点评:I visited the Iwaya Cave in early March 2026 during a one-night trip to Enoshima, and it turned out to be the highlight of my visit to the island.
The caves were formed over thousands of years as waves eroded the coastal rock along geological faults. There are two caves: the First Cave, about 150 meters deep, and the much shorter Second Cave. In the First Cave, visitors explore the interior carrying candles, which creates a wonderfully atmospheric experience. Along the way there are religious objects and monuments, reflecting the cave’s long history as a place of devotion. Tradition holds that figures such as Kukai and Nichiren practiced here, and pilgrims have long visited the cave carrying candles to pray.
The Second Cave is lower and narrower in places, so visitors may need to bend over as they proceed. At the far end, a statue of Ryujin, the dragon god associated with the founding legend of Enoshima, appears in dramatic purple lighting. When visitors clap their hands, flashes of light simulate lightning—an entertaining and memorable finish to the exploration.
One practical point: from the torii gate at the northern entrance to the island, reaching the cave requires quite a long walk with many ups and downs, so visitors should allow plenty of time. I found the return walk rather exhausting. There is also a small boat service from near the torii gate to Chigogafuchi, which takes only about ten minutes, but the schedule is irregular and it may not be reliable if you are pressed for time.
For anyone visiting Enoshima, however, making the effort to reach the far end of the island is well worth it.
翻译:2026年3月初,我前往江之岛进行了一晚的短途旅行,期间参观了岩屋洞,没想到这竟成了我此行最大的亮点。
岩屋洞是数千年来海浪侵蚀地质断层沿岸岩石形成的。洞内有两个洞:第一洞深约150米,第二洞则短得多。在第一洞中,游客手持蜡烛探索洞内,营造出一种奇妙的氛围。沿途可见宗教物品和纪念碑,反映了岩屋洞作为宗教圣地的悠久历史。相传空海和日莲等法师曾在此修行,而朝圣者也一直手持蜡烛前来祈祷。
第二洞较低,部分区域也较为狭窄,因此游客可能需要弯腰才能通行。在洞的尽头,一座龙神像在紫色灯光的映衬下显得格外醒目,龙神是江之岛建岛传说中的神祇。当游客拍手时,会闪烁出模拟闪电的光芒——为探索之旅画上一个有趣而难忘的句号。
温馨提示:从岛屿北入口的鸟居到洞穴需要步行很长一段路,而且有很多上下坡,所以游客应该预留充足的时间。我发现回程走起来相当累人。鸟居附近也有小船前往千后渊,航程大约十分钟,但班次不固定,如果您时间紧迫,可能不太方便乘坐。
不过,对于任何到访江之岛的人来说,前往岛屿的尽头绝对值得。
