Seven-Eleven, Lawson, and FamilyMart unveil September "Tsukimi" sweets

On September 1, 2026, Japan’s major convenience store chains simultaneously released new dessert lines themed around tsukimi (moon-viewing), marking the transition from summer to autumn. Seven-Eleven introduced an "Otsukimi Pudding Crepe," while Lawson launched a "Moon-viewing Custard Pudding Tart," both featuring egg-yolk-colored creams designed to resemble the full moon. These launches follow the standard Tuesday release schedule for new konbini products, aiming to capture early autumn consumer interest before mid-month promotions.

Frozen bento delivery market expands with subscription services

The market for frozen "bento" meals—ready-made main and side dishes served on a single plate—is seeing significant growth in Japan, driven by subscription-based home delivery services. As of late August 2026, these services are gaining traction among households seeking convenient, microwaveable options that maintain the aesthetic and nutritional balance of traditional bento boxes. This trend reflects a shift in home cooking habits, where convenience is increasingly prioritized without sacrificing the visual appeal of Japanese lunchboxes.

7-Eleven Hawaiʻi launches authentic "Tamago Sando"

On September 1, 2026, 7-Eleven Hawaiʻi began selling a Japanese-style egg salad sandwich known as "tamago sando," featuring locally baked Shokupan bread. This move extends the global popularity of Japanese konbini staples, bringing the "pillowy bread and creamy egg salad" experience to US consumers. The launch underscores the international branding power of Japanese convenience store food culture, which has become a significant export of soft power.

Local view

Local media outlets are highlighting the dichotomy between premium new product launches and the severe cost-of-living crisis affecting household budgets. The Shokuhin Shimbun (Food Newspaper) reported on September 2 that the packaged rice market is at a turning point, with 2026 harvest rice prices beginning to fall but retail costs remaining high due to processing and packaging expenses. Meanwhile, TV Asahi noted that the sheer volume of price hikes this month is forcing consumers to reconsider their shopping habits, with many shifting toward cheaper private-label brands and bulk purchases.

Context & numbers

• Record Price Hikes: In September 2026, 4,923 food and beverage items in Japan are set to rise in price, the highest number for a single month in over three years. This represents a more than threefold increase compared to the same period last year.
• Major Manufacturers: Kewpie announced on September 1 that it will raise prices on 224 products, including mayonnaise, starting November 1, citing rising costs of packaging materials and edible oils.
• Household Impact: The surge in prices is impacting daily life significantly; for example, the price of a popular "Shumai Bento" (pork dumpling lunchbox) has risen from approximately ¥680–690 to ¥1,180, reflecting broader inflation trends.

On the radar

• September 8 New Releases: Seven-Eleven has listed new products for release starting September 8, including a large-sized rice ball with fried chicken mayonnaise (Karaage Mayonaise) priced at ¥289 (tax included), signaling continued innovation in the onigiri category despite inflation.
• FamilyMart Stationery: FamilyMart continues to roll out its "Konbini Wear" stationery line, co-developed with designer Hiroshi Ochiai and Kokuyo, expanding beyond food into lifestyle goods.
