For those making card payments on overseas websites
When using a Japanese credit card on an overseas e-commerce site (online shopping), the card company's fraud detection system often kicks in, automatically blocking (rejecting) the payment.
To ensure your purchase goes through smoothly, we strongly recommend making a "prior notification" by following the steps below.
1. Notify your card company of your "planned usage."This is the most reliable measure. By informing the cardholder that you will be using the card overseas, they can temporarily configure the security settings to prevent it from being locked.
Contact: The phone number listed on the back of your card, or the cardholder-exclusive website/app.
Information to provide:
"I plan to make a purchase on an overseas website."
"Planned date (or period) of use."
"Approximate payment amount."
2. Why is prior notification necessary?Card companies monitor suspicious activity 24/7. If a card that has never been used overseas suddenly makes a payment on an international site, the system will assume that "card information has been stolen and misused" and will stop the payment to protect your assets.
3. What to do if payment is rejected without prior notification.If you encounter a payment error, do not repeatedly retry. Contact your card company immediately. Once your identity is confirmed, they can lift the restriction right away.

Natural Alkaline Hot Spring Water
"Onsensui" is natural water that springs from Tarumizu Onsen in Kagoshima Prefecture. This natural water, which springs from a source 750 meters underground in the Sakurajima volcanic belt, undergoes rigorous daily sanitation checks and boasts a pH of 9.9 and hardness of 2 or less, making it a world-class quality water. Due to its limited supply, it is truly a "phantom water."
Safety of Hot Spring Water
We source water directly from the spring and manufacture it in our clean factory, which has received an award for food hygiene excellence (*).
In addition, regular radioactivity inspections by external testing organizations have shown non-detectable results for both radioactive iodine (Iodine-131) and radioactive cesium (Cesium-134 and Cesium-137).
*Awarded by the Kagoshima Prefectural Food Hygiene Association
