According to the Nihon Shoki, the 31st Emperor Yomei was buried in the Ikegami Tomb in Iware, but later, in the first year of the reign of Emperor Suiko (593), it is recorded that he was reburied in the Isonaga Tomb in Kawachi. The tomb of Emperor Yomei is a square burial mound measuring 65 meters east to west, 60 meters north to south, and 10 meters high, and is surrounded by a dry moat 7 meters wide. Including the outer bank of this moat, the tomb is enormous, measuring 100 meters on each side. It is noteworthy that the size and shape of the burial mound are very similar to the Ishibutai Tomb, believed to be the tomb of Soga no Umako.

The 33rd Empress Suiko, Japan's first female emperor, appointed Prince Shotoku as regent, and actively absorbed advanced political systems, culture, and art through negotiations with the Sui Dynasty on the continent, leading to the flourishing of Asuka culture, which was centered on political reform and Buddhist culture. Upon her death in the 36th year of the reign of Suiko (628), she was buried in the tomb of Prince Takeda in Yamato, and later reburied in the Isonaga mausoleum in Kawachi.

Emperor Kotoku, the 36th emperor, ascended to the throne after the Taika Reforms. He appointed Soga no Kurayamada Ishikawamaro, who had contributed greatly to the reforms, and promoted reform politics. However, the emperor fell out with Prince Nakano Oe and others, and died alone at Naniwa Palace in 654, the fifth year of the Hakuchi era, and was buried at Isonaga no Miya in Osaka. Located along the Takeuchi Kaido road, the tomb is a small circular burial mound with a diameter of approximately 30 meters, also known as the "Uguisu no Mausoleum." It is said that a mirror known as the "Kaiju Budou Kagami" (Sea Beast and Grape Mirror) was once excavated from a secondary tomb.

The temple is known as the place where Saigyo, a poet from the late Heian period, ended his life during the cherry blossom season, as he wrote in his poem, "I wish to die in spring beneath the flowers, around the time of the full moon in Kisaragi."

The temple is home to the 25th sutra mound of the Katsuragi Shugendo, which has been designated a Japan Heritage Site, and is also known as "Kokaji Temple," and is worthy of its name, as the temple is decorated with a 110-year-old weeping cherry tree, as well as sasanquas, camellias, and camellias that change color throughout the seasons. In this tranquil atmosphere, you can try out activities such as copying sutras and zazen meditation.

This Western-style leisure spot opened in 1989 with the concept of creating a heart-to-heart connection between people, nature, and animals. Many animals live here, including a corner where you can try horseback riding, a grazing area where you can interact with sheep, goats, ponies, mini pigs, and ducks, and a corner where you can interact with small animals like rabbits. There are plenty of activities that children will enjoy, such as fishing and cow milking. The park also has barbecues, natural hot springs, and log cabins and cottages where you can stay overnight, making it a fun place for the whole family to spend the day.

The name "Iwahashiyama" comes from a legend that En no Gyoja once commanded Japanese gods, including Hitokotonushi no Kami, who is enshrined in present-day Gose City, Nara Prefecture, to build a rock bridge to Mount Kinpu in the Yoshino region of Nara Prefecture. A rock called "Kume no Iwahashi" near the summit is said to be a remnant of this bridge. The mountainside is also dotted with megaliths and unusual rocks, such as the "Nabekamaishi," "Hokotateishi," and "Tainai Kuguri," allowing visitors to explore these megaliths, evoking the romance of ancient times. In 2020, the Shugendo (Katsuragi Shugendo) path, which stretches from Wakayama Prefecture to Nara Prefecture, where En no Gyoja first trained, was designated a Japan Heritage Site.

This gourd-shaped twin-circular tomb is rare nationwide, and is believed to have been constructed in the late Kofun period (late 6th century to early 7th century), when keyhole-shaped tombs were on the decline. With a mound length of 85.8m and a total length including the surrounding moat of 102m, it is the largest twin-circular tomb in Japan and is a nationally designated historic site. Within the stone chamber on the northern hill is a horizontal-type stone chamber, where two house-shaped stone coffins were placed, and grave goods were excavated. A stone chamber was also confirmed to exist on the southern hill, but as it has not been investigated, its contents are unknown. It was designated a national historic site in 1991, and is maintained and preserved as a park, popular as a place to relax and learn about history.

Osaka Prefectural Sayamaike Museum is an outdoor museum that emphasizes the integrated use of the historic Sayamaike Pond, Japan's oldest dam-type reservoir.Operated in collaboration with Osaka Prefecture, Osaka Sayama City, and the Sayamaike Festival Executive Committee, the museum is open to the local community and aims to create new value and appeal for Sayamaike Pond.

We strive to collect all materials and information related to land development history from an East Asian perspective, and we will publicize and disseminate the results through permanent and special exhibitions. We also aim to become a learning and research center for land development history.
