The UK ambassador to Japan has issued a stark warning: Donald Trump’s public disdain for Japanese anime could have real consequences for trade ties between Tokyo and London. In a candid interview with the Financial Times, Ambassador Julia Longbottom described the former US president’s comments as “unhelpful” and “potentially damaging” to the delicate balance of economic diplomacy in the region.
Let’s be clear. This isn’t about cartoons. This is about hard cash. Anime is a multi-billion pound industry, a cornerstone of Japan’s soft power and a significant export sector. When a figure as influential as Trump dismisses it as “weird” or “childish”, he risks alienating a key ally and undermining the very cultural exchanges that underpin trade agreements. The ambassador’s remarks come as the UK and Japan finalise a new economic partnership agreement, with digital services and creative industries at its heart.
Markets hate uncertainty. And Trump’s unpredictability is a known factor. His off-the-cuff remarks have a history of moving markets, from tariffs on steel to tweets about Kim Jong-un. Now, with anime in his crosshairs, investors in Japanese entertainment stocks are jittery. Shares in Toei Animation and Sony have dipped 2% and 1.5% respectively this week on fears that a US trade spat could spill over into the UK-Japan relationship.
The ambassador’s intervention is rare and significant. Diplomats don’t usually wade into cultural controversies unless the bottom line is at stake. Her message is clear: the UK cannot afford to pick sides in a culture war when economic gains are on the table. Japan is the UK’s fourth largest non-EU trade partner, with bilateral trade worth £30 billion annually. Any disruption, even rhetorical, is a risk that the City of London will not take lightly.
Inflationary pressures already loom. The Bank of Japan is grappling with rising prices, and a weakening yen is making exports cheaper but imports more expensive. If Trump’s animosity leads to a boycott or regulatory hurdles for Japanese anime abroad, that could hit Japan’s export revenues, forcing the BoJ to adjust monetary policy. Higher interest rates in Japan would then ripple through global bond markets, affecting gilt yields and capital flows.
The prime minister’s office has so far remained silent, but privately officials are briefing that they are ‘monitoring the situation closely’. That’s code for damage control. The UK’s trade envoy to Japan is reportedly scheduling meetings with anime industry executives to reassure them that British trade policy remains separate from US political theatre.
Let’s not forget the bigger picture. Trump’s brand of isolationism has already cost America influence in the Pacific. The UK, post-Brexit, is positioning itself as a free-trading, nimble partner to Asia. We cannot afford to be caught in the crossfire of a petty culture war. The ambassador’s warning is a shot across the bow: trade trumps tribalism.
The bottom line? Anime is not just entertainment. It is a £20 billion global industry, and Japan holds a 60% market share. For the UK, courting Japanese investment in AI and gaming is a priority. Trump’s comments are a distraction we don’t need. The City will be watching the next bout of trade talks with Japan very closely. If this escalates, expect capital flight from yen-denominated assets and a flight to safety in UK gilts. That might boost the pound temporarily, but it’s a fragile gain built on someone else’s misfortune.
In short, the ambassador is right to speak out. In the high-stakes game of international trade, every word counts. And in this case, words about cartoons could cost us real money.
