Rakuten Sans is a sans serif design designed with a combination of expression and functionality in mind. Like the previous Rakuten corporate typeface, it is a geometric sans serif design: the tapering shape of its spurs is a tribute to that typeface.

The open counters preserve legibility at smaller sizes; and yet the slightly flaring terminals to its curved strokes gives the face sharpness and personality. The upright styles are accompanied by true italic matching fonts, cursive in construction in order to achieve best contrast when used alongside the upright, for instance to create emphasis.
