Titia Bergsma (Leeuwarden, 13 February 1786 – The Hague, 2 April 1821) was a Dutch woman who visited Dejima Island, Japan, in August 1817 with her husband, Jan Cock Blomhoff.
[1] Under the Tokugawa shogunate's sakoku policy Japan was extremely secluded.
The Dutch and Chinese were allowed to visit the country, but only for trade, and no women were permitted.
Five weeks later when the shōgun Tokugawa Ienari became aware of her presence, he ordered that Titia and the wetnurse Petronella Muns had to leave.
