Kosanji Museum was a truly impressive place, with historical buildings and beautiful gardens as its highlights. The temple architecture features elaborate decorations down to the smallest details, making it a captivating sight. The museum's diverse exhibits offered a wonderful opportunity to experience traditional Japanese culture. The staff were also very kind and courteous, which made for a comfortable visit. It's a highly recommended spot that you should definitely visit when sightseeing in Hiroshima. Don't miss the Hill of Hope (Miraishin no Oka) either. It's a modern garden lavishly built with white Italian marble, where you can enjoy a fantastical atmosphere as if you've stepped into another world. The contrast with the blue sky is beautiful, making it a popular spot for photos. From the top of the hill, you can enjoy a spectacular view of the Seto Inland Sea, making it also recommended for those who want to spend some quiet time. I felt it was a special space where art and nature merge, and well worth a visit.
