Located in the East China Sea between Japan and China, Senkaku Islands belong to Japan since the end of 19th century. That is why the US occupied these islands when the entire Japan became under the GHQ control. China also recognized the Japanese sovereignty to the islands proved by People's daily in 1953 (Senkaku is Ryukyu's islands) and the official map.
However, in 1978, just after geological research was conducted around the area, China started insisting that the islands belonged to China.
Paracel Islands are the similar case of territorial dispute between China and other countries. Chinese submarine submerged into the water and placed the national flag on the sea bottom. This practical occupation could be applied to this time with Japan. As a matter of fact, South Korea did in similar way to land their military soldiers on Takeshima islands. Every dispute over islands could be linked. Therefore, Japanese government shouldn't compromise anytime even when they're stuck at domestic politics or when some retaliations are expected. This is the matter of national identity.
Japan should publicize the Chinese attitude to international society and cooperate with other neighboring countries. But first, Japan should show its own stance to protect the territory before asking support from the US.
