Our visit to Yutoku Shrine was especially memorable thanks to Helen’s well-delivered explanations and insights. The tour of the sake factory was also a highlight — we enjoyed learning about the production process and the tasting session. Ending the day at the outlet was convenient and relaxing, and the timing was managed perfectly.
