Final answer:
Japan's better public transportation system is partly due to A) its smaller size which makes creating an efficient network more feasible.
Step-by-step explanation:
The subject of the question is related to the differences in public transportation systems between Japan and China and the reasons why Japan may have a better system.
One factor could be that Japan, being smaller in size compared to China, facilitates the development of a more integrated and efficient public transport network.
Additionally, Japan's historical focus on industrialization has propelled its technological advancements in sectors such as transportation.
Japan's recovery and economic boom post-World War II led to substantial investments in infrastructure, including public transportation, to support its industrial economy.
Moreover, the geographic and cultural isolation of Japan's mountainous archipelago has allowed it to develop unique solutions to transportation that fit the country's specific needs.
In contrast, while China has seen significant developments in its own infrastructure, it deals with challenges such as the need to connect vastly larger and sometimes newly established urban centers.
Japan's economic strategies have often involved using its geographical position to enhance trade in the East Asian Community (EAC), thus focusing on efficient transport not only domestically but also in the context of international trade.
