The M+ Outline Fonts Project develops a superfamily set of several families: 4 families with proportional Latin, 3 with fixed-halfwidth Latin, and 2 with fixed-fullwidth Japanese Kana variations.

The Rounded M+ Project develops versions of the M+ Fonts with rounded terminals.

This set, Rounded M+ 1c, are fonts with proportional Latin and fixed-fullwidth Japanese, and 7 weights from Thin to Black. The Kana have traditional slightly curved strokes. The Latin is optimized to be well-proportioned for text typesetting.

8,546 glyphs. This is Version v1.059g, released upstream on 2015-05-29, and slightly modified by Google Fonts. Now released under the SIL Open Font License.
