From power generation to discounts, companies in Japan work to reduce food waste
Akindo Sushiro, which runs conveyor-belt sushi chain Sushiro, and five other major restaurant operators have launched a project to produce methane gas from leftovers and food scraps as fuel for power generation.
Under the project, JFE Engineering is in charge of power generation and distribution, while the electricity can be purchased for a low price by participating companies, also including Royal Holdings, which operates Royal Host restaurants, and Duskin, the operator of the Mister Donut stores.
Meiji established a directly managed store called Meiji the Sutenai ("Don't throw things away") Factory in the city of Saitama at the end of last year, selling dairy products such as yoghurt whose best-before dates are approaching.
"The name of the store reflects our desire to not throw away products that can still be eaten," an official of the food maker said.
In the retail and food industries, there is a business practice known as the "one-third rule." For example, if a product has a three-week period from the date of manufacture to its best-before date, it must be delivered to retailers within the first week.
It has been pointed out that this is a factor behind the rise in food waste as products that have passed the deadline are subject to disposal.
Meiji's directly managed store, however, sells products that have passed the delivery deadline at about 40% off the suggested retail prices. They remain on store shelves until the best-before date.
The store was scheduled to close in April this year, but it stayed open due to its popularity.
Lawson is focusing on frozen onigiri rice balls and bread, which can be sold for a long time. The best-before date of frozen onigiri is about one year and that of frozen bread is about 200 days, contributing to reductions in food waste. Lawson's operator has increased the number of its convenience stores handling them since July 15.
Also, in July last year, Lawson extended the expiration dates of some regular onigiri products by six hours thanks to comprehensive hygiene management.

Japan's Meiji markets premium milk to China's urban moms
Meiji launched its Oishii Gyunyu milk brand in China on July 29. (Photo obtained by Nikkei) YUME NAMEKATA TOKYO -- Japan-based food company Meiji launched its popular Oishii Gyunyu milk brand in China on Tuesday, targeting affluent, health-conscious urbanites as it seeks to pull Chinese operations out of the red. The refrigerated product sells for about 30 yuan ($4.18) for a 900-milliliter container -- higher than both its usual cost in Japan and the roughly 20 to 25 yuan average price of milk in China. It is also more expensive than Meiji's current mainstay Chinese milk brand, priced at around 27 yuan.

Japan Releases Guidelines for IT Giants on Smartphone Apps
News from Japan Technology Jul 29, 2025 22:22 (JST) Tokyo, July 29 (Jiji Press)--The Japan Fair Trade Commission on Tuesday released guidelines for information technology giants, such as Google LLC and Apple Inc., regarding smartphone apps, ahead of the full implementation in December of a new law to promote competition in the app market. The guidelines prohibit these companies from using data obtained through their operating systems to develop products with competitive advantages and hampering the use of other companies' payment systems in apps. They are also urged to allow customers to choose from among multiple search engines when buying new devices. The law, which will take full effect on Dec.18, covers smartphones using the operating systems of Apple and Google and bans excluding other companies' app stores from the platforms. It also requires OS functions necessary for developing apps to be made openly available. To draw up the guidelines, the commission accepted public comments until June 13. Apple voiced concern that the law could force it to share confidential technology and user information with third parties. [Copyright The Jiji Press, Ltd.] Jiji Press

Who buys the F-150s, and more Japan deal mysteries
The long-awaited trade deal between the U.S. and Japan has investors celebrating after months of uncertainty. But as the song goes, nagging questions always remain. Who is going to buy the "cars, SUVs and trucks' that U.S. President Donald Trump has promised to sell? Who is going to purchase the 100 Boeing jets? And what possible structure could the $550 billion fund, allegedly financed by Tokyo with 90% of profits going to U.S., actually take? Answers are sorely needed, not just because of an already growing comprehension gap between the countries over what was actually agreed, but to inform South Korea, the European Union and other close U.S. allies who are trying to wrap up similar deals before Aug. 1. Let's start with autos, long the main source of Trump's dissatisfaction with Tokyo, as well as the largest single cause of the trade deficit. The White House fact sheet (if indeed it can so be called) declared that "long-standing restrictions on U.S. cars and trucks will be lifted, granting U.S. automakers access to the Japanese consumer market.' Of course, U.S. carmakers have enjoyed unlimited access to the Japanese market for decades. As I noted in April, the problem is that U.S. cars just aren't good enough for the local consumer — and Detroit largely isn't interested in trying to muscle its way into a hyper-competitive market dominated by domestic players. Tokyo can try making it a little easier to import U.S. vehicles, such as simplifying inspection procedures. But it can't rebuild cities to fit the bloated models U.S. automakers favor. Around 84% of streets in Japan are municipal roads with an average width of just 3.7 meters (about 12 feet). Even if Tokyo gave everyone a Ford F-150 pickup, its 2.4-meter width would prevent two from passing on narrow streets. Hence cute minivans and kei-cars dominate while, as my colleague Liam Denning said this week, "U.S. automakers do not, in general, make an adorable little anything.' In any case, Japan's auto market has been shrinking for years, with new cars sold down about 20% from a 1990s peak. Automakers constantly fret that young people are losing interest in learning to drive, while the growing numbers of elderly citizens are encouraged to return their licenses. But more significant is what form the $550 billion investment fund will take. Treasury Secretary Scott Bessent said that the "innovative financing mechanism' was the key to Tokyo getting a deal at all. But neither side seems to agree on what it looks like. The idea first surfaced in May when the Financial Times reported that SoftBank Group founder Masayoshi Son had suggested a joint sovereign wealth fund. The White House calls it an "investment vehicle' that will "rebuild and expand core American industries.' Prime Minister Shigeru Ishiba, however, refers to a combination of equity, loans and guarantees that will be led by the Japan Bank for International Cooperation and guarantees by Nippon Export and Investment Insurance. That sounds more like overseas development aid than a wealth fund — though few could argue American infrastructure might actually benefit from that. Trump now promises Japan will "give us 90% of $550 billion!' Tokyo is saying that applies to projects where 90% of investment is from the U.S. — in other words, profits are proportional. Does the figure include funding already pledged, such as SoftBank's promised $100 billion? Who knows?! Indeed, a leaked photo from the talks shows what looks like a proposal from Japan for a $400 billion fund, crossed out with $500 billion handwritten on top. That proposal also suggested a 50% profit share. Is this just repackaged existing spending into a simple PowerPoint slide? After all, Japan already invested $783 billion in the U.S. in 2023 and Ishiba pledged in January to boost that to $1 trillion in the future. The problem is that at some stage, this needs to be worked into actual policies. And this is where Ishiba's rush to agreement might come back to bite, especially if he's no longer in the job when the talks get down to details — something that, despite his denials, still seems all but certain after the drubbing his Liberal Democratic Party took in recent Upper House elections. There are plenty of parts of the deal that do make sense. The 100 Boeings can find a home at the country's airlines, though Japan has admitted the number includes at least some already-planned purchases. As the world's largest buyer of liquid natural gas, Tokyo's participation in the Alaska project always seemed logical. Even if the two sides don't seem to agree on what they decided on defense, Japan needs to spend more and the U.S. is the logical seller. Above all, it's encouraging to see the White House, after all these months of tense relations, again describe its ally as the "cornerstone of peace in the Indo-Pacific.' But with all these questions — and Washington continuing to hold the threat over Japan's head with a quarterly evaluation of its compliance with the deal — the market's sigh of relief might still be premature.
