Shibayama Kofun Haniwa Museum, Archaeological museum in Shibayama, Japan.

The Shibayama Kofun Haniwa Museum is a municipal museum in Shibayama, Chiba Prefecture, opened on 1 May 1988 in Shibayama Park. Its three exhibition rooms display haniwa clay figures excavated from surrounding kofun, including a reconstruction of the funeral procession from the Tonozuka and Himezuka tombs of the Shibayama kofun group.

The museum opened on 1 May 1988 in Shibayama Park to present the Kofun period from a modern viewpoint. The burial mounds around Shibayama were built between the 5th and 8th centuries, and the displays draw on finds from the Ogawadai, Kabuki and Yamada-Takabuma groups. The Shibayama mounds, including Tonozuka and Himezuka, yielded funeral haniwa processions shown in reconstruction.

The exhibits reveal how ancient people honored their dead through clay figures depicting priests, soldiers, and animals in ceremonial arrangements. Visitors can see how these statues were positioned in processions to accompany the deceased into the afterlife.

The location is easily accessible in the Shibayama area and welcomes visitors during regular operating hours on most days. Signage is provided in both Japanese and English to help navigate the exhibition spaces and understand the displays.

The museum opened on 1 May 1988 inside Shibayama Park, built around the idea of presenting the Kofun period clearly and enjoyably for primary schoolchildren. It also supports the Shibayama Haniwa Festival, held every November, and takes part in the Narita Welcome Card programme for international visitors.
