Natural beauty that will leave you in awe. One of Japan's largest limestone caves.

The total length of the cave is the largest in Japan, exceeding 10km. On the approximately 1km tourist course, you can see numerous natural formations. In particular, the "Hyakumadara" that resembles terraced rice fields is worth seeing.

Highlights

Point 1

Overwhelmed by the Stalactites on the Terraced Rice Fields

Probably the most famous spot in Akiyoshido, many people may have seen it in photos. After walking for a while inside the cave, you'll come across the "Hyakumadara" (Hundred Plateaus). You'll be overwhelmed by the sight of stalactites of various sizes, resembling terraced rice fields. Some travelers may even think it looks like Pamukkale in Turkey! Although it's called "Hyakumadara" (Hundred Plateaus), in reality, there are more than 500 connected stalactites, so it might be interesting to count them once.

Point 2

Comparing Height with a Golden Pillar that Looks Like Lace

The Golden Pillar inside Akiyoshido Cave is an impressive stone pillar that is 15 meters tall and 4 meters wide. It's said to have been formed over a long period of time by underground water flowing from the ceiling and along the walls, allowing visitors to truly appreciate the power of nature. The center pillar is surrounded by many thin pillars that overlap, creating a delicate lace-like appearance. Comparing your height to the Golden Pillar allows you to better appreciate its size!

Point 3

Discover Mt. Fuji inside a Cave

After passing through the hundred-plateau, you'll enter a spacious area where the "Cave Mt. Fuji" stands out like the real Mt. Fuji. While Cave Mt. Fuji can be found in other limestone caves, the one inside Akiyoshido Cave is overwhelmingly large and impressive. It's said that the water dripping from the ceiling created this huge mountain, and it's amazing to think that such a large structure was formed over a long period of time.

Point 4

Be Amazed by an Abundance of Stalactites

At the entrance to the Senjojiki area, the largest area inside the cave, there is a group of stalactites called "Kasadori". It is said to be named after the way old umbrella shops used to hang their umbrellas from the ceiling. The sight of many icicles hanging from the ceiling is truly fascinating and captivating.

Point 5

Viewing the "Jellyfish Waterfall Climb"

On the way to the final cave, there is a spot called the "Jellyfish Waterfall Climb," which looks like jellyfish climbing up a waterfall. While jellyfish that live in seawater don't actually climb waterfalls, one can't help but imagine what it would look like if they did. It seems that the underground water seeping from the rock wall has created this unique feature, which has been named the "Waterfall-shaped Limestone Deposits."

Point 6

Comparing the "Hyakumaidara" and "Chimachida" Plates

In addition to the "Hyakumaidara" plates, there are also formations called "Chimachida" in the Akiyoshido Cave that resemble the terraced rice paddies of the region. These formations spread out in the space beyond the Mt. Fuji area of the cave and have softer curves than the Hyakumaidara plates. It's a truly fantastic sight to behold. While they may resemble the rural terraced rice paddies more than the Hyakumaidara plates, how do you feel about them? Why not compare the two and find out for yourself?

Point 7

Challenge Yourself on the "Adventure Course"

To fully enjoy Akiyoshido Cave, why not try the "Adventure Course" instead of just following the tourist route? Starting from the left side of the "Aotenjo" near the main entrance of the cave, this course climbs the rocky surface and follows an unmarked path, relying on the light of your flashlight. It's a 100-meter, 10-15 minute course that will stimulate your sense of adventure with activities such as climbing ladders and crawling through holes. Enjoy the thrill of the adventure!

Required time

Recommended to Allow About an Hour and a Half

The tourist course at Akiyoshido Cave is about 1 kilometer long, and takes about 60 minutes as a guideline, but it takes about 90 minutes to go back and forth. You can enjoy walking while crawling through gaps and climbing ladders, not just walking. By the way, the ground is slippery and wet, so it is recommended to visit in shoes that are not slippery, such as sneakers.

