Ya Kun Kaya Toast, often colloquially known just as Ya Kun, is a Singaporean chain of mass-market, retro-ambience cafés selling toast products, soft-boiled eggs and coffee. Founded by Loi Ah Koon in 1944, Ya Kun remained a small family-run stall for decades, but has expanded rapidly since Loi's youngest son headed the business in 1999. The chain has over fifty outlets, mostly franchised, across 14 countries, and is a Singaporean cultural icon, known for its traditional brand identity and conservative, people-centric corporate culture.
