About this story
Emperor Naruhito is the 126th Emperor of Japan and head of state of the world's third-largest economy. He and Empress Masako are on an official state visit to Belgium — the most formal category of diplomatic visit, involving a full programme of official receptions, meetings with the head of government, a state dinner, and often a joint communiqué.
How to read this story
The history
1866: Japan and Belgium sign their first Treaty of Amity, Commerce and Navigation — among Meiji Japan's earliest formal diplomatic agreements with a European nation. 1885: Japan establishes a permanent diplomatic mission in Brussels. 1952: Belgium is among the first European nations to re-establish full diplomatic relations with Japan after the San Francisco Peace Treaty. 1985: Crown Prince Akihito and Crown Princess Michiko visit Belgium in a landmark royal exchange. 2019: Naruhito ascends to the Chrysanthemum Throne on 1 May — the first Japanese Emperor to succeed following his father's historic abdication, the first in approximately 200 years. 2021: The Japan-EU Economic Partnership Agreement (EPA) enters full force, eliminating most tariffs between Japan and EU member states including Belgium. 2023: Japan-EU Security Partnership upgraded; Belgium formally supports Japan's Indo-Pacific posture and Japan-NATO cooperation framework. 23 June 2026: Emperor Naruhito and Empress Masako are received by King Philippe and Queen Mathilde at the Royal Palace of Brussels in an official state visit.
Regional impact
Japanese corporations are significant economic actors in Belgium. Toyota's European headquarters in Brussels employs hundreds of staff. Mitsubishi, Panasonic, and Honda all maintain Belgian operations. Japanese tourism — particularly to Bruges, Brussels and the Ardennes — contributes tens of millions of euros annually to Belgian hospitality revenues. The estimated 5,000 Japanese nationals living in Belgium represent a stable, long-established community with professional ties to EU institutions, Japanese multinationals, and diplomatic missions. The visit is expected to yield a joint communiqué on trade facilitation and bilateral cultural exchange.
International angle
Japan is the world's third-largest economy (nominal GDP approximately 4.2 trillion dollars, 2025) and one of the EU's most important strategic partners. The visit comes at a moment of convergence between Japanese and European strategic interests: both are concerned about Russian aggression in Ukraine, both are recalibrating supply chains away from single-country dependence on China, and Japan's 2022 National Security Strategy explicitly named Europe as a partner in upholding a rules-based international order. Emperor Naruhito's visit to the seat of the EU and NATO carries a symbolic dimension that extends well beyond bilateral trade — it is a statement about which international order Japan wishes to uphold.
What this means for you
Belgian businesses with Japanese partners should note that state visits typically generate a window of heightened diplomatic attention that can accelerate pending negotiations and agreements. Companies in pharmaceuticals, agri-food, automotive components, and professional services operating in both markets may find this a favourable moment to advance discussions at ministerial level. For Belgian residents of Japanese heritage or with family ties to Japan, the visit is an opportunity for community events aligned with the Imperial programme.
