Yup, Yamanoue survived that landslide accident. He wrote that letter to Mars. His letter consists of the kanji character for heart, which reveals the weakness of Ropuras(the villain of the story). Yamanoue realizes that Marss emotions and compassion is valuable and therefore, that is where Marss true strength lies. Ropuras captured Yamanoue because he wanted Yamanoue to upgrade him into a stronger robot. However, Ropuras lacks the heart and compassion that Mars has. Therefore, he will never have true strength.
