Quick Answer
Seeing the Northern Lights at Mount Fuji is possible only during a very rare, extreme solar storm. A big one on May 10–11, 2024 made faint aurora visible in parts of Japan, but that was an exception. Plan for stargazing and lake reflections instead, and check official space-weather pages on your date.
TL;DR
- Aurora is a long shot. Japan is far south of the normal aurora zone. Only an extreme Kp event makes it possible.
- Aim for the sure win. Go for stargazing and mirror-calm lake reflections, especially on moonless nights in late autumn and winter.
- Check the sky like a pro. Use NOAA SWPC for the Kp index and Aurora Viewline, and NICT for Japan’s current space-weather status.
- Base yourself smartly. Kawaguchiko is easy and walkable; Yamanakako has big-sky horizons.
- Getting there is simple. From Shinjuku, take JR FUJI EXCURSION (direct), JR → Ōtsuki → Fujikyū Railway, or a highway bus from Busta Shinjuku.
- Be a good night guest. Follow Fuji-Hakone-Izu National Park rules, park legally, keep lights dim and voices low.
- About 2024’s aurora: It happened during a G5 storm on May 10–11, 2024—a rare outlier, not something to count on.

USD shown at ≈ 1 USD = ¥{RATE}; check live rates.
| Day | Area | Highlights | Transit time (from Shinjuku) | Booking notes |
|---|---|---|---|---|
| Day 1 (afternoon → night) | Kawaguchiko North Shore / Ōishi Park | Sunset color on Fuji; blue-hour mirror reflections; stars if the moon cooperates | JR FUJI EXCURSION ~1h50–1h55 (direct) or JR→Ōtsuki→Fujikyū ~2h; highway bus ~1h45–2h | JR East: FUJI EXCURSION is all-reserved (timetable valid Mar 15, 2025 and after). Busta Shinjuku: check the live departures board. |
| Night window | Tenjōzan Panoramic Ropeway (seasonal evenings) | Wide view over the lake at blue hour | Local bus/taxi; short walk | Confirm the day’s last ropeway run; bring a headlamp for paths. |
| Day 2 (pre-dawn) | Motosuko or Shōjiko | Darker skies; long-exposure shots | 25–45 min by taxi/car from Kawaguchiko | Check National Park/DMO notices for winter roads and parking. |
| Day 2 (morning) | Visitor center + onsen | Warm up; learn about Fuji; head back to Tokyo | Reverse route via JR or bus | Reconfirm your return—weekend seats can fill. |
When to go
- Crisp air: Late November–February often brings the clearest nights.
- Moon timing: Aim for new moon ±3–4 days for more stars and darker skies.
- Aurora reality check: Only try if the Kp index is extremely high the same day. Otherwise, enjoy the stars.
Where to stay
- Kawaguchiko (Lake Kawaguchi): Walkable, lots of food options, frequent buses, lockers by the station—great for first timers.
- Yamanakako: Big open views and fewer lights; nice for sky-heavy photos.
- Motosuko/Shōjiko: Dark and quiet; best with a car or taxi and a solid plan for safe, legal parking.
Getting around (and paying for rides)
- Trains:
- JR FUJI EXCURSION runs direct between Shinjuku and Kawaguchiko (all seats reserved; see JR East’s timetable valid from Mar 15, 2025).
- Or take a JR Limited Express (Azusa/Kaiji) to Ōtsuki, then Fujikyū Railway to Kawaguchiko.
- Buses: Busta Shinjuku has frequent highway buses to Kawaguchiko and Fuji-Q Highland. The terminal’s English live board shows gates and on-time status.
- Local moves: Omni-Bus loops cover lakeside areas but stop earlier than trains. Late night usually means a taxi or pre-booked car.
- IC cards: Suica or PASMO (phone or plastic) tap through trains/buses and pay at many shops and station lockers.
- Park rules: You’re in a national park—follow posted signs, keep noise low, and respect quiet hours.

If not aurora, what’s worth doing?
Kawaguchiko (Lake Kawaguchi)
- Ōishi Park & the north shore: Calm water and a wide view—great for Fuji’s reflection and sky color.
