Insider Tips
Visit early for the best selection and check seasonal updates for limited-time offerings at Shiroishi roadside station.
- Best Arrival Time: Visit between 9:00 AM and 10:00 AM on weekdays to secure the freshest selection of seasonal vegetables, as inventory increases throughout the morning and popular items like leafy greens and turnips are often restocked early.
- Hidden Gems: Look for the renkon nikuman (lotus root meat bun) at the deli counter—this limited-time seasonal item is only available when the station’s food truck or special event (like the recent balloon festival) is in session, and it sells out quickly.
- Seasonal Product Tip: Purchase fresh lotus root (renkon) and turnips in November, as these are highlighted in the station’s seasonal updates and are among the first root vegetables to become available after summer harvests end.
- Weekend Special: Attend the monthly Shiroishi Harvest Festival (scheduled for late October and early November) to access exclusive local produce and special tasting events not available on regular days.
- Restaurant Timing: Check the 2nd floor restaurant, Tannaka Cafe 360°, for its limited weekday openings—especially avoid visiting on the third Wednesday of each month, as it is a regular closure day.
- Product Availability Alert: Buy the seasonal Ichiko (a local sweet potato variety) in October and November, as it is only available during these months and is not restocked after the harvest season ends.
- Best Shopping Window: Visit the second-floor market counter during the morning hours (before 11:00 AM) to get the full selection of regional specialties like rice, corn, and onions, as these items are often sold out by midday.
