After placing an order with KKDay, I received a paper voucher within two days. Upon arriving in Japan, I exchanged it for a JR Pass at the green window and was able to start using it immediately. It's quite convenient, and I recommend using it if it suits your needs!
We chartered a car from Fukuoka to a hot spring hotel in Yufuin. We first visited Dazaifu Tenmangu Shrine. Because of the heavy traffic on Saturday, the driver suggested adjusting the itinerary and having lunch at a rest stop along the way before heading to Yufuin to avoid having to queue for lunch. After arriving, we parked the car in the parking lot in the middle of Yunotsubo, which was only a ten-minute walk from Lake Kinrin, which was great.
The stalactite cave elevator leads to Akiyoshidai Quasi-National Park. Following the trail to the top, you'll find an endless panorama of breathtaking beauty that you absolutely must experience in person.
People rarely mention the Kanmon Strait Museum when visiting Moji Port, so I didn't have high expectations at first, but it turned out to be surprisingly fun! First, the interactive experience machines are diverse. Upstairs, the large screen shows a historical animated series (super well-made!) and ocean-themed music animations every half hour. Different themed time slots correspond to different games. My favorite was the head-swapping game in the historical series 😂 I never got tired of just drawing characters! While the museum's collection isn't huge, it provides a good understanding of the area's history. Downstairs, there are also ocean-related interactive games, more geared towards family-friendly experiences. In short, I highly recommend it; an afternoon is definitely not enough to see everything! 😖
