Yes I lived in Japan for a few years and love the transportation system there. The shinkansen is wonderful, but the hyperloop will be substantially faster in door to door time, because hyperloop cars will also transit the local loop system.
Most transportation systems are not designed to optimize door to door time. Even by express train, it's a long trip from Narita airport to Tokyo.
