Packing for Aokigahara requires preparing for both a dense forest and cold underground caves. Even on a hot summer day, you need specific gear to safely explore the uneven volcanic floor and the icy caverns.
What kind of shoes do I need for Aokigahara?
You need sturdy hiking shoes with non-slip soles.
The forest grew over hardened lava from Mount Fuji's 864 CE eruption. The trails are uneven, and stepping off the path exposes you to deep holes and treacherous terrain. Thick-soled hiking boots protect your feet from jagged basalt rock.
How cold are the lava caves?
The underground lava tubes stay near freezing year-round, averaging around 3 degrees Celsius.
You need a warm jacket or thick sweater to enter the Narusawa Ice Cave and Fugaku Wind Cave. Ice pillars remain frozen inside the Narusawa Ice Cave even during summer. A rain jacket or poncho is also useful for sudden weather shifts near Mount Fuji.
Do I need a map and compass?
Yes, you should carry a physical map and a magnetic compass.
Cellular service and GPS signals often drop inside the dense forest. A physical map ensures you stay on the marked Tokai Nature Trail. A magnetic compass helps you orient yourself if you lose your way, as the trails look similar in all directions.
What else should I pack in my daybag?
Bring a power bank to keep your phone charged and a small first-aid kit.
The porous volcanic rock is sharp. A first-aid kit is helpful for minor scrapes if you trip on the lava roots. Carry your phone for emergencies, but rely on your power bank to keep the battery full when searching for a signal.
Can I buy food and drinks in the forest?
No, facilities are only located at the main cave entrances.
Bring a water bottle and snacks in your backpack. You cannot buy supplies once you are on the hiking trails. Remember that Aokigahara is a Special Protected Zone, so you must carry all trash out with you.
Do I need special equipment for the caves?
The main walking routes require no special gear, but low ceilings require caution.
The Narusawa Ice Cave descends 21 meters below ground, and the ceiling is very low in places. You will need to crouch or bend double. If you book a specialized cave tour, the operator provides exploration equipment like a helmet, overalls, gloves, and a headlight.
Questions travellers ask
Can I wear sneakers to Aokigahara Forest?
Basic sneakers are not recommended. You need sturdy hiking shoes with non-slip soles to safely walk over the jagged, uneven volcanic rock on the trails.
What should I wear to Aokigahara in summer?
Wear light, breathable clothing for the forest trails, but pack a warm jacket in your bag. The Fugaku Wind Cave and Narusawa Ice Cave stay near freezing all year.
Are there restrooms along the trails?
Facilities are only available near the main cave entrances, such as the Saiko Bat Cave or Narusawa Ice Cave. Use the restrooms before starting your walk.
