Sogou Co., Ltd. is one of the largest Japanese department stores. The head office is located at No.3 Fan, No.8 Shinsaibashi 1 Dingmu, Central District of Osaka. It is said that the sale in support of the Yomiuri giant was held before liquidation, because the owner of the former Yurakucho store was the Yomiuri Group. Sogou Department Store once advertised "sogou Network is the link between people, cities and the world". In 1990s, an FM Yokohama broadcasting studio was opened in Yokohama store, which provided hourly time. Under the leadership of Mizushima Yuu Zhi, who was born in Industrial Bank of Japan, he actively launched publicity with the time-honored brand of "Ten in One", and slogans such as "Double Ten in One" (20 branches nationwide) and "Thirty in One" (30 branches nationwide) followed. However, at that time, the land price was rising, and the disputes and debts after land resumption were finally solved by folk regeneration before they could continue to operate. In addition, from Nara branch in sogou (now Nara branch of Ito Yokado), it is said that all subsequent branches have built huge and gorgeous presidential rooms. The entrance is mostly located in a hidden place in the warehouse, and ordinary customers will not notice it. Even the elevators in and out are separated from those used by ordinary customers. It is generally believed that the remains of these bubble economies are one of the reasons why Shihe is in trouble.
