundays and public holidays, and from 29 December to 3 January.

The museum displays rare historical lottery tickets and winning slips that show how designs and rules changed over the decades. This collection gives visitors a rare look at the visual details that shaped lottery games through time.
