Retek Inc has established a new Tokyo-headquartered operation, Retek Japan KK, to promote its leading-edge retail systems solutions in the Japanese market. The company has named Hiroshi Yamashita chairman of the board of Retek Japan K.K. "The Japanese retail market has experienced significant challenges in the last five years," said Ian Johnston, president of Retek Asia Pacific. "As the world's second largest retail market, Japan presents a strong market opportunity for Retek. While building stronger relationships with our existing partners and clients in the region, we felt this was the time to formalise our presence in Japan, allowing us to better interact with existing and future retail customers."
