A VIEW OF TOKYO FROM TOKYO SKY TREE TOWER: NOVEMBER 2, 2011

The catastrophe caused by the M 9. 0 Tohoku earthquake and tsunami on March 11, 2011 and concern about inevitable earthquake disasters in the future served as a catalyst for planning a backup city for Tokyo

ITRBBC: A CONCEPT $180, 000 BEING REQUESTED FOR A FEASIBILITY STUDY TO START THE PROCESS

The plan, URBAN PLAN B, calls for construction of a NEW CITY to be called IRTBBC (Integrated Resort, Tourism, Business, and Backup City) or NEMIC (National Emergency Management International City) on the site currently occupied by the Osaka International Airport at Itami

OSAKA INTERNATIONAL AIRPORT

ITRBBC’s FUNCTIONS • ITRBBC would take on all the functions of Tokyo, the capital, in the event of a catastrophe.

ITRBBC’s CENTERPIECE • The centerpiece, a 650 m-hightower, would house 50, 000 residents and accommodate a work-day force of 200, 000 people from the Osaka region.

WHAT COULD BE THE NEXT EARTHQUAKE DISASTER FOR JAPAN • A difficult question, but -- • It is the question that was being asked long before the March 11, 2011 TOHOKU earthquake catastrophe.
