The Egawa Family Residence (Egawa-tei) is located in Izunokuni City, Shizuoka Prefecture, and served as the residence of the Hatamoto and Daikan (magistrate) during the Edo period. As a designated Important Cultural Property of Japan, it is a precious historical site that preserves traditional Japanese architectural styles. The grounds feature several significant structures, including the main house with its expansive earthen floor (doma), multiple storehouses, gates, and shrines that form a complete historical landscape. It serves as a direct window into the history of the Nirayama Daikan office, which was a political center during the Edo period.
The Egawa family is a lineage of the Yamato Genji clan, spanning 42 generations over 900 years. During the Edo period, they served as Hatamoto (high-ranking samurai) and held the position of Daikan for 11 generations over 273 years. The successive administrators focused on maintaining regional order and civil administration, achieving a period of stability where no peasant uprisings occurred. Notably, the 36th generation head, Tarozaemon Egawa (Tantan), is celebrated for his contributions to Japan's modernization, including the construction of the Nirayama Reverberatory Furnace (a UNESCO World Heritage site), the building of Japan's first Western-style sailing ships, and the implementation of smallpox vaccinations. This residence has been carefully preserved alongside documents that reflect this profound historical legacy.

The complex consists of seven buildings, including the main house, study, Buddhist altar room, East Storehouse, fertilizer storehouse, armory, and the main gate. The main house's earthen floor is particularly impressive, spanning approximately 162 square meters (50 tsubo), offering a sense of daily life from the Edo period. Visitors can observe architectural details like the marks of traditional hand-axes (cho-na) on the ceiling beams. The grounds are integrated with nature, featuring ponds, groves of Nirayama bamboo, and the 'Miho-sha' shrine. The collection of tens of thousands of documents and artifacts related to the Egawa family also forms a vital part of the experience.
The residence reveals different charms throughout the seasons. For example, during the 'Gusoku-biraki' in early January or the 'Oeshiki' festival in mid-November, the traditional stoves (kamado) in the main house are lit, offering a rare glimpse into historical life. Visitors can also experience the use of traditional tools during specific commemorative events. While most visitors enjoy a leisurely walk through the grounds and gardens during the day, visiting during seasonal ceremonies or special exhibitions provides a much deeper immersion into the history of the region.

Visitors can learn about Edo-period architectural techniques and lifestyles firsthand. Standing in the vast earthen floor of the main house and looking up at the grand structural framework allows one to feel the scale of historical construction. Walking through the grounds offers a chance to trace the footsteps of the Egawa family and their role in Japan's modernization. Exploring the collection of historical documents, weapons, armor, and paintings provides a unique opportunity to understand the social landscape of the time.
The area around the Egawa Family Residence is rich in historical atmosphere. It is located near the 'Nirayama Reverberatory Furnace,' a UNESCO World Heritage site. Visiting both sites together allows for a comprehensive understanding of the history of the late Edo and Meiji periods. The surrounding area is also perfect for combining historical exploration with nature walks through the beautiful landscapes of Izu.
