Dear Ms. Xuan,
Thank you for choosing Kawara My An Onsen Resort for your family vacation. We greatly appreciate your comments, we will consider the issues you have raised to further improve our service and meet our customers' expectations. As for the blue color of the water, this is a characteristic of the hot mineral springs at Kawara My An, which is the characteristic color of sulfur, Ms. These sulfur and minerals are very good for the skin, making the skin smoother.
Looking forward to seeing you and your family again with the quality that meets your expectations.
Wishing you and your family health and happiness.
Best regards,
