What Hasekura said or did to bring about such a result is unknown. As later events tend to indicate that he and his descendants remained faithful Christians, Hasekura may have made an enthusiastic – and to a certain extent, disturbing – account of the greatness and might of Western countries and the Christian religion. He may also have encouraged an alliance between the Church and Date Masamune to take over the country (an idea advertised by the Franciscans while in Rome), which, in 1620 Japan, would have been a totally unrealistic proposition. Lastly, hopes of trade with Spain evaporated when Hasekura communicated that the Spanish King would not enter an agreement as long as persecutions were occurring in the rest of the country.
