On 15 September 2026, the Cabinet approved an outline that includes temporarily cutting the consumption tax on food to 1% for two years from April 2027. Food has been taxed at 8% since October 2019 (the standard rate is 10%).
Japan's inflation rate was between 2.5% and 3.3% in every year from 2022 to 2025.
Over the year from August 2025 to August 2026, international prices rose by about 43% for wheat (US) and about 33% for Brent crude, and rice (Thai) and maize also rose.

In 2024, about 39% each of Japan's wheat imports came from Canada and the United States, and about 77% of its maize imports came from the United States.
Real household consumption per person grew by only about 0.7% from 2019 to 2024. In 2025 there were about 0.67 million births and about 0.49 million marriages.
With inflation above 2% for four years in a row and real household consumption per person barely growing, there is a case for easing the cost of food. However, a uniform tax cut gives larger savings to higher-income households, and benefits targeted at families with children and young people would probably do more, for the same money, to influence decisions about marriage and childbirth. A temporary cut should also be designed with the price jump at its end in mind.
If the tax cut is passed on to shelf prices, food prices would fall in 2027 and inflation could come in below the 3.2% of 2025 (the materials contain no data on food's weight in overall prices or on how much of the cut reaches prices, so this step is conjecture). If the rate goes back up when the two-year temporary measure ends, prices could jump back at that point (the materials do not give the rate after two years, so its return is an assumption).
If international prices of wheat, rice, maize and crude oil keep rising, prices of imported food could rise and offset the tax cut. In that case, inflation in 2027 may not fall much from the 3.2% of 2025 (the materials contain no data on how much or how quickly international prices pass through to Japanese retail prices, so the extent of the offset is conjecture).
In either scenario, this data shows no clear channel through which a two-year temporary tax cut would substantially change decisions about marriage or childbirth (conjecture). Births fell from about 0.98 million in 2016 to about 0.67 million in 2025, and are likely to keep falling in 2027.
Another view holds that food takes up a larger share of spending in lower-income households, so a tax cut on food effectively helps them most, and reaches everyone quickly, which makes it better than targeted benefits. Building a targeted scheme takes time and administrative cost, so while prices are rising, a uniform tax cut is the more practical option.
