It will take you longer than one day from Tokyo to Matsumoto castle. When you get there you don't need a guide for the castle.
You would be better to take an organised tour of Japan that includes the castle. Or if you want to do it yourself, catch the train to Matsumoto and check into a hotel.
You are not going to do Tokyo to Matsumoto and back to Tokyo in one day.
