September 17, 2025: Our long day trip was marred by several downpours, but the weather cleared up upon arrival. We were incredibly lucky! 🥳 We visited Takachiho Gorge, Kamishikimi Kumanoza Shrine, and Aso Crater—every single attraction was truly visited! 👣 Thank you to our tour leader, Wang Qi, for your attentive care and to our driver for the long drive. Thank you all for making this trip possible!
