In the period of warring states, the most well known Christian woman is Hosakawa Gracia who was baptized in the great influence of Takayama Ukon.
The real name of Hosakawa Gracia was Tama who was the daughter of Akechi Mituhide and married Hosokawa Tadaoki,the lord of Miyazu.
Akechi Mituhide was one of the powerful warriors following Oda Nobunaga. He was ordered by Oda Nobubaga to go to the front of the battle with Mouri in Chugoku district to support Toyotomi Hideyoshi.
Akech Mituhide dispathed Kameyama Castle in Tanba, leading 13 thousands soldiers,but he suddenly turned their soldiers to Honnouji Temple,where his lord Oda Nobunaga stationed,and finally destroyed Oda Nobunaga.
The news of the rebellion by Akechi Mituhide arrived at Hosokawa Tadaoki who had led a satisfactory life with his beautiful wife Tama.
Since the incident of Honouji Temple,the position of Hosokawa Tadaoki became delicate because he had the daughter of the rebel as a wife.
Akechi Mituhide sent a letter to Hosokawa Tadaoki,asking that Hosokawa family should obey Akechi Mituhide.
The position of Hosokawa Tadaoki split between the loyalty to his lord Oda Nobunaga and the conspiracy with his relative Akechi Mituhide.
After all,Hosokawa Tadaoki rejected the invitation of Akechi Mituhide and attacked the branch castles of him,and allied with Toyotomi Hideyoshi on the side of Oda Nobunaga. 
One of the problems was the treatment of Hosakawa Tama,a wife of Hosokawa Tadaoki.
If left a daughter of the rebels as she was, Hosokawa Tadaoki himself would be seen a collaborator of the rebellion.
Although he loved and attached to her so much, he couldn't help divorcing her,now that her father Akechi Mituhide rebelled against his lord Oda Nobunaga.
Tama and her followers went into seclusion in a lonely village of Mitono in the mountain of Tanba.
Akechi Mituhide entered Syouryouji Castle where Tadaoki and Tama had married two years before,and prepared the battle against Toyotomi Hidesyohi just quickly returned from the front line of the battle against Mouri.
Tama secluded in Mitono was worried about both welfare of her father Akechi Mituhide and her husband Hosokawa Tadaoki and had fallen in the anxieties of her family and her future.
The force of Akechi Mituhide was inferior in number and defeated by Toyotomi Hideyoshi, the actual successor of Oda Nobunaga,and killed on his way to his castle in Sakamoto.
The Sakamoto Caste burnt down and two elder sisters of Tama died,resulting in a collapse of Akechi Family.
Tama was left alone, holding in his heart a pain of parting with his husband and children. In the midst of her grief,the teachings of Christianity penetrated in the heart of Tama.

Only small rock showing the site of the castle is remained near the Miyazu Port.
Shouryuuji Castle is known as the castle in which Hosokawa Gracia married Hosokawa Tadaoki.
She left Sakamoto Castle,the base of her father Akechi Mituhide, and came to this castle by a palanquin. Both bride and groom were 16 years old then.

  In March 1584,Tama left Mitono with a permission of Toyoomi Hideyoshi who had became a ruler of Japan after the death of Oda Nobunaga and entered the residence of Hosokawa family located at Tamatukuri in the south of Oosaka.
Hosokawa Tadaoki chreshied and attached her as if she were a treasure barely taken back,and she was accompanied with many servants by Tadaoki's order.
On top of that,she was banned to leave the residence even one step. In the confined life like a jail, she was burdened with her sickly son.
At that time, she was moved by the story of his husband's friend Takayama Ukon and visited at a missionary in Osaka.Thereafter,she held a longing for Christianity.
But the order of the prohibition of Christianity was issued in 1587,the rumor spread that missionaries would be expelled.
There was now way of being baptized for her in such a confined life. So,she decided to take a unusual means.She was baptized in her residence by a servant Maria who had learned the way of baptism from a missionary.
This was the birth of Mrs.Hosokawa Gracia.

Hosokawa Tadaoki got to know the matter when he retuned from Kyushu Expedition,and flew into a furry on the matter. But his severe fury couldn't deprive of her faith in Christ.

But Hosokawa Gracia rejected to be taken a hostages and made her servants kill herself.