Access

About 30 Minutes by Car from JR Shinyamaguchi Station

It's convenient to access Akiyoshido by car. It takes about 30 minutes by car from JR Shinyamaguchi Station, where the Nozomi Shinkansen stops, and about 45 minutes by car from Yamaguchi Ube Airport if you come by plane. There is also a municipal parking lot in front of Akiyoshido, so you can rest assured. If you can't use a car, it will take a little longer, but there are buses from JR Shinyamaguchi Station and JR Yamaguchi Station, so use them.

Fee

Adults can enter for 1,300 yen!

To enter Akiyoshido Cave, adults and high school students need to pay 1,300 yen, middle school students need to pay 1,050 yen, and elementary school students need to pay 700 yen. There is also a group discount for 20 people or more, so it would be lucky if you can apply it when going with a large group. To enjoy Akiyoshido Cave even more, there is a place called the "Adventure Course," which you can enter for an additional 300 yen. Since you've come all this way, why not try it out?

想像以上に素晴らしかったです。まず、洞窟の広さに圧倒されました。入口から入るとひんやりとした空気が広がり、すぐに非日常的な空間に引き込まれます。特に「百枚皿」や「黄金柱」といった鍾乳石の造形は本当に壮観で、自然が生み出す芸術に感動しました。道は整備されていて歩きやすく、途中にはライトアップも施されているので、幻想的な雰囲気を楽しむことができました。観光客が多い時期でも、洞内は広々としているので、人混みが気になりませんでした。友人と一緒に行ったのですが、探検気分が味わえるので、写真を撮ったり、珍しい鍾乳石を見つけたりと、終始盛り上がりました。鍾乳洞は自然が長い年月をかけて作り上げた場所なので、その歴史や神秘を感じられる点もよかったです。秋芳洞はアクセスも比較的良好で、駐車場も整備されているので、ドライブがてら訪れるのにもぴったりです。自然好きの人や、少し変わった観光地を探している人には本当におすすめです。

秋吉台国定公園の地下に開口する、国内第二位の大鍾乳洞。周辺駐車場は、1日料金で500円、ですがあえて、手前にある「カルスト」さんがおすすめ。 1日100円です。。笑笑洞内は、かなりヒンヤリとしているので夏は気持ち良いです。心なしか、全身しっとりと保湿された感があります。往復でだいたい1時間ほどです。洞内の道は舗装されていますが、なるべく歩きやすい靴がオススメ。また別コースで少しハードな「冒険コース」？（別途300円要）なるものがあり、こちらはクライミングに自信のある方は良いかと思います。洞内途中には、秋吉台展望台に繋がるエレベーター🛗があるので、行き来できます。子どもさんにも、もちょっとした冒険気分が味わえる、鍾乳洞です。鍾乳洞まで続く、露店で食べた手作りコロッケがチープな味で美味しい😋かったです。【営業時間】 8:30～17:30 閉洞18:30 ※3月～11月通常期 8:30～16:30 閉洞17:30 ※12月～2月閑散期 ※黒谷入口・エレベーター入口からの入洞は16:30まで年中無休（年末年始も通常通り営業）入洞料金大人　（高校生〜）1,300円中学生　　　　　1,050円小学生　　　　　　700円

国内屈指の鍾乳洞。駐車場は近くから離れた所まで，500円で有ります。鍾乳洞の中は少し湿度ありますが、ヒンヤリしていますので、一枚多めに上着持参で。内部は滑りやすいのでスニーカーなどが無難です。途中からエスカレーターで地上に出ることも出来ますが，帰りはバスになります。終点まで行って引き返すのが良いと思います。ライトアップは少し暗いので立体的に観察し難い感じです。でも海外の様に（ベトナムなど）ピンクや黄色のライトを付けるのはやめた方がいいです。スロべミアのボストイナ鍾乳洞などもっと明るくて，観光しやすかったです。
