As of early 2026, the answer is yes, but with a major caveat regarding timing. Since the massive 70% price hike in late 2023, the Japan Rail Pass is no longer an "automatic" money-saver for every traveler. You should buy it in advance—specifically 30 to 60 days before travel—through the official JR-West or JR-East websites to take advantage of the digital seat reservation system. A supportive peer "math" reminder: you should only buy the pass if your planned travel (e.g., Tokyo to Osaka to Hiroshima and back) costs more than the pass price (approx. 50,000 JPY for 7 days). In 2026, it is often cheaper for tourists to buy individual Shinkansen tickets or regional passes (like the Kansai-Hiroshima Pass) instead of the "All Japan" version. If you do decide it’s worth it, buying via the official site allows you to book seats online before you even arrive in Japan, which is essential during peak seasons like Cherry Blossom or Golden Week.
