Fukuoka is an old city with a young outlook. The Japanese metropolis of 1.6 million offers great transport links around Asia and a welcoming environment for start-ups and corporations. Changes to building-height restrictions have spurred a rethink of the CBD – dubbed “the Tenjin Big Bang”. Old buildings are being replaced with new. Among them is Tenjin Business Centre, designed by Fukuoka-born Shohei Shigematsu of OMA architects.