- Tenjōzan / Panoramic Ropeway: Lovely blue-hour scenes above the lake. Confirm last return before you go up.
Saiko & Shōjiko (quieter and darker)
- Saiko: Feels darker than central Kawaguchiko. Bring a headlamp with a red-light mode and mind your footing.
- Shōjiko: Minimal light pollution. On moonless summer nights, you can frame the Milky Way over the lake.
Motosuko (deep dark feel)
- The west shore feels the most “night-sky” of the Five Lakes. In winter, watch for ice and black ice. Park only in legal areas and keep noise down.
The science made simple
- Why it’s unlikely: The Northern Lights usually sit in a high-latitude “oval” far north of Japan. To see them from Fuji, that oval needs to bulge far south—this happens only during very strong solar storms.
- The Kp index: Kp runs from 0 to 9 and shows how disturbed Earth’s magnetic field is. Higher numbers mean a better chance of low-latitude aurora.
- A real outlier: On May 10–11, 2024, a G5 storm pushed aurora unusually far south and people in parts of Honshu captured faint, often magenta-tinted light. Interesting, historic—and not a regular event.
How to check on your date: Look at NOAA SWPC (Kp index and Aurora Viewline map) and NICT (Japan’s space-weather status). If Kp isn’t huge, enjoy the stars instead.
Alternatives by interest
- First-time night shooter: Stay near Kawaguchiko Station. Shoot blue hour at the north shore, then a short star session. Easy walk back, warm cocoa nearby.
- Dark-sky hunter: Base in Kawaguchiko. On a moonless night, taxi to Motosuko or Shōjiko. Bring layers, hand warmers, and microspikes in mid-winter.
- Family evening: Early dinner → quick lakeside stroll → last train or bus home. Keep it cozy and simple.
- Onsen fans: Do a short night photo session, then soak in an outdoor bath with a sky view.
Common mistakes (and polite night etiquette)
- Trusting viral posts without checking Kp. If the index isn’t extreme, aurora won’t happen here.
- Missing the last ride. Trains and local buses end earlier than big-city subways. Keep a taxi number handy.
- Parking where it’s not allowed. Use marked lots. National park rules exist to protect the area and local residents.
- Blinding everyone. Switch headlamps to red and point them down. Keep voices low near lakeside homes.
- Underestimating the cold. Shore winds bite. Bring a windproof jacket, hat, gloves, and grippy shoes.
FAQs
How rare is aurora near Fuji?
Extremely rare. Japan is far south of the usual aurora zone. It takes a major solar storm for even a faint display to be possible—and clouds or city glow can still spoil it.
If a big storm is forecast, where do people go?
Wide, open spots first: Kawaguchiko’s north shore, lakeside parks at Yamanakako, or darker shores at Motosuko and Shōjiko. Arrive early, stay quiet, and follow signs.
What’s the best backup plan if there’s no aurora?
A blue-hour session for Fuji’s reflection, then a short star shoot on a moonless night. It’s simple, gorgeous, and doesn’t depend on space weather.
Where can I check Kp and Japan-specific updates?
Use NOAA SWPC (Kp index and Aurora Viewline) and NICT (Japan’s live space-weather status). Check local cloud forecasts right before you head out.
Does the ropeway run at night?
Evening hours occur only on certain dates. Check the operator on your day, and plan to come down well before the last ride.
What’s the safest way back late at night?
If local buses have finished, use a taxi or pre-booked car. The Busta Shinjuku live board is helpful for returns to Tokyo when you’re taking the highway bus.
Can I fly a drone around the lakes at night?
Rules are strict and vary. National park areas often add extra limits. Assume you need permission and check official guidance before flying.
Which months give the clearest air?
Late November through February often brings drier air and clearer nights, but weather changes year to year. Pair your plan with the moon phase for best results.
Key Takeaways
- Aurora at Fuji is a unicorn. It needs an extreme solar storm, like the G5 event on May 10–11, 2024.
- Plan the sure thing. Choose moonless nights, winter clarity, and lake reflections around Kawaguchiko or Yamanakako.
- Check official dashboards. Look at NICT (Japan) and NOAA SWPC (Kp and viewline).
- Mind the basics. Confirm the last train/bus, park legally, and keep your lights and voices low.
