Grocery delivery services bring you organic vegetables and processed foods with fewer additives. You may be curious, but it is hard to tell “which one to choose” and “how much it will really cost if I keep using it.”

This article compares five representative services that promote additive-free and low-pesticide food:

Oisix (オイシックス)
Radish Boya (らでぃっしゅぼーや)
Daichi o Mamoru Kai (大地を守る会)
Palsystem (パルシステム) (consumer co-op)
Seikatsu Club (生活クラブ) (consumer co-op)

The comparison uses only information on each company’s official pages. Trial set terms, ongoing costs, and the standards for produce and processed foods are set out in tables.

Bottom line: comparing through a “trial set” first is the surest way

The three private companies (Oisix, Radish Boya, Daichi o Mamoru Kai) each offer a trial set for 1,980 yen (tax included, free shipping). All are a single delivery and do not automatically turn into a subscription. All three have a full-refund guarantee with conditions
The co-op Palsystem has a trial set for 980 yen (tax included, free shipping). However, it is available only in 12 prefectures, including Tokyo and Kanagawa
For Seikatsu Club, start with a free information request. Depending on the region, there are trial perks for people who request information
When you keep using a service, private companies charge “annual fees and shipping,” while co-ops charge “a capital contribution (refunded when you leave) and a weekly fee.” Whether you pay in weeks when you place no order differs by service
Each company publishes its standards for pesticides on produce and additives in processed foods. Some give numbers, such as Seikatsu Club limiting permitted additives to 93 items

Quick guide: who each service may suit

*“Who it may suit” is Urayomi’s own summary based on the services described on each company’s official pages.

Oisix	Organic JAS certified cultivation, or chemically synthesized pesticides and chemical fertilizers at 50% or less of conventional farming in the area	Does not handle foods made with synthetic preservatives or synthetic colorings. Publishes additives in three groups: “allowed,” “use as little as possible,” and “not used”
Radish Boya	Its own standard, “RADIX.” Bans 120 ingredients among the pesticides the government permits. Handles only produce that meets standards equivalent to organic JAS or specially cultivated produce	“If it can be made without, don’t use it.” When used, limited to designated ones
Daichi o Mamoru Kai	Cultivation that does not rely on pesticides or chemical fertilizers. In addition to its own standards, audited by a third-party certification body following organic JAS audit methods	Food additives and genetically modified ingredients are, in principle, not used
Palsystem	Its own cultivation standards. “Core Food” is organic JAS certified; “Eco Challenge” uses chemically synthesized pesticides and chemical fertilizers at 1/2 or less of conventional farming	Of the roughly 1,500 or more substances approved as additives in Japan, about 20% are not used in making products
Seikatsu Club	Uses chemically synthesized pesticides and chemical fertilizers as little as possible. Its own residual pesticide standard aims for 1/10 or less of the national standard	Of the 803 items (excluding natural flavorings and general food additives), only 93 (about 1/8) are permitted

(Each company’s official pages)

How standards are written differs by company. Wording like “X or less,” “in principle not used,” or “use as little as possible” may not mean zero. To find out what is used in each product, check the ingredient list (原材料名) on each company’s product page.

For Japan’s “organic JAS” and “specially cultivated” rules and how to read pesticides on vegetables, see the Oisix article and the vegetables and pesticides database. For the rules on “additive-free” (無添加) and “not used” (不使用) labeling, see the article on “additive-free” labeling rules.

If you want vegetables delivered from farmers or small greengrocers

If you don’t need processed foods and only want vegetables delivered, there are also greengrocers that deliver vegetable sets and farm-direct mail-order services where you can buy directly from farmers.

How to get started

Check the contents and ease of use with a trial set or an information request: The trial sets of the three private companies do not automatically become subscriptions, so you can compare before deciding
If you continue, check the subscription deadline and the “cost for weeks with no order”: Some services confirm your order if you do nothing, and some charge a fee even in weeks with no order
Families with small children should not forget to apply for perks: Many of the perks that make delivery fees or other fees 0 yen require an application

Frequently asked questions

Q. Can I buy only the trial set and not subscribe? A. The trial sets from Oisix, Radish Boya, and Daichi o Mamoru Kai are a single delivery and do not automatically become a subscription. A subscription is a separate sign-up (each company’s sign-up page).

Q. Can I order the trial set as many times as I like? A. All are for first-time customers, once per household (Radish Boya: once for first-time customers).

Q. Is a co-op’s “capital contribution” (出資金) returned? A. For both Palsystem and Seikatsu Club, it is refunded when you leave (withdraw from) the co-op.

Q. Is additive-free food good for your body? A. Urayomi does not write that. Food additives that the government has approved have gone through safety evaluation. Each company’s standards show “what is not used” and are material for choosing. For details, see the article on “additive-free” labeling rules.

Urayomi’s approach

Grocery delivery services differ considerably in both how they think about standards and how costs add up when you keep using them. Urayomi does not write which one is “safe” or “the best.” We value lining up the standards and prices each company publishes so that you can use them as material for choosing.

If you are unsure, we recommend first comparing the actual contents with a trial set that does not automatically become a subscription.
