The area was also known for its window displays, an example of modern marketing techniques. Everyone visited so the custom of "killing time in Ginza" developed strongly between the two world wars. Most of these European-style buildings disappeared, but some older buildings still remain, most famously the Wakō building with the now-iconic Hattori Clock Tower. The building and the clock tower were originally built by Kintarō Hattori, the founder of Seiko. Its recent history has seen it as a prominent outpost of Western luxury shops. Ginza is a popular destination on weekends, when the main north-south artery is closed to traffic since the 1960s, under governor Ryokichi Minobe. Many leading fashion houses' flagship stores are located here, in the area with the highest concentration of Western shops in Tokyo. It is one of two locations in Tokyo considered by Chevalier and Mazzalovo to be the best locations for a luxury goods store. Prominent high-end retailers include the American company Carolina Herrera New York, French companies Chanel, Dior, Louis Vuitton and Saint Laurent, Italian company Gucci and Austrian brands Swarovski and Riedel. Flagship electronic retail stores like the Sony showroom (which closed in 2017 and new building would open in 2022) and the Apple Store are also here (Ginza 2 chome). The electronics company, Ricoh is headquartered in the Ricoh Building in Ginza. The neighborhood is a major shopping district. It is home to Wako department store, which is located in a building dating from 1894. The building has a clock tower. There are many department stores in the area, including Hankyu, Seibu, and Matsuya, in which there are many shops: grocery stores, restaurants, women and men clothes, sports wear, and jewellers etc. There are also art galleries. Kabuki-za is the theater for kabuki, one of Japanese traditional playing, and locates on between Ginza and Tsukiji. The building was opened in 1889 and has been reconstructed several times because of war and fire. The present building was built in 2013. Each Saturday and Sunday, from 12:00 p.m. until 5:00 p.m., the main street through Ginza is closed off to road traffic, allowing people to walk freely. This is called or "Hokoten" for short, literally meaning "pedestrian heaven". There are some people who do street performance such as magic and playing instruments.
