Osaka beats London to the 'turning a canal into a public pool' idea

Remember the plan to turn the Regent's Canal into a swimming route for commuters? That was the runner-up in a competition to find a new green space in London to compete with New York's High Line park, so it isn't actually going to be built. If you want to see a canal conversion in real life, best head to Japan.

The city of Osaka actually wants to turn a canal in the middle of its tourist district into a huge public swimming area. It's not going to be as ambitious as the 13.8km LidoLine (which would have connected Little Venice in the west to the Limehouse Basin in the east), but the Dotonbori Canal swimming area's 800m would, The Japan Times reports, be the largest public outdoor swimming in the world.

Right now, the Dotonbori Canal has a boardwalk running alongside it that was installed recently as part of a "cleaning up" of the area to turn the rundown former theatre district into something more family-friendly. Taichi Sakaiya, an author and economist, is behind the idea -- a man ominously known as "the Godfather of Osaka" for his influence on local politics. A private company has been formed to fund the conversion of the canal by 2015.

The canal itself -- 12m wide -- won't just be fenced off halfheartedly at either end, it will actually be completely converted into a pool. Concrete walls will separate it from the waters in the rest of the canal at either end, with pumps circulating the clean, chlorinated water.

Apparently, fans of local baseball team the Hanshin Tigers like to jump into the canal when celebrating victory, but when the pool comes in they'll have to start paying for that privilege -- ¥1,000 (£6.41) for the first hour, then an extra ¥500 (£3.20) for each hour after that. The total cost of converting the canal into a swimming pool is estimated to run to ¥3bn (£19.2m).

However, the idea isn't exactly being welcomed by Osaka residents, as the Dotonbori Canal has something of a reputation for pollution and grime. The Japan Times quotes local residents who are sceptical that the authorities will be able to keep drunken patrons leaving nearby bars from pissing into the canal as they tend to do at the moment.
