This rocket is a copy of the American Delta Rocket. Japanese heavy industry heavily relied on our US technology. Why would you have a little girl to do the countdown anyway?
"the copy rocket of a delta rocket" which you say -- the thing of "N1 and N2 rocket" -- ? H-II launch vehicle and a development type H-IIA rocket are developed with technology of Japan. Furthermore, if it says, the origin of American rockets will be Germany (Nazi Germany). PS. probably she is an adult woman as it is surprising (for you). As for Japanese people, growing older is late.

二段燃焼式ロケットエンジンのことでしょう。
燃料や酸化剤をエンジンに送るためのターボポンプを
駆動するためのターボで燃やした燃料(排気)は、
従来はそのまま捨てられていたけど、勿体無いので
もう一度燃やして推力として役立てようってわけだ。
もう一度燃えるのは一次燃焼が不完全燃焼だから。

When Japan decided to develope it there was nobody before Japan.
