Charcoal-Grilled Gyutan Bento — Kobayashi (Self-Heating)

This entry is Kobayashi’s Sumibiyaki Gyutan Bento: charcoal-grilled, salt-seasoned beef tongue over barley rice in a self-heating container. The operator lists ¥1,880 including tax and an approximately five-to-six-minute heating time after pulling the cord. It is different from the company’s cheaper Amiyaki version and its non-heating tongue bento. Product page checked 1 November 2026. The operator has shops connected to Sendai Station, but check the exact shop’s selection before relying on this particular box. Follow the package instructions and eat within its stated use-by period; the heater is not a substitute for appropriate storage.
