Hiroshi Okubo, Executive Director of CBRE Japan Research tells World Property Journal, "Overall vacancy rate continued to drop in Tokyo in August, and the market remains tight with occupiers seeking to upgrade and - or expand their space. Some of the new buildings being completed with vacancy in recent quarters is not so much due to weak demand as developers becoming more aggressive on rents, and these spaces are indeed steadily being filled up, higher rents notwithstanding."
