They reach Osaka after two weeks of typhoons. After sending the rest of his men back to Yedo, Blackthorne brings Vinck with him, hoping to convince him to embrace Japanese customs and culture, but Vinck just wants to kill Yabu for Pieterzoon’s death.

In exchange for insights into the workings of the Christian daimyos, Blackthorne teaches Uraga (formerly Brother Joseph) navigation, European history, and how to use guns.

A ship filled with Ishido’s Grays brings news that Ishido is waiting to accept Toranaga’s surrender in 19 days and Yabu gets an invitation to the ceremony. The Emperor will also be there. This does not leave Yabu enough time to execute Toranaga’s plan.

Everyone is invited to Ochiba’s birthday party the next day, which prompts Mariko and Kiri to discuss what this means for Blackthorne. Kiki’s baby is growing and healthy, but tens of thousands died in the recent typhoons.

Uraga gives Blackthorne a coded message from Yabu about an official function the next night (Ochiba’s party). Also, Blackthorne should “consider seventy” (904)—the code for getting the ship ready for immediate retreat. Uraga has other news as well: There will be a huge Mass in 20 days for Kiyama and Onoshi, interest rates are rising, and he saw Mariko going to confession.
