The VR project was created by a production team of nearly 10 members led by Hacosco Inc., a Tokyo-based VR service provider. The team used a drone, high-resolution cameras and a laser scanner in the autumn of last year to capture images of the castle from all angles over a period of about two weeks. After the images were put together, the members put the laser scanner to work to accurately measure the dimensions to recreate the castle more faithfully.
