- Hidden Gems: Visit the deli counter near the entrance of the specialty shop between 10:30 AM and 11:00 AM to find limited-edition kombu snacks and seasonal treats not listed on the main menu.
- Weekend Bonuses: On Saturdays and Sundays, the roadside station hosts a small farmers’ market from 10:00 AM to 12:00 PM near the parking area, offering fresh local produce and handmade items only available on weekends.
