The direct answer: a reserved seat on the Tokyo–Hiroshima Shinkansen costs about ¥19,560 one-way and takes 3 hours 47 minutes on the direct Nozomi. This is a longer, pricier leg than Tokyo–Kyoto or Tokyo–Osaka — which is exactly why it's the route that tips the JR Pass math, especially if Hiroshima is one stop on a longer loop rather than a standalone round trip.

≈ ¥26,820
Is the JR Pass Worth It — For This Route?
A 7-day JR Pass costs ¥53,000 (since the October 2026 price increase). A Tokyo–Hiroshima round trip bought separately runs roughly ¥39,000. On its own, that still falls short of the Pass price — but Hiroshima is rarely a standalone trip.
Add Kyoto or Osaka as a stop on the way — a Tokyo → Kyoto → Hiroshima → Tokyo loop — and the separate-ticket total climbs close enough to ¥53,000 that the Pass usually wins, especially once you factor in the free seat reservations and the flexibility to hop off anywhere along the way.

How to Actually Book It
Same-day, no JR Pass: buy at any JR ticket machine or staffed counter (English available) — no advance booking needed for most dates.
With a JR Pass: exchange your voucher for the physical pass at a JR office on arrival, then reserve Hikari or Sakura seats for free at any JR ticket counter or machine.
Going direct, no transfer: skip the Pass-covered Hikari/Sakura and just buy a Nozomi ticket — on a single Tokyo–Hiroshima trip, saving over an hour is often worth more than the fare difference.
Rush hour and holidays (Golden Week, Obon, New Year): reserve at least a few days ahead — non-reserved cars do fill up standing-room-only on this longer route.
