Sakai City: Nintoku Mausoleum, City of Blades, and World Heritage Burial Mounds

World Heritage Burial Mounds

The Mozu-Furuichi Kofun Group, inscribed as a UNESCO World Cultural Heritage site in 2019, is a cluster of giant burial mounds built around the 4th to 5th centuries. Among them, Nintoku Mausoleum (Daisen Kofun) is Japan's largest keyhole-shaped mound at about 486 meters in length. Its grand scale is clear from above, revealing the distinctive keyhole form.

Nintoku Mausoleum

From the ground the Nintoku Mausoleum looks like a forest, but its scale can be felt from the worship area surrounding it. Built in the mid-5th century and encircled by double and triple moats, the mound is thought to have taken many years to construct. From the adjoining Sakai City Museum and nearby viewing spots, the spread of the mound group can be seen at a glance, and the green circuit paths are popular as walking courses.

Sen no Rikyu and the Blade Tradition

Sakai is also known as the birthplace of Sen no Rikyu, the master who perfected the tea ceremony. The Sakai Rishonomori facility offers an accessible way to learn about tea culture and Sakai's history. Sakai forged blades are renowned as top-grade knives loved by chefs, and facilities where you can observe or try the artisans' handwork are popular.

Access and Basic Information

• Nintoku Mausoleum is a short walk from Mozu Station on the JR Hanwa Line, close to the Sakai City Museum and Daisen Park.
• Mikunigaoka Station (JR Hanwa Line and Nankai Koya Line) and Sakaihigashi Station (Nankai Koya Line) are also convenient bases for touring the city.
• It is about 15 to 20 minutes by train from central Osaka (Namba), with good access from Kansai International Airport as well.
• The interior of the Nintoku Mausoleum mound cannot be entered, and viewing is basically from the worship area.

Practical Travel Notes

• The mound's full form is hard to grasp from the ground, so picturing the overall shape at the Sakai City Museum or nearby viewing facilities before walking helps you sense its scale.
• Spring and autumn are especially pleasant for touring the mounds and walking the town. The circuit paths are long, so comfortable walking shoes are recommended.
• Some Sakai blade workshops and knife shops offer knife-sharpening experiences or purchases. Checking opening days and whether reservations are needed in advance makes for a smoother visit.
• Sakai Rishonomori offers a matcha tea-serving experience, recommended for those wanting to touch tea ceremony culture.

A Word of Advice

Being only about 20 minutes by train from central Osaka, Sakai is ideal for a half-day to full-day trip. Touring the mound group and Sakai City Museum in the morning, then visiting Sakai Rishonomori and a blade workshop in the afternoon, makes for a distinctly Sakai journey that combines ancient history with artisan craft.
