It became very easy to share the Explicit Knowledge worldwide because of the rapid expansion of digitization and networking but Japanese people or companies are in the difficult situation because they are not good at using global standard language i.e. English.
But some of manufacturing industry companies (such as automobile and materials industry) and service industry are still competitive. I think these companies business consist of a lot of Tacit Knowledge and their competitors cannot easily copy their values.
In order to energize Japan, it is important to become good at using English but at the same time it is also important to increase and utilize Tacit Knowledge, which is Japanese strength.
