I often take day trips in Japan, but this Gunma day trip was a real surprise. It wasn't your typical visit to tofu skin or wineries; it was a much closer connection with nature, showing you the remote mountains and wilderness of the Japanese countryside – something most day trips don't offer. It was truly unique and well worth the trip. Our guide, Cathy Cheung, was incredibly patient and professional, providing excellent service. Thank you, Cathy, for your care; I hope to meet you again sometime.
