One of Hong Kong's biggest landlords is in talks to enter Japan's resurgent property market as part of parent Jardine Matheson Holdings Ltd.'s pivot toward becoming an investment firm, people familiar with the matter said. Hongkong Land Holdings Ltd. is targeting deals over $1 billion for mixed-use complexes with high-end office, retail and hospitality spaces in prime Tokyo locations, the people said, asking not to be identified discussing private matters. But the company has struggled to secure the right property or a suitable co-investment partner at what remains a challenging time in Japan's investment cycle, they said.
