Yes, Shionone Tomonoura Daifuku makes an excellent omiyage (Japanese souvenir) from your Hiroshima and Tomonoura visit. Many shops offer beautiful packaging perfect for gifting, and the daifuku represents authentic local culture. However, since it's a fresh mochi product, it's best consumed within 1-2 days, making it ideal for immediate gift-giving upon your return from Tomonoura.
