The correct response is:
Because Japan thought that industrializing countries of Western Europe and the U.S. would gain a lot of power, Japan felt it needed to industrialize also.
Japan recognized that the industrialized nations were gaining significant power and influence, and to avoid falling behind and becoming vulnerable to imperialism, Japan decided it needed to modernize and industrialize. This drive for industrialization was part of the Meiji Restoration, which aimed to strengthen Japan by adopting Western technologies and practices.
