Hello to all astronomy enthusiasts traveling around to enjoy the starry skies with your camping cars, and to those who are just starting to think about embarking on a stargazing journey!
2026 will be a special year that astronomy fans won’t want to miss. The reason is that the Perseid meteor shower on August 13th coincides with a new moon – a rare and ideal condition. This is a perfect opportunity to observe even faint meteors without the interference of moonlight. Additionally, there will be several “planet parades” visible throughout the year, making it a year packed with astronomical events.
With a camping car, you can transport your equipment to the best observation sites and enjoy the starry sky all night while staying warm inside the vehicle. This time, we’ll introduce recommended observation spots in the Kinki and Chugoku regions from a camping car traveler’s perspective.
Why Camping Cars Are Ideal for Stargazing
Serious stargazing requires going to places with minimal light pollution. Such locations are often in mountainous areas or highlands far from urban centers. With a camping car:
- Easy transport of heavy equipment: Telescopes, tripods, cameras, cold weather gear, and more
- Wait and rest inside the vehicle: No worries about freezing during winter nighttime observations
- Stay overnight at observation sites: Never miss the best viewing time before dawn
- Shelter during sudden weather changes: Peace of mind since mountain weather changes quickly
- Food and drinks always ready: Stay energized during long observation sessions
For example, during the Perseid meteor shower in August 2026, the peak is at 11:00 AM on August 13th (daytime), but the best observation time is from late night on the 12th to dawn on the 13th. At highlands over 800m elevation during this time, temperatures can drop to around 10°C even in midsummer. But with a camping car, when it gets cold, you can retreat inside for warm coffee and then head back out. This comfort level is unmatched by tent camping or regular car camping.

Chugoku Region Dark Sky Paradise [Prefecture Guide]
The Chugoku region has the Chugoku Mountains acting as a natural barrier blocking urban light, preserving extremely dark night skies.
[Okayama Prefecture] The Philosophy of Bisei
⭐ Bisei Astronomical Observatory & Starry Sky Park
Estimated SQM Value: 21.5+ (extremely dark)
Camping Car Suitability: ★★★★★
Bisei Town in Ibara City is one of the few places in Japan that has enacted a “Light Pollution Prevention Ordinance.” It boasts top-class darkness in the country.
Bisei Town’s Philosophy: Bisei Town has intentionally sacrificed convenience to “protect dark starry skies.”
- No public restrooms at Starry Sky Park → Use the open-air market’s restroom
- Limited accommodation (1 pension, training facility, several campgrounds)
- Nearest proper hotels are in Ibara, Yakage, Takahashi (30 min by car), Kurashiki, Fukuyama (1 hour by car)
How to View This: It may sound inconvenient, but this thorough elimination of light pollution is what achieves the miraculous darkness of SQM 21.5+. With a camping car, toilet (portable), bed, food – everything is self-contained. This “inconvenience” is not a problem at all.
Actual Observation Experience: Late night August 12, 2026, the night before the peak of the Perseid meteor shower. Arriving at Bisei Town Starry Sky Park’s parking lot, streetlights are completely off (by ordinance, lights are turned off after 10 PM). Only red-filtered flashlights are used.
At 1 AM, as the radiant point begins to rise, observe over 40 meteors in one hour. The synergistic effect of a new moon (moon phase 0) and SQM 21.5+ darkness allows you to catch faint meteors that are usually invisible with the naked eye. Even after the meteor trails disappear, Orion, Cassiopeia, and the Milky Way are clearly visible in the sky. This is the true essence of Bisei Town.
Bisei Astronomical Observatory’s 101cm Telescope: Observation using this large telescope is possible through public recruitment or group use (check in advance). You can observe planetary satellites and details of faint galaxies.
Camping Car Advantages:
- Recover from long-distance travel fatigue inside the vehicle
- Observe until the best time before dawn
- No facility constraints with portable toilet
Note: To protect Bisei Town’s dark sky, white lights are strictly prohibited. Always bring a low-brightness red LED light.

- White Light Use Prohibited
Flashlights, smartphone lights, car headlights – white light instantly destroys the dark adaptation of surrounding observers. Never use them. - Use Red LED Lights at Minimum Brightness
Red light has less impact on dark adaptation, but too bright is still bad. Adjust to minimum brightness, just enough to light the ground. - Turn Off Car Headlights Away from Observation Area
Turn off lights at least 50m away from observation area when parking. Move only with red light after arrival. - Be Considerate of Other Observers
If arriving late and others are already observing, be quiet. Close car doors quietly. Keep voices down. - Set Smartphone Screen Brightness to Minimum
Even when using constellation apps, set screen brightness to minimum. Use night mode (red display) if available.
Why Be So Thorough
Human eyes need at least 30 minutes for dark adaptation (getting used to darkness and being able to catch faint light). However, dark adaptation is completely lost with a moment of white light, requiring another 30 minutes to dark adapt again. At extremely low light pollution sites like Bisei Town, the number of stars visible with dark-adapted eyes is more than 10 times that of unadapted eyes. This difference is overwhelming.
