Tokyo

Tokyo Skytree

Guinness certified it in 2011 and nothing has taken it since. The height was chosen because 634 reads as Musashi, the old name for this stretch of country.

Toyosu Market

Toyosu handles more seafood than anywhere else in the world. The bluefin auction runs for an hour before dawn, and the good viewing deck is balloted.

Meguro Parasitological Museum

Two floors, 300 specimens on show and 60,000 in the library, founded by one doctor in 1953. It costs nothing and takes donations.

Ryogoku Kokugikan

Six honbasho are held in Japan each year and three of them are here. Fifteen days each, and the whole thing is over in seconds at a time.

teamLab Borderless

Rooms with no fixed walls, where the works wander between them and react to you. It out-drew the Van Gogh Museum and holds the Guinness record for it.
