Amazon Japan announced on May 19, 2026 that it has partnered with San-A (headquartered in Ginowan), Okinawa Prefecture's largest retailer, to launch "San-A Online Supermarket on Amazon.co.jp," a new online grocery service offering San-A's products through Amazon[1][2]. Leveraging Amazon's delivery network, the service covers 13 municipalities including Naha and delivers orders in as little as two hours[1][2]. San-A becomes the eighth partner supermarket brand on Amazon's online grocery platform, and the launch marks the first time Amazon's online grocery service is available in Okinawa[1].

Thousands of Items From San-A Stores, Two Delivery Time Slots

The new service handles thousands of items sold at the Okinawa-based supermarket San-A, including fresh vegetables, meat, rice, frozen foods, and private brand goods[1]. Amazon handles the delivery, and there is no minimum order requirement[1].

Delivery is offered in two time slots — 12:00–14:00 and 16:00–18:00 — and customers can choose a two-hour window on the same day, the next day, or the day after that[1]. By paying an additional shipping fee of 300 yen (290 yen for orders of 8,000 yen or more), customers can also specify a one-hour delivery window[1]. The service is accessible through the Amazon shopping app and through the dedicated URL "amazon.co.jp/sana" for both PC and mobile[1].

Standard delivery fees for Prime members are free for orders of 8,000 yen or more, 290 yen for orders between 3,000 and 8,000 yen, and 590 yen for orders under 3,000 yen[1]. For non-Prime customers, the same tiers cost 200 yen, 490 yen, and 790 yen respectively[1].

Coverage Spans 13 Municipalities, Centered on Central and Southern Main Island

The service area covers six cities — Naha, Ginowan, Urasoe, Okinawa, Tomigusuku, and Uruma — plus parts of Kunigami District (Onna Village and Kin Town), Nakagami District (Chatan Town, Kitanakagusuku Village, Nakagusuku Village, and Nishihara Town), and Shimajiri District (Haebaru Town), for a total of 13 municipalities[1][2]. Some areas within each municipality are excluded, with the listed scope reflecting the coverage as of the launch date[1].

The coverage spans the major population centers of central and southern Okinawa's main island, including San-A's home base of Ginowan, and reaches as far north as Onna Village on the way toward northern Okinawa[1][2]. Amazon has indicated that the service area will expand gradually, but for now the outer islands such as Miyako and Yaeyama are not covered[1].

San-A Expands Sales Channels, Has Operated Its Own Online Grocery Since 2014

San-A has operated its own delivery-based online supermarket since 2014, and the new collaboration with Amazon supplements that existing service to broaden the company's sales channels[2]. As the largest supermarket chain in Okinawa Prefecture, San-A is combining the online retail know-how it has built in-house with Amazon's delivery network[2].

For Amazon, the company has so far run its own Amazon Fresh service alongside seven partner supermarkets — Life, Valor, Seijo Ishii, Arcs, Marukyo, Ito Chain, and Aluk — covering the Kanto, Kansai, Aichi, Hokkaido, Fukuoka, Miyagi, and Hiroshima regions[1]. With San-A joining the lineup, Okinawa is added to the coverage map, and Amazon's online grocery now has eight regional partner brands[1].

Summary

On May 19, 2026, Amazon Japan partnered with San-A, Okinawa's largest retailer, to launch "San-A Online Supermarket on Amazon.co.jp"[1][2]. The service delivers thousands of items, including fresh produce, to 13 municipalities in central and southern Okinawa main island in as little as two hours with no minimum order, offering two delivery slots from 12:00–14:00 and 16:00–18:00[1]. San-A is the eighth partner store in Amazon's online grocery lineup and the first to bring the service to Okinawa[1].
