Tokyo stops subsidising panels that are roughly 72% Chinese-made

Multiply the two import shares Japan's own reporting supplies and roughly 72% of the panels in service there came off Chinese lines ^[10], which means a subsidy paid against a panel's purchase price was routing close to that fraction of every yen into Chinese manufacturing. Withdrawing a payment costs a government nothing, requires no border machinery, and gives nobody a tariff to file against.

Two Japanese outlets describe the same budget line differently, and the difference is testable. FNN reports the Environment Ministry reasoning that panel prices have kept falling, so installation no longer needs state help ^[7]; the Yomiuri Shimbun reports the measure as aimed at purchase subsidies for silicon panels, where Chinese products hold a large share ^[8]. If module prices turn up next year and the subsidy stays gone, the Yomiuri was describing the policy and FNN was describing the explanation.

The replacement demand is being funded ahead of the supply that would serve it. Next year's perovskite adoption budget is four times this year's ^[11], while METI's stated ambition, announced last July, is annual mass production at one gigawatt by 2030 ^[16], so buyers get money now for cells whose domestic volume is a decade-end milestone. The design bias toward thin, light film for building walls and rooftops ^[17] suggests the ministry is buying surface area silicon cannot reach rather than trying to win on cost per watt. The raw-material position is the part I would underwrite: the USGS puts Japan's iodine reserves near 4.9 million tons against about 750,000 tons for Chile, the top producer ^[13], roughly six and a half times as much ^[14], and Japan is only the world's number two producer of the stuff ^[12], which is a gap between what sits in the ground and what gets pulled out of it, and gaps like that are capex problems rather than geology ones.

Washington's instrument works the other side of the same objective. The grid emergency order signed on the 26th screens imports of transformers, high-voltage circuit breakers, inverters, battery storage, generators and industrial control systems for national security threat ^[5], with the perimeter drawn at bulk power systems including transmission at 69 kV and above ^[4]. Screening adds no domestic factory, so the near-term burden falls on whoever has already signed for a substation or a storage block and now carries a customs outcome inside a fixed price.

This is probably wrong, but the more durable version of the story is that both capitals have concluded the purchase order clears faster than the tariff schedule, and since the American order rests on IEEPA and the National Emergencies Act, the same authority behind the reciprocal tariffs ^[3], it can be unwound by the signature that made it. The counter-thesis belongs in the same breath: if FNN's account is the real one, Japan simply stopped paying for something that got cheap by itself ^[7], and the perovskite money is ordinary industrial policy dressed up by proximity to an American order. What would break my read is Chinese-made perovskite qualifying for Tokyo's adoption support, or a first year of screening that clears Chinese transformers on paperwork and a short wait. Then the whole apparatus prices as a filing fee.
