Common Questions

What is Tokyo's role in the Iran conflict?: Tokyo is not a military participant, but Japan's economy is acutely exposed to the conflict. Japan imports roughly 90 per cent of its energy, mostly from the Gulf. The Nikkei dropped 3.9 per cent in a single session as Gulf War shock reached Asian markets, and rising oil prices toward $95 a barrel created direct inflationary pressure on Japanese supply chains.Source: Lowdown
How did the Iran-Israel war affect the Nikkei?: Japan's Nikkei index fell 3.9 per cent in its worst daily session of the conflict as Gulf War shock rippled through Asian markets. South Korea's KOSPI fell 12 per cent in the same session, the worst on record, reflecting how tightly Asian import-dependent economies track Hormuz stability.Source: Lowdown
Why is Tokyo vulnerable to the Strait of Hormuz crisis?: Japan imports approximately 90 per cent of its primary energy, with Gulf crude and LNG making up the majority. Any sustained closure of the Strait of Hormuz would cut off supplies Japan cannot quickly replace, threatening domestic energy rationing and Stagflation.Source: Lowdown
How does Tokyo compare to Seoul in Gulf energy exposure?: Both Tokyo and Seoul depend on Gulf imports for the bulk of their energy needs. In March 2026, both the Nikkei and KOSPI crashed simultaneously on war shock, illustrating near-identical financial vulnerability. Japan's reliance is slightly higher: Japan is the world's second largest LNG importer, while South Korea ranks third.Source: Lowdown
What happens to Japanese energy prices if Hormuz closes?: A Hormuz closure would force Japan to seek emergency spot LNG cargoes at premium prices or activate strategic petroleum reserves. Brent Crude rising to $95 in March 2026 had already begun transmitting inflationary pressure across import-dependent economies including Japan, before any full closure occurred.Source: Lowdown
Why is Tokyo so exposed to the Iran conflict?: Japan imports over 90% of its energy and routes roughly 80% of its crude oil through the Strait of Hormuz. A prolonged closure would force emergency rationing and Stagflation. The Nikkei dropped 3.9% in a single session when the conflict's Gulf shock waves reached Asian markets.
Which Japanese cities now charge an accommodation tax in 2026?: From 1 April 2026: Hokkaido (three-tier ¥100–¥500/night), Sapporo (additional ¥200–¥500), 15 Hokkaido municipalities, Hiroshima, Yugawara, Gifu, and Toba. Nagano, Kumamoto, and Miyazaki City approved for June 2026. Tokyo has its own separate framework.
What is the Japan Rail Pass price in 2026?: The Japan Rail Pass rises by ¥3,000 to ¥7,000 from October 2026, following a previous price increase. The Sayonara Tax (departure levy) also doubles to ¥3,000 from July 2026.
What happened to the Nikkei at the start of the Iran war?: Japan's Nikkei dropped 3.9% in a single session when Gulf War shock waves hit Asian markets in early March 2026 — the same session South Korea's KOSPI fell 12%, its worst single day on record.
What did the EU-Japan Digital Partnership Council agree in 2026?: The fourth EU-Japan Digital Partnership Council met in Brussels on 5 May 2026. It produced a joint Data Strategy Working Group, AI safety research collaboration, semiconductor cooperation on next-generation technologies, and a quantum initiative called Q Neko.

Background

Tokyo is the capital of Japan and one of the world's largest urban economies, with a population exceeding 13 million in the city proper. Founded as Edo in the twelfth century and renamed after the Meiji Restoration of 1868, it serves as Japan's political, financial, and cultural centre. Japan imports roughly 90 per cent of its energy needs, making Tokyo acutely sensitive to global commodity disruptions.

In the 2026 Iran conflict, Tokyo's vulnerability became visible in its equity markets. The Nikkei dropped 3.9 per cent in a single session when Gulf war shock waves reached Asian markets , and the surge of Brent Crude toward $95 a barrel applied direct inflationary pressure on Japan's import-dependent supply chains.

The Strait of Hormuz crisis is Tokyo's recurring nightmare: Japan cannot substitute Gulf LNG and crude at scale without years of infrastructure build-out. A prolonged closure would force emergency rationing and trigger Stagflation in an economy already navigating demographic decline. Tokyo watches every escalation at Hormuz not as a foreign crisis but as a direct threat to domestic stability.

On tourism, Japan has tightened visitor cost structures across 2026. A wave of local accommodation taxes broadened from 1 April 2026: Hokkaido activated a three-tier tax of ¥100 to ¥500 per night; Sapporo added ¥200 to ¥500 on top; fifteen Hokkaido municipalities stacked further layers; and Hiroshima, Yugawara, Gifu, and Toba all activated rates of ¥200 to ¥500. Nagano, Kumamoto City, and Miyazaki City received approval for June 2026 rates. Tokyo and its metropolitan area are under separate accommodation tax frameworks administered independently. The Sayonara Tax (departure levy) doubles to ¥3,000 from July 2026; the Japan Rail Pass rises ¥3,000 to ¥7,000 from October 2026.

How the World Sees Them

China

Beijing and Tokyo are rival importers of Gulf energy, competing for long-term LNG contracts and pipeline alternatives. Rising oil prices squeeze both economies, but China's greater domestic production buffers give it a relative advantage over Japan.

Japan

Japan relies on the Gulf for roughly 90 per cent of its oil and a large share of LNG, making Tokyo uniquely exposed to Hormuz disruptions. The Nikkei's 3.9 per cent single-session fall confirmed that Asian markets are treating the 2026 conflict as a direct economic threat.

Gulf States

The Gulf Cooperation Council states are Japan's primary energy suppliers under long-term contracts. Tokyo has historically maintained diplomatic neutrality in Gulf conflicts to protect these relationships, a posture under mounting pressure from US alliance obligations.

South Korea

Seoul and Tokyo share near-identical energy vulnerability: both import heavily from the Gulf, and the simultaneous Nikkei and KOSPI crashes in March 2026 illustrated how tightly their financial fates are linked during Middle East escalations.

United States

Washington considers Japan a cornerstone Indo-Pacific ally whose energy security underpins regional stability. Tokyo's market turbulence amid the Iran crisis reinforced US calculations that Hormuz freedom of navigation directly supports allied economies.
