For more than half a century, Japan has been at the forefront of 'big physics', asking fundamental questions about the laws which govern the workings of the universe. Questions of this magnitude require cutting edge technology on a truly massive scale. Over three episodes, Nature reporter Davide Castelvecchi travels across to Japan to get a rare look inside three of its flagship experiments.
Part one: Super Kamiokande
The world's largest neutrino detector
Part two: KAGRA
The world's most advanced gravitational wave detector
Part three: Belle II
The experiment which could revolutionise particle physics
