Proposals for conventions
国土交通省の「国土数値情報」(KSJ2) のインポートを考えています。ライセンスがPublic DomainやCC-BY-SAではありませんが、約款では出典の明記のみが利用条件になっているのでCC-BYに近いです（ウィキペディアのCopyrighted free useと同等）。賛否やご意見等をお願いします。現在、鉄道データをOSMの形式に変換するスクリプトを作っています。
- I added KSJ2 to the import catalogue and then started KSJ2 page and its railway data page. -- Tatata 11:34, 5 March 2008 (UTC)
I spent a lot of time about 6 months ago (alongside other contributors) making sure that the coastline of Japan was complete and error free. It now looks like it has dissapeared completely when viewing the Osmarender layer. Does anyone know what's happened? Thanks - Daveemtb 09:12, 26 September 2008 (UTC)
Multi Layer Buildings and highways
Please have a look at my proposal about levels.

Hi, Im making Garmin .img Contour maps at 10m detail. Im using the 1x1 degree ComputerTeddy sized files from GroundTruth, and i have them available, linked to my Wiki page http://wiki.openstreetmap.org/wiki/User:Acrosscanadatrails#Japan_Work Should these be added to the local city/town pages as a resource? (these maps can be used as a transparent overlay to the latest OSM data IMG file. --acrosscanadatrails 13:23, 7 June 2010 (UTC)
Problems with coasts
Cooperation with Wikipedia

Removing "WikiProject" prefix
The name of the pages related to the Japan mapping project would be "Japan" (name of place) instead of "Wikiproject Japan", as recommended by the wiki conventions. It is a change that I have already made in United States, Canada, Spain, Australia, New Zealand, South Africa, Denmark, Norway, United Kingdom, Italy, Germany, India, Russia, France, and all Spanish-speaking countries on this Wiki (and more).
