You have successfully added your business to our database, but because OSM-Carto does not currently render "amenity=dojo" specifically, it is not visible on the map with an icon and name.  Perhaps if you talk to the developers of OSM-Carto, they may be able to help you find a solution.  See <https://wiki.openstreetmap.org/wiki/OpenStreetMap_Carto> for more information.
