Online Grocery in Japan: Amazon Fresh, Rakuten Seiyu, COOP, Oisix

Online grocery Japan runs through net super storefronts and weekly co-op drops rather than one national shop.¹² The four anchors cover different needs, so most households combine a weekly routine with on-demand spot orders.

Procedures, fees, and requirements can change. Confirm current details at Amazon Japan, Rakuten Mart, your local COOP federation, Oisix, Aeon Net Super, and Ito-Yokado Net Super pages.

Overview

This guide compares Amazon Fresh with partner net supers, Rakuten Mart with Seiyu Netsuper, regional COOP delivery, Oisix, and the Aeon and Ito-Yokado supermarket apps.¹³²⁴ It applies to any resident ordering food and daily goods online, with coverage and fees set per service area and per store rather than nationwide.¹³

The pattern is consistent: enter a postcode to see which stores serve you, then compare the fee and minimum on that store page before ordering.¹⁵ Rural shoppers should check coverage first, since metro Tokyo has the widest choice.¹³

The landscape at a glance

Amazon Fresh suits fast on-demand orders in metro areas, Rakuten Mart suits planned domestic supermarket shops, COOP suits a fixed weekly household routine, and Oisix suits organic produce plus kit meals.¹³²⁴ Aeon and Ito-Yokado apps fill gaps with store-based same-day delivery.⁵⁶

Check your postcode on each service before comparing fees

Coverage differs by partner and store, so a fee comparison only makes sense after each postcode checker confirms you are served.¹²

Amazon Fresh direct covers Tokyo, Kanagawa, Chiba, and specific areas in Saitama (as of 2026-09; confirm current figures with Amazon Japan).¹ Its stated range is about 17,000 items from fresh vegetables, meat, and seafood to beverages, rice, baby food, and daily goods (as of 2026-09).¹

Partner net supers on the same Amazon storefront include LIFE, Valor, Seijo Ishii, ARCS, Marukyo, Itochain, Aruk, and SAN-A, each with its own coverage (as of 2026-09).¹ LIFE covers Tokyo, Kanagawa, Chiba, Saitama, Osaka, Hyogo, and specific areas in Kyoto (as of 2026-09).¹ Seijo Ishii lists about 4,500 store items including buyer-selected produce and in-store prepared foods (as of 2026-09).¹

Rakuten Mart listed about 14,000 items at launch across fresh, dairy, frozen, refrigerated, and daily goods (as of 2024-08).³ Launch areas were Tokyo, Kanagawa, Chiba, Saitama, Osaka, Hyogo, and Kyoto (as of 2024-08).³

Order pattern snapshot

Amazon net super delivers in as little as about 2 hours with 2-hour slot selection.¹ Rakuten Mart delivers same-day from dedicated fulfillment centers in six slots from 10 a.m. to 10 p.m., bookable up to 3 days ahead (as of 2024-08; confirm current figures with Rakuten Mart).³

COOP delivery runs once a week on a fixed member day ordered from a paper catalog or net catalog.²⁷ Oisix regular-box delivery runs weekly or biweekly on a member-set day with skip by 10 a.m. on the order deadline.⁸ Aeon Net Super ships from the nearby assigned store after postcode lookup.⁵

Amazon Fresh

Amazon Online Supermarket is area-limited, so the shopper enters a postcode to see usable stores.¹ Amazon members use net super with no extra registration or membership fee, and each store picks goods for Amazon logistics.¹

Coverage, time slots, and Prime requirement

Amazon Fresh direct delivery windows run 8 a.m. to midnight in 2-hour slots, with some areas 7 a.m. to 11 p.m. (as of 2026-09; confirm current figures with Amazon Japan).¹ Minimum delivery time is about 2 hours.¹

Net super items and regular Amazon items ship separately and cannot be combined.¹ Orders can use Amazon Points and gift cards at payment selection.¹

