About SEIKO HOUSE

Seiko’s predecessor, Kintaro Hattori opens a shop selling and repairing watches and clocks in Ginza 4-chome in 1894. At that time, the founder, Kintaro Hattori, insisted on installing a clock tower on the roof of the building as a service to the people of Ginza.
Later, as a symbol of Tokyo’s reconstruction after the Great Kanto Earthquake, a new building was completed on this site in 1932, and it, too, featured a clock tower. For almost a century it has stood through disasters both natural and man-made, and has become a familiar landmark in Ginza. Today, the Wako building, with its iconic clock tower, is perhaps the most easily recognizable symbol of this world-famous shopping district.

In 2022, to mark the 90th anniversary of this edifice, Seiko will launch a new project, building on the legacy of this historic location, the very origin of the company, to provide a platform dedicated to Japanese technology and craftsmanship. Here, at SEIKO HOUSE, we will focus not on the past, but on the future, looking at how cutting-edge technology and the eternal spirit of Japanese craftsmanship will create a more exciting and more sustainable world in the years to come.

In order to achieve this goal, we will redevelop the main Wako building in Ginza, which is owned by our company, rename it SEIKO HOUSE, and turn its upper floors into a base for promoting the legacy, appeal, and future possibilities of the Seiko brand.
In addition to better utilizing this historical site where one can sense the flow of Time, we will the top three floors with the latest equipment to take greater advantage of the facilities and space in this unique building.
