Ready for a crash course in shoyu? Stop by Kinbue Soy Sauce Park, run by a 230-year-old soy sauce brewery, where you can learn about the process of making Japanese seasonings from bean to bottle. Plus, you can try a variety of condiments and take home souvenirs such as the brand's tsuyu soup, sesame dressing and shoyu-flavoured baumkuchen.
You can check the schedule for the factory tour on Kinbue Soy Sauce Park's official website.
