That's for a long distance train from Tokyo to Kyushu, about 500km. For that distance the timing is quite convenient. There's actually a train every 3 minutes or so, but it's prudent to wait for an express or limited express train as it will get there sooner. Within Tokyo most of the trains run every 5 minutes or so.
