What makes it 74% Couple-Friendly: Exploring the eerie lava tunnel together plus forest walk feels romantic and cheap, yet cramped passages limit side-by-side walking and the visit ends in about 15 minutes.
Why 1-2 hours visit duration is ideal for couple trip: Includes a 15 min cave walk, 20 min forest trail, and time for photos and snacks
Lava Tube Exploration:
Walk the 153 m tunnel to see ice pillars and lava stalactites.
Tip: Bring a warm jacket and sturdy shoes for the 0–4 °C interior.
Combo Ticket with Wind Cave:
Buy a joint ticket for Narusawa Ice Cave and Fugaku Wind Cave.
Tip: Start at Narusawa first to beat the midday crowd.
Forest Trail Stroll:
Hike the 15–20 min Tokai Nature Trail between the two caves.
Tip: Pause to photograph tree-root formations along the path.
Local Sweets at Cave Shop:
Try a Shingen Mochi or blueberry parfait after the tour.
Tip: Enjoy your dessert on the outdoor benches by the entrance.

Quick 10 min experience through a cave with a nicely set out path and stairs, and two shrines. The ceiling in some parts are really low so you'd have to crouch / bend to navigate through, but it's not too difficult. It's cold as well so do layer up before heading in. We didn't see too much ice, they may have melted over the years?

Narusawa Ice Cave is another place I visited during my trip to Mt. Fuji. Visiting this ice cave offers a great opportunity for physical activity and exercise. I'm glad I can handle it. The Narusawa Ice Cave is not particularly impressive. However, it's fun if you have a whole group of friends who can go together.

It can be slippery and tight in spots, even a section to almost cr...

Located in the Aokigahara Forest at the northwestern foot of Mt. Fuji, Narusawa Ice Cave is a small lava tube formed about 1,150 years ago during one of Fuji’s eruptions. The temperature inside remains around 0–3°C throughout the year, allowing impressive ice formations to persist even in summer. The walking path is short — about 150 meters — leading down a narrow, slippery tunnel with solidified...

Cheap but cheerful cave experience amongst beautiful naturescape. Visit during winter to see ice pillars. We visited in autumn & signs pre-warned ice pillars had melted, so we knew what to expect. Still went for the experience! Steep but short climb down 21m. Cold, so prepare accordingly. Watch your head for low hanging rocks. A short section where we had to pretty much crawl through - a unique ex...
Visit between March and August to see the largest icicles inside the cave.
