Koyasan from Osaka: The Perfect Summer Getaway
Koyasan from Osaka is the perfect summer escape.
If you’re planning to visit Osaka in summer… brace yourself.
I was there in July and August 2025, and let me tell you—it was boiling hot.
Think 36°C (96.8°F) of complete heat with over 80% of humidity. It was so uncomfortable, and yes.. everywhere I visited was so busy.
That’s why I looked for an escape, and the best one I found was Koyasan from Osaka—a sacred mountaintop temple town that gave me cool air, calm energy, and a break from the crowds.
What Is Koyasan?
Koya-san is a sacred mountaintop temple town in Wakayama Prefecture, founded over 1,200 years ago by the monk Kukai (also known as Kobo Daishi).
It’s one of the most important spiritual centers in Japan and home to over 100 Buddhist temples.
Even if you’re not religious, the calm energy of this place is something you can feel right away.

Okunoin: The Spiritual Heart of Koyasan
One of Koya-san’s two holiest sites is Okunoin, the mausoleum of Kobo Daishi, who is believed to be still meditating in eternal prayer.
To reach his resting place, you’ll walk a 2 km forest path lined with cedar trees over 700 years old, passing more than 200,000 tombs and memorials of everyone from emperors to commoners.
Near the mausoleum is the Toro-do (Lantern Hall), where two sacred lanterns have been burning for over 1,000 years:
- The Kishin Lantern (by monk Kishin Shonin)
- The Shirakawa Lantern (by Emperor Shirakawa)
These flames are known as the “eternal lights.”
Note: From Gobyo Bridge (御廟橋) onward, no photography is allowed —it’s considered sacred ground.
Why Koyasan is the Best Summer Escape from Osaka
| Feature | Osaka | Koya-san |
|---|---|---|
| Temperature | 35–38°C | 28–30°C |
| Crowds | Very crowded | Peaceful |
| Wait time for café/toilets | Often long | Minimal or none |
| Air | Urban heat | Crisp mountain air |

If you’re looking for a reset during your trip to Kansai, this is it.
Koya-san Temple Stays: Go Beyond Sightseeing
Over 50 temples at Koya-san offer overnight temple stays (shukubo) and spiritual experiences like:
- Ajikan meditation (unique to Shingon Buddhism)
- Shojin Ryori (Buddhist vegan cuisine)
- Morning prayers with monks at 6 AM
You don’t need to be religious to enjoy it.
You just need to be open to stillness, nature, and a different pace of life.
How Long Should You Stay?
| Travel Style | Time Needed | Highlights |
|---|---|---|
| Day Trip | 6–8 hours | Okunoin, Danjo Garan, cafés, shops |
| Overnight | 1–2 days | Temple stay, meditation, cultural immersion |
You can do it as a day trip from Osaka, but if you can stay overnight, do it.
Night in the forest is quiet, cool, and magical.
How to Get to Koyasan from Osaka
From Namba Station, Osaka:
- Nankai Koya Line to Gokurakubashi Station (1.5–2 hours)
- Take the Cable Car up the mountain (5 minutes)
- Short bus ride or walk to the temple town
Tip: Use the Koyasan World Heritage Ticket for discounted travel + unlimited local buses.
Tip: Ride the Special Train “Tenku” for a Scenic Experience
If your timing works out, consider taking the Tenku (天空) sightseeing train from Hashimoto Station to Gokurakubashi Station.
This special limited express train features:
- Huge panoramic windows on both sides
- Wooden interior with a calm, elegant vibe
- Forward-facing seats for enjoying the mountain views
- Announcements and displays in English and Japanese
- A slower, more scenic route through forests and bridges
Runs only 2–3 times a day, depending on the day and season—so check the schedule in advance. Highly recommended if you want to turn your trip to Koya-san into part of the adventure!
Good news:
- It’s almost never crowded, even in high season!
Downside
- Seats cannot be reserved online. You must call by 5:00 PM the day before to book, or try same-day purchase at the station (phone reservation required only for advance booking).
Pro Tip: How to Try Boarding Tenku on the Spot
Here’s a smart way to try riding Tenku without changing your entire plan:
- At Namba Station, buy your ticket all the way to Koyasan.
- Get off at Hashimoto Station (where Tenku departs).
- Inside the gate, go to the Tenku ticket booth and check availability.
- If seats are available, you can buy them for 520 yen (260 yen for children) right there.
- If it’s full, no worries—just wait for the next regular train to Gokurakubashi.
(As long as you haven’t exited the ticket gates, your main fare remains valid.)
That way, you don’t lose time or money—and you still have a chance at a relaxing, memorable ride through the mountains.
Day Trip Plan (6–8 hours on-site):
- Visit Danjo Garan and Okunoin
- Enjoy lunch at a local cafe
- Walk the peaceful streets
- Return to Osaka by early evening
Overnight Plan (1.5–2 days):
- Join the morning prayer at a temple stay
- Experience Shojin Ryori (monk meals)
- Take slow nature walks without time pressure
- Enjoy stars and silence at night
Final Thoughts: Koyasan is My Summer Travel Winner
I’ll be honest—after sweating in Osaka city and elbowing my way through tourist hotspots, I was ready to give up.
But Koyasan gave me space to breathe.
Literally cooler. Emotionally lighter.
And not swarming with tourists.
So if you’re planning a summer trip to Kansai, don’t skip this hidden gem.
It’s only a couple of hours from Osaka, but it feels like a whole new world.
You’ll come down the mountain with a clear mind… and no sunburn.
