As we continue to enhance our maps in Japan, here’s a look at our favorite cartographic features available to add to any map or visualization.

GL rendering for CJK glyphs


Global Japanese labels

All maps have Japanese-language labels available anywhere in the world from our global dataset.

Bilingual labels with formatted text

Display two languages at the same time using a format expression:


map.setLayoutProperty(layer, 'text-field', ['format',
     ['get', 'name_ja'], { 'font-scale': 1.2 },
     '\n', {},
     ['get', 'name_en'], {
          'font-scale': 0.8
     }
]);

Local glyph generation for CJK

Using local glyphs for CJK text instead of embedded fonts can have significant performance improvements for your map. CJK glyphs are detailed and heavy in terms of file size, so we offer a feature to bypass remotely loading fonts and default to a local font that’s already on your user’s phone or computer.

var map = new mapboxgl.Map({
container: 'map',
style: 'mapbox://styles/mapbox/streets-v9',
center: [120.3049, 31.4751],
zoom: 12,
localIdeographFontFamily: "'Noto Sans', 'Noto Sans CJK SC', sans-serif"
});


Vertical layout for CJK text on line labels

When designing labels for roads or other line-based features, you can display your text vertically along the line’s path.
