No temporal gap exists between Nanjing and Hiroshima, making them prime candidates for a fully integrated co-working model. Project handoffs are non-existent; instead, teams in both regions can collaborate concurrently, bridging a key economic driver in Nanjing, China supporting distributed technology coordination, regional supply chains, and localized client-facing communication channels. and an emerging operational base in Hiroshima, Japan facilitating high-bandwidth remote engineering workflows, asynchronous information loops, and professional services.
