Industries in any developing country requires nurturing by the govt. In the case of Japan, it took up too many public works projects since after 1868 Meiji Restoration to support basic industries like cement and steel.78 Billion US Dollar per 341 Billion US Dollar for Bangladesh GDP is too small for early industrial country like Bangladesh, in Indonesia people already crying for deindustrialization when industry growth only for 12 percent and push government to give more incentive for industries and manufacturing company.
For example. the banks of all its small rivers and water channels are protected by steel sheet piling with RC beams at the top. It is virtually many thousand kms of sheet piling. This is how the GoJ supported and nurtured steel, cement and other related sectors like transport as well as providing works to Japanese construction companies who employ millions of people.
