A big push began to promote environmental restoration in Japanese coastal zones. Tokyo bay is one of dense populated bay in eastern part of Japan. To facilitate an economical utilization and an environmental conservation in balance, a habitats creation project in urban canal area has been implemented. The facility had two 4m×8m pools with 0.5m depth sandy bottom on the rocky terrace of sea wall. These pools had a potential for a habitat of juvenile fish (gobies) and benthos. Partnership type collaboration was employed to make citizens active participation in the project supported by scientist and local governments. Special designed monitoring methods entertained participants of the project, and proofed high potential of the facility as good habitat for fish and benthos.
