Have you considered contributing to #OpenStreetMaps? It's like Wikipedia but for maps - a map that everybody can edit! Today, the NSW Address Import project added thousands of addresses for West Pennant Hills, Warrawee, and West Pymble.
If you know those areas, check it out and start mapping!
@Antanicus hmmm? Which bug? I don't know about this? If you mean the main map on OSM.org, you can check the openstreetmap-carto project
@rory I hope it will be by the time I travel to Japan... I've been advertising OSM to all my friends for months on end, it would be a big fail if I had to fall back to proprietary maps when traveling :D
@thinkMoult Few apps I think should be mentioned:
https://f-droid.org/en/packages/de.westnordost.streetcomplete/ (surveying app)
https://f-droid.org/en/packages/net.osmand.plus/ (general application, has advanced editing support)
@thinkMoult I have contributes to OSM quite a bit in my area :)
It's my go-to mapping project since I've gotten my Garmin GPS
