FAQ

Did the mission achieve its purpose?

The trade negotiations with Spain bore no fruit. With the persecution of Christianity intensifying in Japan as well, Tsunenaga returned home in 1620.

Can you still see traces of the mission today?

You can encounter a reconstructed ship and related materials at facilities in Ishinomaki. The associated documents are also inscribed on UNESCO's Memory of the World register.
