Yamaroku Shoyu is a distinguished traditional soy sauce brewery located on Shodoshima Island, a place historically significant for its soy sauce production. What sets Yamaroku apart is its unwavering commitment to the centuries-old method of brewing in large wooden barrels, known as 'kioke'. These barrels, some over 150 years old, harbor unique microbial cultures essential for the distinct flavor of their soy sauce, a craft increasingly rare in modern production.
Visitors consistently praise the engaging and informative tours offered at Yamaroku Shoyu. Many reviewers highlight the excellent English-speaking guides who provide fascinating insights into the brewing process, the history of the company, and the importance of traditional methods. The aroma inside the factory, described as 'brothy, sweet, and rich,' is a memorable part of the experience. After the tour, the opportunity to taste and purchase various soy sauce products is a major draw, with visitors often recommending buying directly from the factory shop.
To make the most of your visit, allocate about 1 to 1.5 hours for the tour and tasting. Reviewers suggest visiting during the day to fully appreciate the factory's operations. It's advisable to bring a decent map or use GPS, as some visitors found the factory a bit challenging to locate, especially when cycling. Don't forget to try the soy sauce ice cream, which is frequently mentioned as a unique and delicious treat.
Yamaroku Shoyu is located at 1607 Yasuda, Shodoshima-cho, Kagawa Prefecture. While specific public transport details are not widely mentioned in reviews, several visitors cycled to the factory, indicating it's accessible by bicycle, likely from nearby towns or ferry terminals on Shodoshima. Given the island setting, renting a car or scooter might offer the most flexibility for reaching the brewery and exploring the surrounding area.
A common point for visitors is the potential language barrier if an English-speaking guide is not available, though many reviews confirm the presence of such guides. To mitigate this, consider calling ahead to inquire about English tour availability, especially if you are part of a larger group. Some visitors also noted that while the factory is 'working,' it maintains a welcoming atmosphere for tourists, balancing authenticity with visitor experience.