Missed Amazon net super deliveries are not redelivered

If nobody is present at the slot, the order is taken back and refunded, and locker or unattended drop is not accepted. Book a slot when someone will be home.¹

Assortment and foreign-brand fit

Amazon Fresh direct spans fresh vegetables, meat, seafood, beverages, alcohol, rice, baby food, and daily goods with frequent bargains.¹ Premium breadth on the same storefront comes via Seijo Ishii, with about 4,500 store items including buyer-selected produce, seafood, meat, and prepared foods (as of 2026-09; confirm current figures with Amazon Japan).¹

Foreign-brand breadth is an assortment inference from that Seijo Ishii positioning plus the Amazon cross-ship range, not a stated foreign-brand count. Urban shoppers with imported-food needs get the strongest fit in this set from Amazon Fresh direct plus Seijo Ishii on Amazon.¹

Rakuten Seiyu Net Super and Rakuten Mart

Old guides say Rakuten Seiyu Netsuper, while current pages say Rakuten Mart for the Rakuten side and Seiyu Netsuper for the Seiyu store side. The history below explains the split so stale links do not confuse you.³⁹

From joint venture to two services

Rakuten and Seiyu set up Rakuten Seiyu Netsuper as a joint venture in April 2018.⁹ On December 20, 2023 the venture became a wholly owned Rakuten subsidiary, with Rakuten keeping fulfillment-center delivery while Seiyu moved to store-shipped online supermarket.⁹

On August 8, 2024 the company became Rakuten Mart, Inc. and on September 25, 2024 the service launched as Rakuten Mart, while the Seiyu store-shipped service became Seiyu Netsuper.³ Existing site and app users kept the same UI and accounts with no re-registration at rebrand.³

Coverage, assortment, and Rakuten Points

The pre-split network reached 17 prefectures, namely Hokkaido, Miyagi, Fukushima, Chiba, Saitama, Tokyo, Kanagawa, Nagano, Aichi, Shiga, Kyoto, Nara, Hyogo, Osaka, Fukuoka, Kumamoto, and Nagasaki, with 3 fulfillment centers at Yokohama Kohoku, Ibaraki in Osaka, and Matsudo in Chiba (as of 2023-12; confirm current figures with Rakuten Group).⁹

The Rakuten Mart launch footprint targeted about 12 million households in metro Tokyo and Kansai from the Kohoku, Matsudo, and Ibaraki warehouses (as of 2024-08).³ Centers run frozen, chilled, and room-temperature control with about 70,000 orders per day processing capacity across served regions (as of 2024-08).³

Rakuten Mart delivery fee is 330 yen tax included, free over 3,500 yen tax included, with area variance (as of 2024-08).³ Maximum order is 45,000 yen tax included, paid by one-time credit card, Rakuten Points, or invoice (as of 2024-08).³ Rakuten ID linkage lets shoppers earn and use Rakuten Points on orders.¹⁰

COOP delivery

COOP delivery, or 生協 (seikyō, "consumer cooperative"), is the consumer-cooperative home delivery anchor that has run for decades through regional federations.²¹¹ The official portal maps each postcode to its local co-op, since assortment and terms differ by federation.²

Membership and weekly order pattern

Joining the local co-op comes first, with a flow of search, request materials, join, and start.² Ordering runs weekly from a paper catalog or net catalog, for example Co-op Deli e-friends net order.²⁷

Delivery runs once a week on a fixed member day, left at the door in cooler or cardboard boxes if absent.⁷ The portal states no minimum order amount with delivery-fee discounts available.²

Co-op Mirai covering Tokyo, Chiba, and Saitama lists a 500 yen entry share refunded on exit, while other federations list 500 to 1,000 yen by area (as of 2025-09; confirm current figures with your local co-op).⁷ A delivery fee can apply even in a no-order week unless a baby or child-rearing discount applies (as of 2025-09).⁷

