the major works in which nakahira employed his ensemble casting method were " gendaikko " (modern children ), a cynical , modern film that was shot in the same year as " doro darake no junjo " and was typical of nakahira , and " hikaru umi " (shining sea ), a film in which yoshinaga , mieko takamine , kinuyo tanaka , masayuki mori , and others appeared . 同年のシニカルでモダンで中平らしい『現代っ子』、それに吉永、高峰三枝子、田中絹代、森雅之らが競演する『光る海』は中平流群像劇の総仕上げ的な作品となる。
there are two types of ironware manufacturing methods during the yayoi period; a cold chisel cutting method that cuts/breaks off iron material and grind to sharpen its edge , and a forging method that create shapes by forging (although a very few cases are suspected with a possibility of the casting method , a furnace that can withstand operation at high temperature is required to melt iron and it is questionable if there was such technology during the yayoi period .) 弥生時代における鉄器の生産には、材料となる鉄を切り・折り取り、刃を磨き出すことによって作られる鏨切り技法と、鍛造により形を作り出す鍛造技法があることがわかっている（ごく一部の例について、鋳造により作られた可能性が示唆されているが、鉄を溶かすためにはきわめて高温の操業に耐えうる炉が必要であり、弥生時代にこのような技術が存在したかどうかは疑問視されている）。
