A rarity even in Japan, this sand museum is based on the themes of sand, time and environment. This facility, adorned with six large and small glass-covered pyramids, was designed by Shin Takamatsu, a world-famous architect with ties to Oda City. Objects and sand from around the world are displayed in the museum, and there is also an area where you can experience sand painting, sand art, and other activities. The main attraction is the enormous one-year hourglass “Sunagoyomi” that measures 5.2 meters high and 1 meter across. It contains 1 ton of sand that slowly marks the time as it trickles through the hourglass. At the Fureai Koryukan annex, you can enjoy four types of glass craft workshops (fees apply).
