The plaque of honor was conferred on Tsunoda by cultural attaché Hossein Divsalar on behalf of the head of Iran's Saadi Foundation Gholam-Ali Haddad Adel.
Japanese Iranologists, Islamologists and professors of Persian language and literature and Iranian Japanologists have played an effective role in introducing both nations to each other, Divsala has said.
Receiving the plaque of honor, Tsunoda also expressed hope that she would take further steps towards introducing Iranian art and culture to those interested in Japan.
She added that over 125 students from across Japan attend her online class, due to the pandemic, to learn Persian.
Already, she has held an online conference on introducing Iranian art of calligraphy.
Meanwhile, some of her works were displayed at an international calligraphy exhibition dubbed Raqs-e Qalam (Dance of the Pen) on the Silk Road in northeastern Iranian city of Mashad on January 24-2.
