Fujido Cave

Located in the mountains of Ueno Village in Gunma, Fujido is one of the largest limestone caves in the Kanto region, stretching roughly 2.2 kilometers in total length. Walking through its cool passages, you can admire underground formations shaped by nature over countless years. Local legend says villagers discovered a small opening here about 1,200 years ago, and a monk later used the cave for spiritual training, which is why it has long been cherished as a place of purification. Cradled by deep mountains and clear air, it is a perfect spot to step away from daily life and quietly turn inward.

Highlights

• A mysterious underground space lined with stalactites and stalagmites grown over ages
• A sense of adventure from the long spiral staircase that climbs a vertical shaft beyond the entrance tunnel
• Cave formations dramatically lit for a fantastical effect
• Many points of interest within the cave named after Buddhist themes

Enjoying the Seasons

The temperature inside stays around 11 degrees Celsius all year, so it feels refreshingly cool in summer and gently warm in winter. It is perfect both as a summer retreat from the heat and as a quiet walk in the colder months. The surrounding Ueno Village is beautiful with fresh greenery and autumn foliage, and pairing the cave with the village gorges and suspension bridges makes for a fine outing. Every season shows a different face.

Access and Basic Information

• Location: Ueno Village, Tano District, Gunma Prefecture (within Kawawa Nature Park)
• About one hour by car from the Shimonita Interchange on the Joshin-etsu Expressway
• Public transport is limited, so traveling by car is recommended
• Reception hours, admission, and winter closures vary by season, so check in advance with Ueno Village tourist information
• Allow roughly 40 minutes for the tour route

Practical Travel Notes

• To reach the cave you first walk through an artificial tunnel of about 120 meters, then climb a spiral staircase up a vertical shaft roughly 40 meters high. The continuous stairs mean anyone unsure of their stamina should keep a comfortable pace.
• The cave is lit but dim, and the floor is always damp and slippery, so well worn shoes with good grip, such as sneakers, are safest.
• At around 11 degrees year round it feels chilly, so a light jacket is welcome even in summer.
• Mobile phone signal can be weak in these mountains. Sorting out information at nearby facilities such as Michi-no-Eki Ueno before you set off makes the trip smoother.
• The nearby Ueno Sky Bridge, a suspension bridge linked with Fujido, makes a good pairing for a full day out.

A Quick Tip

Parts of the cave are dim and slippery, so shoes with good grip will help you feel secure. Since the underground is chilly, bringing an extra layer even in summer will keep you comfortable. As the mountain drive is long, fill up on fuel early.