Coverage by federation and family fit

COOP federations are regional, and the Co-op Deli group covers Tokyo, Chiba, Saitama, Tochigi, Gunma, Ibaraki, Niigata, and Nagano, with Co-op Mirai covering Tokyo, Chiba, and Saitama (as of 2025-09; confirm current figures with Co-op Deli).⁷ National scale reference lists over 300 consumer co-ops and about 30 million members in Japan.⁷

Catalog volume is high, with weekly paper catalogs that members can ask to reduce while some catalogs continue.⁷ Meal-kit and baby-food lines, including the kirakira baby range, support family weekly routines.⁷

Term	Reading and meaning
生協	生協 (seikyō, "consumer cooperative, COOP")2
ネットスーパー	ネットスーパー (netto sūpā, "net super, online supermarket")1
定期ボックス	定期ボックス (teiki bokkusu, "regular box, recurring weekly box")8

Oisix

Oisix main store sells selected foods for daily meals on a regular basis, including organic, specially cultivated, minimum-additive processed food, and time-saving meal kits.⁴ Its stated motive is food that parents feel safe feeding children.⁴

Organic range and Kit Oisix

Kit Oisix (kitto oishikkusu, "Kit Oisix meal kit") kits bundle a main plus side or soup for 2 or 3 people with recipe cards.⁸ The floor starts from 994 yen for 2 persons and from 1,566 yen for 3 persons (as of 2026-04; confirm current figures with Oisix).⁸

Secondary reporting cites over 200 million cumulative Kit Oisix meals, but practitioner sources describe the count inconsistently so treat it as an indicator rather than a settled census (as of 2026-02).⁸ The group also runs Daichi wo Mamorukai and Radish Boya alongside the Oisix main store.⁴

Membership, pricing, and delivery rhythm

There is no enrollment, annual, or cancellation fee, frequency is member-chosen, and cancel by deadline carries no cancel fee.⁸ Regular-box shipping for Honshu members is tiered by order value in bands from free at higher totals down through 200 to 1,000 yen bands below (as of 2026-04; confirm current figures with Oisix).⁸

Chilled and frozen goods in one order incur one shipping charge, but frozen inclusion adds a separate frozen handling fee.⁸ A first-time-household trial set is offered in rotating campaigns, with secondary reporting at 2,980 yen for an 11,500 yen value with free shipping and one per household (as of 2026-06).⁸

Regular-box carts auto-add suggested items each week, so members must remove or skip before the deadline.¹² Skip closes at 10 a.m. on the order deadline.⁸

Regional supermarket apps

Store-based apps work as the spot-fill layer beside a weekly anchor. Terms are set per store and area, so the assigned-store page outranks any general guide.⁵⁶

Aeon Net Super

Aeon Net Super delivers from the nearby assigned store, found by postcode search.⁵ Ordering requires member login through iAEON ID.⁵ Store pickup where offered avoids delivery fees.⁵

Fees and free-shipping thresholds are set per store and area. One store-scoped example pattern is 550 yen at 1,999 yen or less, 330 yen at 2,000 to 9,999 yen, and 165 yen at 10,000 yen or more (as of 2026-09; confirm current figures with your assigned Aeon store).⁵

Ito-Yokado Net Super by ONIGO

Legacy Ito-Yokado Net Super ended in February 2025, and the current service is Ito-Yokado Net Super by ONIGO with ONIGO, founded June 10, 2021, as operator.⁶ Delivery hours are 10 a.m. to 9 p.m. except year-end and New Year, with same-day possible within hours (as of 2026-09; confirm current figures with Ito-Yokado Net Super).⁶

There is no minimum order amount, but a small-order surcharge applies under 7,000 yen as detailed in the fee table (as of 2026-09).⁶ Registration with address and email plus mail or SMS auth is required, with payment by credit card, Apple Pay, Google Pay, debit, prepaid, d払い, or cash where area-supported.⁶

Ito-Yokado charges delivery plus a small-order add-on

Delivery and small-order fees stack below the thresholds, so a small basket can carry two charges at once. Consolidate orders past 7,000 yen and 12,000 yen where possible.⁶

