Ja-suke Profile

Setup in 30 Mins. A Villa-Like Space.
Your Family Memories Start with the Coleman Cocoon.

Hello! I’m [Ja-suke], a veteran camper from Japan. “Big tents are hard to set up…” “I’m worried about typhoons and rain…” I’ll blow those worries away. Today, I’m reviewing the “King of Tents” from Coleman Japan’s exclusive “Master Series.” It combines space, comfort, and reliability at the highest level. This isn’t your standard Coleman—it’s a beast built for Japan’s extreme four seasons.

Do you have these camping
worries?

  • I want a spacious tent, but I’m not confident about setting it up…
  • I can’t sleep peacefully because I’m worried about sudden rain or strong winds.
  • I’m tired of tents that are too hot in summer and freezing (with condensation) in winter!
  • I want a living room where the whole family can relax, eat, and talk comfortably!

The “Cocoon” Solves All
Those Problems!

The Cocoon isn’t just big. It’s the flagship of the Master Series, designed to satisfy even the most demanding veterans while wiping away beginner anxieties. Let’s look at the two main models available in Japan. Which one suits you?

4S Wide 2-Room Cocoon III

This is the standard flagship model of the Master Series, combining Coleman’s best technologies. Its appeal lies in its high basic performance for all seasons (4S) and reliability loved for years. It promises the best camping experience in any season, from humid summers to snowy winters.
Price: approx. 199,290 JPY

Cocoon DR Limited (Dark Room)

In addition to the exclusive color, this model features Coleman’s unique “Dark Room™ Technology” which blocks over 90% of sunlight. It drastically suppresses temperature rise inside the tent, making it cool like tree shade. Close the skylights, and it’s pitch black even at noon—perfect for sleeping in!
Price: approx. 275,000 JPY

4 Reasons Why the Cocoon is Called the
“King of Tents”

1. Overwhelming Space and Openness

Spacious Cocoon Interior

With a ceiling height of 220cm allowing adults to move standing up, and a vast living space comfortable for a family of 6. The walls rise almost vertically, so you can use the space effectively right to the corners. Enjoy camping without feeling cramped! 👨‍👩‍👧‍👦

2. Easy 30-Minute Setup (Even for Beginners)

Setting up the Cocoon

You might think, “I can’t handle something this huge…” but don’t worry. The poles and sleeves are color-coded, and there are assist functions specifically designed to help pitch it. It’s surprisingly smooth despite its massive size. Even I was surprised at first. 😲

3. Specs Built to Withstand Storms

Cocoon tent in the rain

The water pressure resistance is 3,000mm for the fly (10x a typical umbrella), and an insane 10,000mm for the floor! Plus, the thick aluminum alloy frame structure has cleared tests with wind speeds of 18m/s (approx 40mph). No matter the bad weather, inside the tent is a safety zone. You can sleep soundly. 🛌

4. All-Season Design for Any Weather

In summer, full mesh and large ventilation keep it cool. In winter, full skirts block cold drafts. Features like the cotton-blend inner tent reduce condensation. It’s packed with features to enjoy Japan’s four seasons! The Cocoon will be your best partner all year round. ☀️❄️

Detailed Features That Support Comfort

The reason it’s called the “King of Tents” lies in the details. The more you know, the more you’ll fall in love with this tent.

Skylights: See the Sky from Inside

Skylight view inside Cocoon

There are clear wall panels (skylights) in the living room ceiling. It lets in natural light while allowing ventilation. You can adjust it in 3 stages or close it completely for darkness. Perfect for checking the weather without going outside.

Versatile Canopy Arrangements

Canopy arrangement in rain

It comes standard with 3 canopy poles! You can extend the front and sides to create a huge living area protected from sun and rain. Personally, I use taller third-party poles (like DOD) to create even more height. It’s highly customizable.

Top-Tier Shelter Mode

Cocoon used as a shelter

If you remove the inner tent, it transforms into a massive shelter. Perfect for large group parties or sleeping on cots. You can change how you use it depending on your camping style.

Specs & Size: Will it Fit?

You know it’s big, but exactly how big? What about storage? Let’s answer those questions. Check if it fits in your car and campsite.

Interior size with furniture

Spacious interior. Plenty of room even with large tables.

Living Room SizeApprox. 400×400cm. Even with two 120cm tables and 6 chairs, you can still move around freely.
Bedroom SizeApprox. 360×240cm. Fits two double mats perfectly. 4 adults can sleep comfortably.
Overall SizeApprox. 670×400cm. Considering guy ropes, you need a site of at least 10m × 8m.
Packed SizeApprox. φ40×85cm, Weight approx. 35kg. Honestly, it’s heavy. But that weight equals stability. Auto-camping (car camping) is recommended.
Model NameCocoon DR Limited (Master Series)
Water PressureFly/Roof: approx. 3,000mm, Floor: approx. 10,000mm
Capacity5-6 People

Special Dark Room Moments…
and a Funny Mistake 😅

Dark Room technology isn’t just about staying cool. Using that “darkness” makes camping more fun! But, I also have a funny failure story due to that darkness… (lol).

Planetarium & Movies at Noon!

If you close the skylights on the Cocoon DR, it becomes pitch black even at midday. In winter, you need a lantern even during the day! We use a portable projector to project a starry sky on the ceiling or have a movie marathon… it’s like a secret base, and the kids absolutely love it!
However, it’s so dark that you lose track of time inside. Great for sleeping in, but don’t forget an alarm if you want to be active!

I Messed Up… My Tearful Story

One winter night, I saw twinkling stars inside the tent… Yes, I had burned a small hole in it! Because it’s a Dark Room tent, even the tiniest pinpoint of light (from outside) stands out incredibly well inside (bitter laugh). Be careful with fire near the tent! Orz

Real Voice of a User (Q&A)

Can one person really set it up?

Yes, once you get used to it! But for safety, I recommend doing it with two people initially. Especially on windy days, it’s dangerous, so never force it.

Any useful tools for setup?

I highly recommend bringing a small step stool! The Cocoon is tall, so putting on the Roof Fly (the top sheet) at the end is tough if you aren’t tall. Just one stool makes the work much easier and safer.

Is storage difficult?

The bag is relatively spacious, so it’s okay! The trick is to squeeze the air out firmly while folding. Using the pole case as a core to roll it up helps make it compact.

Is it really comfortable in the rain?

Absolutely! The waterproofing is perfect (Master Series quality). Since the living room is so huge, “Hunkering Down” camping (playing games or watching movies inside while it rains) is actually super fun.
