ZANTER JAPAN: The Creator of Japan's First Down Jacket—A Legacy of History, Quality, and Evolution

Zanter Co., the company that crafted the cold-weather gear for both the first Japanese expedition to challenge the 8,163-meter-high Manaslu in the Himalayas and the first Japanese Antarctic Research Expedition, is renowned as the creator of Japan's first down jacket.

The original brand developed by Zanter Co. is ZANTER JAPAN.

We delved into the brand's roots, its world-class quality, and its current manufacturing philosophy by speaking with Naoya Hitaga from the sales department of Zanter Co., Ltd.

The Birth of Japan's First Down Jacket—A Story That Began with the Manaslu Expedition

"In 1953, the first Japanese Manaslu expedition team challenged the mountain, followed by the second team in 1954, and the third team successfully reached the summit for the first time in 1956. As it turns out, our company was the one that created the down jackets worn by all of these expeditions.

It all started back in 1947. During the post-war recovery period, the president of what would become Toyo Feather Industry Co., Ltd.—the parent company of Zanter—participated in the 'Red Feather Community Chest' drive as part of reconstruction and disaster relief efforts, supplying the raw materials for the red feathers. Around the same time, he recognized the insulating power of feathers and began supplying down futons to government agencies, which forged a key connection.

Additionally, we received a request from the Japanese Alpine Club, a public interest incorporated foundation established in 1905 with the goal of popularizing mountaineering as a sport, to produce cold-weather gear for the Manaslu expedition. This was the catalyst for creating Japan's very first down jacket.

Building on that success, in 1956 we also received a request from the Japanese Antarctic Research Expedition to create their cold-weather gear. We continue to produce the down wear they need for their activities in Antarctica to this day."

The 'BLIZZARD PARKA': Carrying on the DNA of the Manaslu Expedition

Now that we understand the history of ZANTER JAPAN, let's take a look at an item that carries on its DNA. We'll start with the 'BLIZZARD PARKA,' which traces its roots back to the down jackets of the Manaslu expedition.

"Back in 1953, high-tech nylon didn't exist yet, so we made down jackets using a fabric called 'Kasaji No. 5' (literally, 'No. 5 umbrella fabric').

Documents still preserved at Zanter today contain a note that says, 'Let's use a waterproof synthetic fiber.' It seems this umbrella fabric was the go-to water-repellent material at the time.

Also, the concept of a 'down pack[1]' didn't exist back then, so both the body and sleeves were sewn with a square quilt pattern, a clever design to keep the down filling from shifting.

A replica based on the original documents still exists, but the actual down jackets worn by the expedition team have not survived. I've been told that since they were custom-made, they had a more hand-sewn feel."

"The 'BLIZZARD PARKA' is a modern update that follows the design of the Manaslu expedition's down jacket. While retaining classic features like the square quilt pattern and waist pockets, the outer shell uses Toray's 'Delfy,' a waterproof, breathable, and windproof material.

A key feature is that while it's 100% nylon, it has the crispness and texture of cotton. The lining is a high-density polyester that allows you to feel the warmth of the down more intensely. The down itself is recycled, collected within Japan through our own unique channels, which I'll explain in more detail later.

For comparison, the container in the photo holds just 2 grams of down, whereas this jacket is filled with 180 grams. It's rated for temperatures around -30°C (Note: depends on layering and individual differences). While designed with city wear in mind, we've pursued truly professional-grade performance."

From the Antarctic Research Expedition to Your Everyday Life: The "ANTARCTIC EXPEDITION PARKA"

Alongside the Manaslu climbing expedition, ZANTER JAPAN's history of creating down wear for the Japanese Antarctic Research Expedition is an essential part of its story.

Next up, we're introducing the "ANTARCTIC EXPEDITION PARKA," a jacket that takes its cues from the designs for the Antarctic Research Expedition but is tailored for daily wear.

"It's based on ZANTER JAPAN's flagship Antarctic Research Expedition model, the 'JP-ORIGINAL DOWN.' For this parka, we used a fabric called 'chambray back satin,' which offers a more casual look and a distinctly textured feel.

Just like the BLIZZARD PARKA we mentioned earlier, the lining is a high-density polyester, and it's filled with recycled down.

It also features what we call a 'W-Tube Structure,' where two down packs are staggered. This design prevents heat from escaping through the seams and also prevents a bulky look, even with a generous amount of down fill.

The Antarctic model, the JP-ORIGINAL DOWN, is packed with 350g of down to handle temperatures as low as -60°C (Note: performance varies with layering and by individual). The ANTARCTIC EXPEDITION PARKA uses the exact same amount of down. While we've updated the materials and fine-tuned the accessories and details for everyday use, we've engineered it to maintain the same high level of performance."

The Secret to ZANTER JAPAN's Premium Recycled Down: Advanced Refining Technology

Two of the models featured today use recycled down. ZANTER JAPAN has its own advanced refining technologies and has been actively incorporating recycled down in recent years.

"We started expanding overseas a few years ago, and we've realized that in today's market, simply being 'Made in Japan' isn't enough. Companies are now expected to be actively engaged in SDGs (Sustainable Development Goals). This trend is particularly strong in Europe.

With that in mind, we started manufacturing in line with Goal 12 of the 17 SDGs: 'Responsible Consumption and Production.'

We believe it's crucial not just to make recycled down, but to maintain the high quality that ZANTER JAPAN is known for. That's why our recycled down is sourced exclusively from high-quality duvets collected by our parent company, Toyo Feather Industry Co., Ltd.

At our company, turning raw feathers into finished down involves a roughly 10-step process. We apply the same meticulous process to collected feathers—sorting, removing impurities, washing, and drying. The resulting recycled down achieves a 600 fill power [2] and provides outstanding insulation.

Zanter has always used high-quality feathers. In fact, it's said that high-quality feathers can last for 100 years. Down is a byproduct, and with new sourcing becoming more difficult, we believe recycled down is the way of the future."

Currently, ZANTER JAPAN products are available internationally, with retailers in countries like Germany, the United Kingdom, France, and Australia.

If there's one thing that defines ZANTER JAPAN, it's the outstanding quality of its down. Both its virgin and recycled down boast world-class quality.

The brand, which recognized the warmth and insulating properties of feathers shortly after World War II to create Japan's first down jacket, has evolved into a globally sought-after name in down wear, and it continues to innovate.
