In light of the previous post by planemad and MAPconcierge about major road realignment issues in Japan, OSM Japan community is now focusing on fixing roads in Tokyo and surrounding areas.

TeachOSM Tasking Manager for Tokyo. http://tasks.teachosm.org/project/91

The objective is to:

• Realign and merge major highways (motorway, trunk, primary and secondary)
• Create dual carriageways on major highways with link roads and correct oneways

Being the country’s capital, and host to many Japanese mappers, the overall quality of data is very good. But, another pass of review can certainly improve the data.

Come join your hands with Japan OSM community by contributing to this task. The instructions are available in English, Japanese, and Russian, hit me or MAPconcierge if you want to translate in your own language.

Visit http://tasks.teachosm.org/project/91 for details on how to map.

Happy Mapping.
