The new technique is called the Taisei Ecological Reproduction System (Tecorep). Instead of using explosive materials, it takes the structure apart from the inside.

Tecorep was conceived in 2008 and it took at least a year and half to be developed. Unlike other demolishing methods, this one also saves energy and reduces carbon emissions by 85 percent, according to the international press.

The first building to be demolished by using the Tecorep method is Tokyo’s Grand Prince Hotel Akasaka, which is the tallest construction in Japan to be demolished to date.


Inside the building, jacks support the roof as floors are demolished from the top down, while an internal crane lowers materials and debris to the ground floor.

The Grand Prince Hotel Akasaka was supposed to close in March 2011 because the building needed significant renovations. But the hotel stayed open three more months, until June 2011, in order to give shelter to Fukushima evacuees.
