Industry

■Industry Kitakyushu City got its start from government-owned Yahata Works in 1901, and has developed as one of the four major industrial zones in Japan.

Nowadays the city takes advantage of the accumulation of industry to upgrade the existing industrial technology, and promotes the entire industrial structure to upgrade and soft economy.

Hibikinada area ■Kitakyushu Eco-Town project aiming to be an ecological metropolis Since July 1997, the city has been promoting the Kitakyushu Eco-Town Project, aiming to take a leadership role toward the realization of a sustainable and evolvable society on an axis of the promotion of the environment/recycling industry. The project is based on the alliance among citizens, enterprises, and government that has been developed in the process of overcoming environmental pollution. The project is also based on the technologies, human resources, and industrial infrastructure the city has cultivated as “the town of manufacture” as well as the systematic international environmental cooperation structure having experience for more than 20 years.

Higashida area ■Higashida area new town development In the Higashida area, a “land readjustment project” is implemented utilizing large idle sites owned by enterprises, aiming to promote functional integration of commercial, office and residential quarters to ensure new town development. A “Yawata Higashida green village project” is promoted through cooperation among the industrial, public and academic sectors to develop an environment-conscious town, as a model of world’s ecological metropolis that Kitakyushu City aims to be.

What is CASBEE Kitakyushu?

CASBEE Kitakyushu is a type of “Comprehensive assessment system for building environmental efficiency” that combines nation level assessment based on CASBEE for New Construction (brief version) and assessment specific to Kitakyushu with prioritized points.

Academic experts and people from related departments discussed in the board to extract corresponding items from CASBEE for New Construction (brief version) as prioritized points.
