Matsuhime (松姫, 1562 - 31 May 1616) or Shinsho-ni (信松尼) was a Japanese noblewoman who was a member of the Takeda clan, an important samurai family of the Sengoku period.

A mountain pass is named Matsuhime Tōge in her honor due to her having used the path to escape Oda Nobunaga's army.

[1] The Shinsho-in temple in Hachioji (Tokyo) preserves to this day a wooden statue of Matsuhime and the naginata (polearm) she wielded.

According to Kai Kokushi, Shingen devoted himself to prayer for the healthy recovery of one of his ill daughters in 1565; the common consensus is that the girl in question is Matsuhime.

The Kōyō Gunkan states that the Oda-Takeda alliance was threatened in 1567 when Takeda Katsuyori's wife (Ryūshō-in) and Oda Nobunaga's niece and adopted daughter, died.

When Takeda Shingen was 49 years old, he was the only daimyō with the power and tactical skill to stop Oda Nobunaga's race to rule Japan.

After the cancellation of her engagement to Oda Nobutada and the death of Shingen, Matsuhime moved to Takato Castle under the patronage of her brother Nishina Morinobu.

Before he conducted seppuku prior to the fall of the castle, he told Oda soldiers of his prediction of Nobunaga's death, which soon came to pass.

This path was named Matsuhime Toge in her honor for her heroic act of leading an escape to protect the Takeda bloodline.

They fled to many cities before settling at Kinshō-an, a temple in modern day Kamiongatamachi, where many old retainers of the Takeda clan lived.

While living as a nun, it is said that she taught reading and writing to local children in a temple elementary school, did sericulture, and weaved cloth to earn money to raise her three princesses.

There are legends which persist that Nobutada and Matsuhime kept a secret affair with one another in spite of their political differences, but there is so far no proof that these tales could be reality.

Takeshi Nishiyama, a distant descendant of Nobunaga, claimed that the couple eloped and gave birth to Oda Nobuhide.
