Which areas are part of the 1st Island Chain?

Explanation:
Think of the 1st Island Chain as a western Pacific maritime boundary used in strategic planning to influence naval access. It runs roughly from the Japanese archipelago through the Ryukus to Taiwan and down to the Philippines, forming a belt that helps define where foreign naval power might be challenged or constrained near China’s shores. The areas that fit this chain are Japan, Taiwan, and the Philippines, since they sit along that belt. The Bonin Islands and Guam are not part of the core chain, and the chain doesn’t extend into the Indian Ocean or across the Arctic Circle.
