“You are thinking too much. You need to trust yourself to do the right thing.”
―Hanzo to Koko[src]

Hanzo is a white and blue bullet train who is the leader and mentor of Speed Fleet.


Hanzo is the fastest chugger from Japan. Mentor to Koko, Hanzo is sleek, streamlined, and has a photographic memory. He believes there is no greater honor than transporting passengers quickly, but always safely, to their destination. Respectful, dedicated, and precise, Hanzo encourages fellow Speed Fleet chuggers to be the best they can be through rigorous practice. As well as always extremely punctual.

Technical Details[]

They ran Tokyo between Nagano, until Hokuriku Shinkansen until Kanazawa in 2014.


Hanzo is painted white with blue linings and blue and black linings on the top. His battery boxes and bogies are gold.
