Luminous Moss, Military Factory and 100 Caves of Yoshimi | YOSHIMI

100 caves of yoshimi (5)One of our first adventures this year (2015), brought  us to the 100 caves of Yoshimi, a country designated historical site. The caves are tombs and there are actually 219 of them.  They are the largest cluster of tombs of this type in the whole of Japan and have been nicknamed the Japanese Cappadocia. A description I must admit I find hyperbolic. It was our first time to visit the caves and an attraction of that type. I wasn’t sure how much the kids would enjoy it. Much to my delight, they were really eager to explore the terrain and the facilities on site.

Sakura on Moss

Although Japan’s Cappadocia it is not, the area is worth a visit for its unusual landscape and the history.  The tombs are a 1400 hundred year old burial mound. They are also home to an underground military factory site, built toward the end of World War II. Another point of interest of the site is that is home to a national natural treasure; hikarigogake. Hikarigogake is luminous moss, and a type of moss that is very precious in the region of Kanto (area around Tokyo) as one of the plants that  grows naturally.  It shines best from April to October and the darker it is the easier it is to see, so actually a rainy day or late afternoon might be the best time to witness this natural phenomenon.

World War II Bunkers
Underground Military Factory Site

The underground military factory site is on the ground floor in tunnels carved into the mountain. The kids thrilled in running around, and pretending to be super heroes fighting evil. (Yes, I know, the irony!) These huge caves were dug at the end of World War II for an underground airplane engine factory that never really realised. It had begun manufacturing airplane engine parts before the factory was complete, around July 1945, but when the war ended so did manufacturing and the factory was never completed. The biggest shame in it is that more than 10 of the designated national historic site’s  “hyakuana” were lost in the construction.

100 Caves of Yoshimi Blog (2)The caves (/tombs) themselves were only excavated about 60 years before World War II by Tsuboi Shogoro. Thankfully, they have been pretty well preserved since the end of World War II. My kids really enjoy climbing the dozens of steps made to give better viewing of, and in some cases access to, the caves.   The stairs are quite steep and there is a lot of them so I would advise you leave your buggy / stroller in the car. Or park it by one of the buildings in the courtyard as you can wheel a buggy through the bunkers. The accessible caves have low entrances and while some of them are difficult for adults to enter they are no problem for kids. My kids quite like playing house in them!

Traditional Toys at 100 Caves

There are a couple of restaurants and shops within the site and there is also a museum (officially Reserve Cultural Property Center) and in the reception building they have an event space. The Reserve Cultural Property Center has some excavated items on display from the Jomon Period, but it is best known for its comma-shaped bead making class.
My kids like to play with the toys that they set out in this event space at the entrance.  At New Years they have traditional New Year toys set out and during the year they have different types of toys for kids to play with.

Colouring pages at 100 Caves

They always have some toys and colouring pages and markers available for young children to play with. We have been to some of their festivals were they typically offer some sort of free craft. On special occasions they also put out some Jomon period clothes (cloth robe essentially) for people to try on and take a photo.

Beware of Susumebachi sign

One thing to note:  it is not the safest of places to bring more than 2 small children per adult.  On our very first visit it was just me with my 4 and my youngest was still a newborn. I had her in a baby carrier and my 2 year old held my hand, but my then 3 year old and 5 year old ran ahead to climb the stairs to the top of the hill. They were okay, but an accident could easily happen as the hill is very steep and there are limited guard rails and the ones that do exist my kids would slip through! Also, in the summer and autumn they have a problem with killer hornets.  All that said, it is still a place worth visiting!
