The Japan Times has published a story about Shun Akida, a reporter who is investigating the tunnels that lie beneath Tokyo and the possibility that there is are hidden tunnels that are being deliberately concealed from the public.

The bulk of Shun’s book covers the development of the subway system and questions the many inconsistencies between maps of the past and present — even those that were contemporaneous. “Even allowing for errors, there are too many oddities.”

Shun claims to have uncovered a secret code that links a complex network of tunnels unknown to the general public. “Every city with a historic subterranean transport system has secrets,” he says. “In London, for example, some lines are near the surface and others very deep, for no obvious reason.”

Sitting on the Ginza subway from Suehirocho to Kanda, he says, you can see many mysterious tunnels leading off from the main track. “No such routes are shown on maps.” Traveling from Kasumigaseki to Kokkai-gijidomae, there is a line off to the left that is not shown on any map. Nor is it indicated in subway construction records.
