Hi!
I've changed some highway=unclasified
to unclassified (note the double s).
Please make sure to use the correct spelling, JOSM 13170 sometimes forgets all highway types.

Hi!
I've removed highway=* and bridge=yes from way/242893994
What special information did you try to map with them?

Hi!
I've removed highway=water from this way:
way/539626954
What did you try to map with this tag?

Hi and welcome to OSM!
I've noticed this changeset because of the unusual tag highway="tertiary highway"
used on a building. What does it mean?
There is also ele=5.6, I assume you meant the height of the building (height=5.6)
Instead of name=house please use building=house. The name tag should only be used for objects which have a name, it should not describe the object.
There is also a highway=tertiary named "Tertiary Road" next to the building.
The road looks more like a path or track like the other roads nearby.
Hope this helps, happy mapping!

Moin!
Du hast hier highway=street_lamp an einen Parkplatz gehängt. Meintest Du lit=yes ?
way/543274265
Mit highway=street_lamp werden die einzelnen Lampen als Knoten erfaßt.

Hi!
You add highway=street_lamp to a closed way with amenity=parking. I assume you meant lit=yes ?
The tag highway=street_lamp is meant for the nodes where a single lamp is located.

Moin!
Das Tag highway=mini_roundabout ist nur für knoten gedacht, wenn ein (geschlossener) Weg gemalt wird, dann passt entweder junction=roundabout oder evtl. junction=circular und das highway tag sollte hier wohl highway=residential sein.
way/486122334

Hi!
Please check:
What does highway=mini_roundabout mean on these two ways?
way/545077392
way/545077384
I think the ways look like highway=unclassified, but where is the roundabout?

Moin!
Ich vermute, hier sollte es heigth=5 anstelle von highway=5 sein ?
way/532286546

Excuse mon francais.
Je suggère d'utiliser highway=cycleway.
highway=trak est une faute d'orthographe
(trak -> track).

OK, two points
1) trak is probably a typo for track
2) a track is meamt for agricultural vehicles, but this way has an explicit agricultural=no.
I think what you want to describe is a highway=cycleway, right?

Hi!
Please check highway=turning_circle on this way way/173271995.
I guess you wanted to change a different object?

Hi!
I've noticed this changeset because of the typo highway=residental (missing 2nd "i").
I assume that JOSM has saved this wrong spelling and uses it whenever you start typing r e s , so please watch out to correct it. I've changed 23 ways here:
changeset/54325730

Yes, the wiki is not very clear about the destinction of unclassifed and residential, and I am also often unsure which is better when mapping in Japan.
When you follow this wiki: highway=* for unclassified it says
"The least most important through roads in a country's system – i.e. minor roads of a lower classification than tertiary, but which serve a purpose other than access to properties. Often link villages and hamlets."
The given example serves to access properties, doesn't it?

Hi!
I noticed this changeset because of the typo highway=u here:way/543539978
I changed it to residential.
I wonder why you map the residential roads with highway=unclassified?

Hi!
Why did you change the tag highway=path to highway=trak
on this way :way/69082540 ? This tag is only used here and the previous value seems to be appropriate.

Ich habe das unübliche highway=stairs nach highway=steps geändert.

Hi!
Please check: What is meant with highway=mwembeni ?

Wie gesagt, ich kenne mich mit indoor mapping nicht aus. Schwierig ist es, weil man oft mehrere Linien übereinander legen muss und dann ist die Auswahl der gewünschten Linie nicht mehr so simpel.
Ansonsen kann ich nur auf osm.wiki/Simple_Indoor_Tagging
hinweisen und natürlich solltest Du alle Meldungen des JOSM Validators prüfen.

Hi!
Please review: What is meant with highway=kn on way/543293274 ?
Why are the footways in this area not connected to e.g. way/146623134 ? Instead they are connected with (end at) the landuse area.
