Japanese investment is essential for Mexico not just because it has represented a viable economic diversification option, but the investments have been made in one of the most significant Gross Domestic Product (GDP) contributing industries. Moreover, it is very prestigious, and it has managed to attach itself to local and global companies which, especially in the Bajío region, consolidate local and regional production networks. One of the features that contribute to the good prestige of Japanese investment is, without a doubt, its capacity to plan for the short, medium and long-term. That means challenges such as government and technological changes are factors that both Japanese firms and different government levels take into consideration to make decisions. In this context, this article aims to reflect on the course of Japanese investment in Mexico for the 2020 years, taking into account its historical background, its current state and the international context.