⛰️ Mountain Area Observation
- Check Weather Forecast Until the Last Minute
Mountain weather changes quickly. Check 3 times: before departure, before arrival, before starting observation. Japan Meteorological Agency’s “High-Resolution Precipitation Nowcast” is useful. - Some Areas Have No Cell Signal
Share with family “when, where, and who you’re going with” before departure. Also communicate expected return time. - Emergency Communication System
Two-way radios are convenient when going in multiple vehicles. Satellite phones for serious expeditions. - Food and Water Reserves
No convenience stores in mountain areas. Carry at least 1 day’s food and 2L of water. Don’t forget emergency food. - Carry First Aid Kit
Keep a kit for scrapes, insect bites, sprains, and other minor injuries in the vehicle at all times.
❄️ Winter Observation
- Studded Tires or Chains Required
Highlands over 800m elevation may have snow and ice from November to April. Never go with normal tires. - Keep Plenty of Fuel
Fuel consumption increases with diesel heater use. Leave with a full tank and refuel when half empty. Running out of fuel is life-threatening. - Snow/Ice Escape Equipment
Keep shovel, tow rope, traction mats (boards to place under tires) on hand. Self-rescue is fundamental when stuck in snow. - Thorough Cold Protection
Sub-zero at elevations over 800m. Down jacket, gloves, knit cap, hand warmers, blankets are essential. Hypothermia is life-threatening. - Beware of Carbon Monoxide Poisoning
Ventilation is essential when using diesel heater inside the vehicle. Periodically check that the exhaust port is not blocked by snow.
☀️ Summer Observation
- Heat Stroke Prevention (During Daytime Travel)
Stay hydrated with water and salt, use air conditioning. Interior temperatures can exceed 50°C especially in August daytime. Take frequent breaks. - Insect Protection
Mountain areas have many mosquitoes, gnats, and horseflies. Defend with insect repellent spray, mosquito coils, long sleeves and pants. Keep anti-itch cream for bites. - Even High Elevations Get Cold at Night
Even in midsummer, nights drop to around 15°C at elevations over 800m. Always bring long sleeves and light fleece. - Beware of Thunderstorms and Sudden Downpours
Mountain areas commonly have thunderstorms from afternoon to evening in summer. Retreat inside the vehicle immediately when thunder is heard. - Bear and Wild Boar Precautions
Wild animals inhabit mountain areas. Don’t leave food outside. Carry bear bells and whistles. If encountered, retreat quietly.
Emergency Decision Criteria
- ⚡ Thunder starts → Immediately stop observation, retreat inside vehicle
- 🌧️ Visibility drops below 100m → Stop driving, wait in safe location
- ❄️ Can’t see ahead in blizzard → Stop on roadside, turn on hazard lights
- 🌡️ Body starts shivering → Sign of hypothermia, immediately get warm
- 📵 No cell service and feeling unwell → Don’t push it, descend mountain, move to populated area
💧 Dew is the Enemy When Observing at Coasts and Highlands
Dew occurs when water vapor in the air liquefies on the surface of cold objects (lenses, telescope tubes, etc.) as temperature drops. Humidity is high especially along coasts (Cape Shionomisaki, Lake Biwa shore, Sea of Japan side) and highland nights, creating conditions where dew easily forms. When telescope or camera lenses fog up, observation becomes impossible.
- Lens Heater (wrap around telescope, camera lens)
Most effective countermeasure. Keeps lens temperature above dew point, preventing dew. USB-powered type can be powered from portable battery. Wrap before starting observation. - Hair Dryer (use with portable power station)
Emergency treatment when dew has already formed. Dry slowly with low-temperature air. Hot air may damage optical systems, so be careful. - Towels (to wipe equipment)
Microfiber towels are best. Don’t scratch lens surfaces and have high absorbency. Bring multiple and replace when wet. - Store Inside Vehicle (when not observing)
During breaks and meals, move equipment inside. Minimize time exposed to outside air. Especially at dawn when temperature drops sharply and dew becomes severe. - Silica Gel (desiccant)
Put silica gel in equipment cases. Effective for moisture prevention during storage. - Use Dew Shields
Attach a dew shield (light shield tube) to telescope front. Prevents dew from falling directly on the lens.
Conditions Where Dew Easily Forms
- 🌊 Coastal areas (Cape Shionomisaki, Lake Biwa shore, Sea of Japan side) – Constantly high humidity
- 🏔️ Highland pre-dawn – Temperature drops sharply
- 🌧️ Night after rain – Humidity rises from ground evaporation
- ☁️ Sudden clearing after cloudy sky – Temperature drops sharply from radiative cooling
- 🍂 Autumn (Sep-Nov) – Large day-night temperature difference
Dew Prevention Don’ts
- ❌ Rapid drying with hot hair dryer → Lens coating may peel
- ❌ Wiping with tissue → Fibers stick to lens, causes scratches
- ❌ Continuing observation with dew formed → Moisture enters lens interior, causes mold
- ❌ Wiping with alcohol → Coating may dissolve
📦 Dew Prevention Kit (Recommended to Keep in Vehicle)
- ✓ Lens Heater ×2 (for telescope and camera)
- ✓ Microfiber Towels ×3 (always have dry ones ready)
- ✓ Portable Power Station (for heater power, 500Wh or more)
- ✓ Small Hair Dryer (for emergency treatment)
- ✓ Silica Gel (for equipment cases)
- ✓ Plastic Bags (protect equipment from sudden rain)
