This jigsaw puzzle is based on a photo taken during a major renovation of Super Kamiokande that started on June 1.
It shows Masayuki Nakahata, the director of the Kamioka-Institute for Space Particle Research, who takes the shutter with a remote control while the water level in the tank is about half and he is on a rubber boat and checks the photomultiplier tubes around him.
It is 500 pieces, which is 200 pieces more than the first 300 pieces. Since the size is about twice, it is more difficult.
