Why I finally decided to ship the Oura Ring 4 to Japan and the 6 things that surprised me

The aura of the Oura Ring 4

I have been a fan of wearable technology for years, but the 2026 release of the Oura Ring 4 felt different. My interest was piqued when I saw the shift to a fully titanium interior, replacing the plastic molding of the previous generation. It is not just about aesthetics; the new sensor platform is significantly more accurate, especially for sleep tracking and heart rate variability. I always keep an eye on us trends to see what health tech is gaining traction, and this ring is currently dominating the conversation.

More about shipping to Japan

The ring feels more like a piece of jewelry than a medical device. I noticed that the thinner profile makes it much more comfortable for 24/7 wear compared to the bulkier alternatives I have tried in the past. We often look for tech that blends into our lives, and Oura seems to have achieved that balance this year.

Why Japan is still waiting

One thing that puzzled me was why I couldn't simply walk into a store in Shinjuku or order from a local Japanese website to get one. Despite the massive popularity of health trackers here, the Oura Ring 4 has yet to see a full-scale local release in early 2026. I realized that if I wanted to stay ahead of the curve, I would have to look toward the United States. Many of the most innovative features are rolled out there first, and Japan often faces a lag of several months or even a year.

How I found my way to US stores

I decided to shop us store directly to secure my size and preferred finish. I found that the selection on the official US Oura site and major American retailers was far superior to the limited gray-market imports available locally. To make this work, I needed a reliable freight forwarder. I chose to use comGateway because they provided me with a tax-free us address in Oregon, which saved me from paying US sales tax on an already premium-priced item.

My shipping estimates for the Oura Ring 4

Before I committed to the purchase, I made sure to estimate shipping cost using the online tools available. Here is the data I used for my calculations:

Because the item is quite light, I found that I could actually save more by using a parcel forwarding service that allows for consolidation. If I had bought a second charger or an extra strap, combining them into one shipment would have reduced the per-item cost significantly.

The logistics of lithium batteries

I had to be careful about the battery. The Oura Ring 4 contains a small lithium-ion battery. Most international shipping regulations, including those followed by any reputable package forwarding company, allow for these as long as the battery is contained within the equipment. My ring fell under the UN3481 classification. I made sure to confirm that my chosen courier could handle this specific category to avoid any delays at the airport.

The step-by-step guide I followed

If you are wondering how it works, the process was surprisingly linear. First, I registered for an account to get my US address. Then, I placed my order on the Oura website using that address. Once the package arrived at the warehouse, I was notified and could choose my shipping speed to Japan. This step-by-step guide is essentially the standard procedure for anyone looking to forward packages across the Pacific.

What I learned about import duties in Japan

One of the most important things I researched was the potential for import duties. In Japan, personal imports are generally exempt from customs tax if the value is under ¥16,666. However, the Oura Ring 4 exceeds this threshold. I had to account for the 10% consumption tax (GST/VAT equivalent) upon arrival. I recommend checking our guide on import tax to understand how the Japanese Customs office calculates the value based on 60% of the retail price for personal use items.

My package arrived at my door in Tokyo within five days of leaving the US warehouse. The convenience of having a parcel forwarding service manage the documentation made the entire experience feel seamless. I am now enjoying the most advanced sleep metrics available in 2026, all because I looked beyond my local borders.
