Setouchi Sans: How a Custom Ligature Carries a Regional Brand

How Much Should a Custom Typeface Really Change?

Abduzeedo's write-up explains how Blaze Type adapted its existing Osmose sans-serif into Setouchi Sans for a regional destination identity in Japan. The core argument is that a small, deliberate change can do more work than a full new family. Blaze Type refined spacing across weights and built a single interlocking OU ligature that links a closed bowl with an open curve, so the regional brand mark lives inside the typeface itself.

For brand builders, the case is a useful lesson in restraint and in reducing licensing friction across many partners. Identity and type designers will find the reasoning behind the ligature worth studying, especially how it appears in headlines and body text rather than only in the logo. Brand strategists planning multi-contributor identities should read it too.
