For those paying by card on overseas sites
When using a Japanese credit card on an overseas e-commerce site (online shopping), the card company's fraud detection system will often be activated and the payment will be automatically blocked (rejected).
To ensure that your shopping goes smoothly, we strongly recommend that you contact us in advance using the following procedure.
1. Inform your card company of your planned use . This is the most reliable measure. If the cardholder informs the card company that they will be using the card overseas, they will be able to temporarily disable the security lock.
Contact details: Phone number on the back of the card or cardholder-only website/app
What to communicate:
"I plan to shop on an overseas website."
"Planned date of use (or period)"
Approximate payment amount
2. Why do I need to contact you in advance?
Card companies monitor suspicious activity 24 hours a day. If a payment is suddenly made on an overseas website using a card that has never been used overseas before, the system will assume that your card information has been stolen and misused, and will block the payment to protect your assets.
3. If your payment is rejected without contacting us <br/>If a payment error occurs, do not retry multiple times, but contact your card company immediately. If you can verify your identity, they will be able to lift the restriction immediately on the spot.

natural alkaline hot spring water
"Hot spring water" is natural water that gushes out from Tarumizu Onsen in Kagoshima Prefecture. The natural water that springs from a source 750 meters underground in the Sakurajima volcanic zone undergoes strict sanitary tests every day, and has a pH of 9.9 and a hardness of less than 2, making it the highest quality water in the world. It is a rare natural water with a limited amount, so it is truly a ``phantom water.''
Safety of hot spring water
Water is extracted and manufactured directly from the source in our own clean factory that has received an award for excellent food hygiene facilities (*).
In addition, periodic radioactivity tests conducted by an external inspection agency have resulted in non-detection of both radioactive iodine (iodine 131) and radioactive cesium (cesium 134 and cesium 137).
