About
Okasan sits at the heart of the Italian-Japanese family group that also includes Otosan and the Hiromi Cake pasticceria. Sushi master Fumio Saito, with more than 30 years of experience, brings deep technical knowledge to a menu of mamma-style Japanese comfort food: gyoza, rice dishes and delicate sashimi alongside traditional nigiri. The Prati location makes it a practical daily restaurant rather than a special-occasion venue, and the accessible pricing reflects that welcoming ethos. Like its sibling Otosan in Trieste, Okasan keeps traditional technique firmly at the centre of everything it does.
Neighborhood & visiting
Okasan sits in Prati, one of Rome's neighborhoods where authentic Japanese kitchens have taken root. The house does not publish an online booking link; call ahead to secure a seat, especially on weekends. Check the posted hours before you go — traditional sushi restaurants often close between service periods.
