What numerology do the eight-character moon branch and the Japanese branch represent respectively?

The earthly branches are yin and static, so the earthy branches will only interact when the above phenomena occur, and the earthy branches generally have hidden stems. Only when punishment breaks through the damage can the hidden heavenly stems have an effect. If there is no relationship between two branches, the branch is static and will not interact with each other. For example, unitary and hai seem unitary, but there is no penalty for breaking through injury between unitary and hai.
