Understanding the physical requirements for shipping is essential to estimate shipping cost accurately. Here is a breakdown of what to expect when sending an Oura Ring 4 package to Japan.

Metric Estimate

Always check the latest list of prohibited items to ensure no recent changes affect your shipment.

Import Duties and Customs in Japan

When the package arrives in Japan, it will be subject to local regulations. Generally, electronics like smart rings are subject to consumption tax (GST/VAT) rather than heavy import duties. However, the exact customs tax depends on the total declared value of the item. Being aware of the import tax threshold in Japan ensures there are no surprises when your comGateway shipment reaches Narita or Haneda.

By bypassing the myths of "difficult shipping," Japanese users can secure the Oura Ring 4 months before it hits mainstream local shelves, ensuring they remain at the forefront of the health technology curve in 2026.
