Japanese hypersonic cruise & glide missile progress

Below is an interesting wispywood2344 comment of November 13, 2022:

[Since the October 10, 2022 article] there has been a follow-up report [1] on the news of Japanese long-range missiles. 

According to this report, both the "hypersonic cruise missile (HCM)" and the "highspeed glide missile (HGM) for island defense Block 2" have a range of over 1,000 km. 

This is the first time that the range of a HCM has been reported. 

The range of the HGM was said to be 500 km [2] but this is apparently the range of the "rapidly-deployable" Block 1.

Block 1's range of 500 km realizes "inter-island" firing from Okinawa main island to the entire Nansei islands, but is not enough to cover the Taiwan Strait.

Block 2's range of 1,000+ km will not only realizes "island-to-mainland" firing, i.e., from Okinawa main island to the west coast of the Taiwan strait, but also "inter-mainland" firing, i.e. from Kyushu to Shanghai.