Delivery fees and minimum orders

The cross-service pattern is a 300 to 550 yen delivery fee band with free shipping above a 3,500 to 12,000 yen threshold set per service and area (as of 2026-09; confirm current figures with each store page).³⁶ Small-order surcharges are the Ito-Yokado-specific layer from 110 to 440 yen under 7,000 yen (as of 2026-09).⁶ Oisix and COOP use order-value shipping tiers rather than a single flat fee (as of 2026-04).⁸⁷

Service	Delivery fee	Free threshold	As of	Notes
Rakuten Mart	330 yen	3,500 yen	2024-083	Tax included; varies by area
Ito-Yokado by ONIGO delivery	330 to 490 yen	12,000 yen	2026-096	Time-slot discounts possible
Ito-Yokado by ONIGO small-order add-on	0 to 440 yen	7,000 yen	2026-096	Stacks with delivery fee
Oisix Honshu regular	0 to 1,000 yen pattern	Higher bands free	2026-048	Plus frozen handling where frozen included
Co-op Deli entry share	500 to 1,000 yen refundable	n/a	2025-097	One-time share, not a fee

Figures in the table carry currency in the As of column. The pattern above held across fetched pages (as of 2026-09).³⁶

How to read your store page

Amazon postcode check, Rakuten Mart area page, COOP postcode search, Aeon store assignment, and the Ito-Yokado store list are the authoritative coverage checks.¹³²⁵⁶ Fees may vary in some areas even inside one brand.³

Priority delivery on Ito-Yokado adds 220 yen where selected (as of 2026-09).⁶ Maximum order on Rakuten Mart is 45,000 yen tax included (as of 2024-08).³

Choosing a strategy as a foreign resident

The choice turns on where you live and what you cook. Urban shoppers optimize for speed and imports, while families and rural shoppers optimize for routine and coverage.

The diagram above traces the decision this section describes. Each branch cites its source in the surrounding prose rather than inside the block.

Urban Tokyo with foreign-brand needs

Amazon Fresh direct plus Seijo Ishii on Amazon gives the strongest urban-Tokyo foreign-brand breadth in this set.¹ Supermarket apps such as Aeon and Ito-Yokado work as same-day spot fills alongside a weekly anchor.⁵⁶

Checkout across these services is Japanese-first, and a browser translation extension plus one assisted first order is the usual bridge in resident reporting.¹³

Families and rural areas

COOP weekly routine fits families with children through stable produce pricing, baby-food lines, and meal kits.⁷ Oisix fits time-pressed households wanting organic produce and kit meals with skippable weekly rhythm.⁴⁸

Rural shoppers face thinner Amazon Fresh and Rakuten Mart footprints and should check the postcode tool first, then fall back to COOP plus the local supermarket app.¹³² Physical stores remain the pick for judging fresh vegetables and meat visually, while online covers the heavy and routine remainder.¹³

Good to know

The Rakuten Seiyu name still appears on old guides

Guides dated before late 2024 say Rakuten Seiyu Netsuper, while since September 25, 2024 the Rakuten side is Rakuten Mart and the Seiyu side is Seiyu Netsuper.³ Check the date on any guide before following its links, since old URLs and app names may redirect or split.³

COOP delivery day is fixed and easy to miss

Missing the weekly order deadline pushes the shop to next week, since delivery runs once weekly on a fixed day.⁷ Set a phone reminder for the deadline day and keep one supermarket app ready for gaps.⁷

Oisix auto-adds to the regular box

Oisix adds suggested items to the regular box each week, and unremoved items order automatically at the deadline.¹² Review the cart weekly or skip the week by 10 a.m. on the deadline when the fridge is full.⁸

Japanese-language checkout is still the norm

Tokyo-area ordering guides report Japanese-only checkout across most grocery delivery sites.¹³ A browser translation extension plus one assisted first order is the usual bridge, and product reviews in the app help after setup.¹³⁷
