Yes, there is a small but notable price difference between the Nozomi (the fastest Shinkansen service) and the Hikari (the semi-fast service). Generally, a reserved seat on the Nozomi carries a "surcharge" of approximately ¥200 to ¥700 more than a Hikari seat, depending on the distance traveled. Interestingly, if you are traveling in a non-reserved seat, the price is identical for both trains. For travelers using the Japan Rail Pass, the Hikari is fully covered, whereas the Nozomi requires a significant supplemental "Nozomi/Mizuho" ticket. In 2026, many locals prefer the Nozomi for its frequency and speed (reaching up to 300 km/h), while tourists and budget-conscious travelers often opt for the Hikari or the all-stops Kodama to save on seat reservation fees.
