Loved as it was, the tower had a hard time as a business. In its early years it drew crowds, and at its peak about 1,050,000 people came in a single year. After that the numbers slipped, and by 2005 they had fallen to about 270,000. The operating company at the time ran into financial trouble, and the tower and the neighboring Hikawa Maru ship closed to visitors on the twenty-fifth of December, 2006. The tower was handed to the city of Yokohama, and Hikawa Maru went to the shipping company Nippon Yusen. The city did not let the tower fade away. It decided to preserve and revive it as one of the projects marking the 100 and fiftieth anniversary of the port's opening. Private operators were chosen through a public call, and the exterior and interior were renewed, with earthquake strengthening as well. The tower reopened on the twenty-third of May, 2009. In 2011 it took part in a collection campaign aiming for 50 tons of bottle caps, and the collection box is still there. One curious event is worth knowing about. Occasionally there is a challenge to climb the 335 steps up to the observation floor, instead of taking the elevator.
