Mozu-Furuichi Kofun
Mozu-Furuichi Kofun Group: Mounded Tombs of Ancient Japan comprises 49 distinctive, often keyhole-shaped earthen burial mounds.
The tombs were made for kings and their associates and date from the peak of the Kofun period (4th-5th century). Moats surround the geometric terraced mounds. A rich selection of grave goods and clay figures that used to stand on top of the mounds have also been preserved.
Community Perspective: the keyhole shape is best seen from the air, and you can do so shortly after the departure from Kansai Airport westwards. Hubert also describes several tombs in the Mozu cluster that he visited at street level, GabLabCebu and Tsunami both visited Nintoku-tenno-ryo (a.k.a. Daisen Kofun) which seems to be one of the main ones. Philipp has visited 38 components divided among both clusters, while Els zooms in on the museum.

First, I’d like to thank Philipp for making the effort to cover the Furuichi cluster so I could cross that from my to-do-list. Even when limiting myself to the Mozu cluster, I found it a labour-intensive visit as I walked 8.2 km across 3 hours in the heat (still 33 degrees Celsius in late September). I did: Sakaihigashi Station – Sakai City Hall Observation Lobby – kofun in the north – hike towards Daisan Park along the westside of Nintoku-tenno-ryo – Sakai City Museum – small kofuns in the park - Itasuke kofun – ceremonial Gate to Nintoku-tenno-ryo – Mozu Station. A useful downloadable map with hiking routes along the points of interest can be found here.
I’d like to focus on what can be seen at the Sakai City Museum. The museum has a central location in the park and charges a small entrance fee (200 yen). You will be ushered directly into the film theatre, where an animated film with English subtitles explains their historical context, how the kofun were made, and how they looked like. The kofun were monumental platforms for burial ceremonies, made out of earth and dry stone walls (not tree-covered as nowadays) – the result looked a bit like Mesoamerican sites such as Monte Alban. The rulers of the time were trading with the Baekje in Korea and the Liu Song in China and were also influenced by their cultures. They also learned (from what is now Mongolia) that you could ride …

You can tick this site very easy, or you can go tryhard. The easy version would be to take the train from Osaka to Mikunigoaga station, cross the road and take a picture of Genemonyama Kofun. Done.
Me, on the other hand, I went tryhard. In honour of the legendary Iain Jackson, I panned to visit over 50% of the components, even though after seeing a few, there is little reward in seeing more.
Furiuchi cluster
I left my family in Osaka and first went to the Furiuchi cluster. From Osaka I took the train to Hajinosato station, started with the one north to the station and then walked all the way down the cluster, ending at Furiuchi station. I covered 19 components along the way. Way more than necessary, but at a certain point my competitive streak kicked in. There is really not much to see. The bigger ones have some kind of medieval water trench around the mound. Those bigger mounds are completely covered in forest. They are all not accessible, but I doubt there would be something to see besides trees. The smaller ones are naked mounds or with a few trees on it. Nabezuka Kofun just next to Hajinosato station can be climbed. The rest is fenced off. It felt weird to cover this cluster, as most mounds are entirely within the suburbs, between houses. Without any knowledge about the existence of these Kofun, I would have probably mistaken them for unused patches of land, …

Without doubt, you get the best impression of this WHS from an aerial view. Shortly after the departure from Kansai Airport westwards you have a perfect view of the Mozu Konfun complex. It is strange to see these huge tombs like green islands in the middle of a sea of modern buildings. One inevitably wonders what this densly populated area may have looked like in the 5th century when the largest of these kofuns were built. And what remains of this ancient culture might still be hidden underground. However, the builders of these tombs have left no written records, no remains of palaces or fortifications have been preserved. Only the kofuns and the artifacts that were found in there.
Visiting this WHS at street level is odd and unsatisfying. What you can see are tree-covered mounds and the moats that surround the larger kofuns. From this perspective, their keyhole shape can only be guessed. The kofun of Emperor Nintoku is the largest of the inscribed tombs. However, there are also doubts as to whether it is really Nintoku’s tomb. Certainly an important person was buried there, the kofun has a total length of about 800 meters and is one of the three largest tombs worldwide. You can walk around on a circular path, but there is not much to see apart from the closed entrance gate and the outermost of the three moats.
I liked the medium-sized kofuns better, where you have an unobstructed view to the actual burial …

WHS#80
After a failed attempt to visit Antequera in early 2017, I finally succeeded in visiting a WHS inscribed less than a year before on my December 2019 trip to Kansai and Hiroshima. The kofungun at Mozu in Sakai are now the closest WHS to Osaka, and it's from there that I visited Nintoku-tenno-ryo. I used the Nankai Line to Mikunigaoka Station, which is basically at the tip of the great tomb, and walked the whole length of it to the front. Mozu Station is actually closer to the front, and you can access it on the JR Hanwa Line. On the way, I passed a few small circular mounds, including one that seemed to be accessible from the adjacent garage. Otherwise, the scenery was quite uniform throughout the walk, just a small canal-like moat on one side and modern houses on the other. The trees on the mounds look lovely in autumn colors, though. Upon reaching the front of the famous kofun, I was greeted with the view that everyone who comes to this little-known site gets. Crossing the bridge reveals another moat layer behind the first, and in the distance, a Torii gate seems to serve as the spiritual entrance to the tomb. While the mound is huge, probably even greater in volume than than the Pyramids of Giza, it sure doesn't have the same effect.
The mound looks like a forest, and that's mostly what it is. It's not significantly taller than its surroundings, and …

In 2014 I visited the centerpiece of this nomination, the Daisen Kofun, which is considered to be the grave of Emperor Nintoku and is the single largest grave in the world by area.
It is so large that the best way to view it is perhaps to take off or land at the Kansai (Osaka) International Airport.
The photo shows the Shinto Torii Gate in the middle, behind which lies the widest of the three moats that surround the all important keyhole-shaped grave.
I believe it'll be surprising if this site gets a go at getting on the WH list, simply because, no matter what the nomination dossier says, nobody is certain that the Daisen Kofun is really the grave for the Emperor. This absurdity comes from the fact that the belief that the grave belongs to an Emperor means it is managed by the Imperial Household Agency, an ultra conservative entity that wouldn't allow anyone to visit such a holy site, let alone to dig it, resulting in the uncertainty. (Remember that the Japanese Imperial Family is considered to be the descendants of Amaterasu, the Sun Goddess, in the Japanese mythology.) I was told by a man who managed this property on site that the Ministry of Culture, which takes care of the World Cultural Heritage in Japan, had been unsuccessfully battling it out with the Imperial Household Agency, which takes care of the living deity!
But this nomination is not just about the Daisen …
