Kiro is a minimal, simple condensed sans-serif family designed by Ryoichi Tsunekawa, and the whole family consists of 12 styles: six weights from Thin to ExtraBold and their matching Italics.
The range of styles provides flexibility for title, headline, and body text. And the large x-heights gives them legibility and readability. 
The basic skeleton was designed semi-modularly, and the letterform was minimalized by removing their unnecessary stems. Their corners were finished with a subtle rounded effect. 
The minimalized semi-modular design gives this family contemporary urbane taste, and rounded corners make this family warm and friendly. 
Kiro supports almost all European languages: Western, Central, South Eastern Europeans, and Afrikaans. And superior figures, inferior figures, denominators, numerators, and fractions can be accessed by using OpenType features.
