Diplomatic career

Tomita entered the Ministry of Foreign Affairs (Japan) in the late 1970s and built a career across East Asian and transatlantic portfolios. Early assignments included service at the Japanese embassies in Beijing and Seoul, and at the consulate-general in San Francisco. He held director-level roles covering relations with the United States, China, and the Republic of Korea, and contributed to negotiations involving the Trans-Pacific Partnership and trade dialogues with the European Union and the United Kingdom. Tomita also served in multilateral postings at the Japanese mission to the United Nations in New York City and engagements with NATO liaison offices in Brussels. Within the Ministry of Foreign Affairs (Japan) headquarters he oversaw divisions connected to legal affairs, treaty implementation, and bilateral policy, liaising with the Prime Minister of Japan's office and the Cabinet Secretariat.

Tenure as Ambassador to the United Kingdom

Appointed Ambassador to the United Kingdom following senior ministry service, Tomita presented credentials to Buckingham Palace and conducted high-level talks at Downing Street and with officials from the Foreign, Commonwealth & Development Office. His ambassadorship emphasized closer ties with the United States, cooperation on regional security with Australia and India under frameworks linked to the Quad, and enhanced economic linkages with the European Union and United Kingdom. He organized state visits involving delegations from the Diet (Japan), the Prime Minister of Japan, and business missions from the Japan External Trade Organization, while coordinating cultural exchanges with institutions such as the British Museum and the Royal Opera House.

Key policy initiatives and positions

Tomita advanced initiatives on security cooperation, trade liberalization, and people-to-people exchanges. He supported joint statements and working groups with the United States Department of State, the Foreign, Commonwealth & Development Office, and counterparts from France, Germany, and Italy on regional stability in East Asia involving Taiwan and the Democratic People's Republic of Korea.

Some opposition politicians in the Diet (Japan) and commentators in outlets connected to the Financial Times and the BBC questioned aspects of decision-making tied to defense-related dialogues with the United States and procurement discussions involving Japanese firms and suppliers in Europe. Debates also arose over diplomatic communications handled during crises involving the Democratic People's Republic of Korea and disputes adjudicated at the World Trade Organization.
