The proposal to lower Japan's food consumption tax has highlighted several problems facing Prime Minister Sanae Takaichi and her administration. One major issue is technical. Retailers and system companies say it could take around a year to update cash registers, payment systems, and accounting software to handle a full 0% tax rate on food. Because of that, the government is now leaning towards a temporary 1% rate instead, which would be easier to introduce quickly.
There are also concerns over cost. Cutting the food tax would reduce government revenue by trillions of yen at a time when Japan already faces heavy public debt and pressure over its finances.
Politically, the move is awkward for the ruling Liberal Democratic Party, which had promised during the election campaign to push for a zero-per-cent food tax. Moving to 1% instead risks criticism that the government is backing away from a key pledge.
Officials are also worried about what happens later. Even if the reduced tax only lasts two years, raising it back to 8% afterwards could prove politically difficult once consumers become used to lower prices.
