Seisonkaku whose previous name "Tatsumigoten" was built for wives of the Maeda family. It was first built on grounds of 1500 tsubo (a Japanese unit of area of land equal to about 3.3 square meters) including row houses and storehouses, although only 500 tsubo remains today. The wife of the 12th lord Takako, who was later called Shinryu-in after shaving her head, played a significant role in supporting the Maeda family after her husband passed away, given that the wife of the 11th lord had already died, and the 13th lord Nariyasu was still too young to bear the responsibility of succeeding to the family headship. In spite of the fact that Takako was only 38 years old, she summoned up the courage to support the succeeding generations, shouldering the heavy responsibility of the Kaga dynasty. One of the most important missions of wives in those days was to preserve the family's heritage and pass it on to the following generations. Much of the historical heritage was lost during turbulent periods between the last days of the Tokugawa shoguante and the beginning of the Meiji era. Although the Maeda family was no exception, the efforts of Takako and other Maeda wives combined with good luck have made possible the preservation of some of the most important cultural assets.
