Japan ↗IC cards (ICOCA/Suica) are topped up with cash at station machines.
Japan ↗Smoking while walking is banned in most city centres; use designated areas.
Japan ↗Shinkansen bags 160–250 cm (L+W+H) need a seat reserved with the oversized-baggage area.

The Izu Islands are a volcanic archipelago southeast of Tokyo, known for hot springs, dramatic coastlines and marine sports such as diving, surfing and fishing. Base on the largest island, Oshima, for easy ferry links, and take day‑trips to the smaller islands.
