Iwamura Town and Iwamura Castle Ruins
Iwamura Town is also designated as an Important Preservation District for Groups of Historic Buildings. During Edo Period, this town was the center of commerce of the Iwamura Castle Town but this town was off the main trafic route, so it has retained the traditional setting since then. At the top of the Mt. Shiroyama, ruins of Iwamura Castle remains. This castle is known as one of the three major castles standing on high elevation area because its main structure was located at 717m above sea level. Japanese Sake brand with "Female Lord of the Castle" is also popular among tourists to this town.

Hina Dolls Festival in the Iwamura castle town [Beginning March through Beginning April]
Hina Dolls are on display at around 100 places, either under the eaves on the showcasing stages, entrances to the houses, and/or display rooms, in row of historical houses of designated important traditional structures in Iwamura Town. This event first started with those hina dolls long kept in storage behind in the house over the years, then they were brought in front and was on display to the local residents and the tourists. As this event turned out a success, this has become the official event of the town. Now at Kimura's Residence and at Tosa-ya, both of which are the town-designated historical structures, the dolls are on display to entertain the tourists. Among those exhibits, there are clay dolls and hanging scrolls depicting hina dolls, too.
