If we look at the merits of comprehensive work consignment to private sector by bill ratio, there were higher percentages of contractors who had a good track record of receiving orders replying, “The publicly offered proposal method for recruiting contractors allows us to create a proposal that makes the most of our company’s know-how,” from which we can infer that the more orders a contractor receives, the more likely they are to be able to experience the merits (Figure 2-2-21).

The comprehensive work consignment to private sector is a way to contribute towards reducing the administrative costs of public entities. Further use of the comprehensive work consignment to private sector must be considered, as we work to make the maintenance and management of social infrastructures as effective and efficient as possible, despite the challenging financial situation. If we continue to commission smaller lots of maintenance, management, and repair work as we had previously, order dumping may occur, bringing down the quality of public works and giving

rise to the possibility of impeding the maintenance and management of the region’s social infrastructure, which makes it necessary to find ways of expanding the scale of project for comprehensive work consignment to private sector. Going forward, it will be important to gain understanding from stakeholders, which includes contractors—with special consideration for local, smaller scale businesses—the purpose and mechanism of comprehensive work consignment to private sector. We must build up examples of the results from these consignments and make sure they are widely known $ ^{Note 48} $ . Once that is accomplished, instead of limiting it to roads and sewage, we will be able to attempt the use of this method in other fields, and even combine several fields—for example road management and river management—and consign the maintenance and management of both fields as a comprehensive project.

## Column Various Funding Methods for Maintenance and Management

In addition to those already discussed, there are several other methods of funding for the maintenance and management of social infrastructures.

‘Naming Rights’ is the right to confer the brand name of a sponsoring business’ company name or product name to the name of a sports facility, or the like. Naming of facilities like stadiums—which have the ability to pull in large amounts of customers—are often very expensive trade deals. The use of naming rights has been spreading throughout social infrastructures, such as the naming of things like roads and pedestrian bridges.

The first time naming rights was traded for a public road was for the two new lines of municipal roads built in 2009, in Iwata City, Shizuoka. They were named, ‘Sakura Kotsu Road’ and ‘LaLaport Road,’ and resulted in about JPY1.5 million and JPY2.1 million of revenue over five years, which was allocated to the road maintenance and management costs.

In Osaka, in order to maintain a safe, secure road facility, for the first time in Japan, they traded the naming rights for the common-usage names of pedestrian bridges. The terms stated that revenue amounts must exceed JPY300,000 annually, for a 5 year period. Currently there are ten pedestrian bridges under such a contract.

Though these contracts result in relatively small revenue amounts compared to sports facilities, the trading of naming rights is one method of funding
