The government in its 2022 defense white paper released on Friday included a hypothetical invasion of Taiwan by China for the first time.

If an emergency were to occur in Taiwan, an island only about 110 kilometers away from Yonaguni Island, Okinawa Prefecture, the crisis would also inevitably affect Japan, which is why it is said, "An emergency for Taiwan is also an emergency for Japan."
