Biography:
He is 40 years old. He's not very smart and rarely expresses any emotions. He is still single and is known to be a miser, as he once even hitchhiked to Kasukabe, Shin-chan's home city, instead of taking the train because he wanted to cut costs. He does not get along well with his younger brother Hiroshi. He lives in the countryside with his parents as a farmer working in the field. His name Semashi literally means stingy (which explains why he was reluctant to spent his money and energy). Semashi was also the paternal uncle of Shinnosuke Nohara and Himawari Nohara.
