There are concerns that the development of this three-stage solid fuel rocket, unusual for space exploration, is motivated by military concerns despite Japan’s non-nuclear policy. Solid fuel rockets are the design of choice for military applications as they can remain in storage for long periods, and then reliably launch at a moments notice.
Seeing how the U.S. cast off Vietnam ans its SEATO treaty obligations, If I were Japanese, I would do the same.

Your have read Tom Clancy's Debt of Honor, haven't you? This type of development is a big part of the "evil industrialist's" plot to have Japan punish the United States for what they did to his family in WW2. Big difference is they use Russian designed ICBM plans bought from the collapsing Soviet Union for their secret ICBMs. Good read, maybe even the best of his books, but if you read it make sure you also pick up Executive Orders. It's basically part 2 of one HUGE novel.
