Daisen Park is a large 38.5 hectares public green area located in Sakai, in the southern suburb of Osaka. Stretching between the huge Kofun burial mounds of emperors Nintoku and Richu, the park also shelters 2 museums, 2 tea houses, a Japanese garden and about 1,000 cherry trees, that make it the ideal place to celebrate hanami in spring.

Inaugurated in 1947, the iconic park of Sakai City extends between the 47 ancient graves and tumuli of Mozu Kofungun group, enlisted in the UNESCO World Heritage in 2019. It borders the famous Daisen-ryo Kofun in particular, which is emperor Nintoku’s immense mausoleum shaped as a keyhole and one of the biggest tombs in the world.

Daisen Park’s 38,5 hectares are home to several buildings and facilities, including :

  • Japanese garden and a botanical center;
  • Two tea houses;
  • Two municipal museums;
  • A library; and,
  • Children playgrounds.

Many flowers and tree species also decorate the alleys and underline the passing of the seasons, such as the sakura 🌸 in spring, irises in summer and maple trees in autumn 🍁. Sakai’s inhabitants enjoy this neighborhood park all year long. As for sightseers, they get to enjoy a walk complemented by historical and cultural visits.

Of an easy access by train 🚅 from the south of Osaka, the site located in an urban suburb is consequently crossed by electric poles and wires, and nature is unfortunately absent from the surroundings. Moreover, we recommend renting a bicycle to tour the park and the area.

Japanese garden and sakura in the heart of the city

Nearly 1,000 Japanese cherry trees blossom at the end of March to early April and announce the beginning of spring and the return of warmer temperatures. At this time of the year, Daisen Park is full of the neighborhood’s families and friends who gather on tarps to celebrate hanami.

Rather large, it includes a main pond with a traditional pavilion and several Japanese bridges, as well as other smaller spaces such as an aquatic garden for irises.

The Obaian and Shinan tea houses complete the walk and offer a welcome rest with a matcha tea and its confectioneries. The traditional building of the Shinan house dates back to 1929 and was designed by Japanese architect Ogi Rodo. First constructed in Tokyo’s Shiba Park, the building was moved to Sakai in 1980.

The grave of emperor Nintoku, called Kofun Daisen-ryo dates back to the 5th century and is the most monumental of all : it is 820 meters long, 654 meters large and is completely covered by the vegetation. It is also surrounded by moats and its entrance, marked by a graveled plaza and a torii ⛩️ gate, is easy to be overlooked when walking on the sidewalk. From the ground, the burial mound indeed looks like a little forest, and it is not open to the visit. Its large size and keyhole shape are better comprehended seen from above.

For this purpose, you can first go to Sakai City Hall Observatory for a first look from an elevated place. Then, you can flight ✈️ in a tourist helicopter 🚁, for example, to enjoy an aerial view on the largest tumuli of Mozu, such as:

  • Kamiishizu Misanzai Kofun (tomb of emperor Richu);
  • Nisanzai Kofun;
  • Gobyoyama Kofun; and,
  • Itasuke Kofun.

If you want to discover the cultural heritage in relation to these great tombs, you should go to Sakai City Museum in Daisen Park. Part of the exhibits is dedicated to the Kofun, with:

  • A reconstitution to understand the layered architecture of the mounds,
  • A collection of funeral clay figures, called haniwa that have been excavated, and,
  • Videos providing a virtual visit.

These tombs were never fully explored nor thoroughly maintained in order to preserve their holy character.
