What It Is

IOSYS（イオシス） is a Japanese e-commerce retailer for used smartphones, tablets, and PCs, with the site promoting the slogan “けっこう安い” (“pretty cheap”). Based on the crawled content, its main product categories include iPhone, Android devices, SIMフリースマホ, iPad, Surface, Windows tablets, Apple Watch, MacBook, laptops, and desktop PCs, covering unused items, used A/B/C-rank products, outlet items, and junk items.

Core Strengths and Product Selection

The platform provides fairly detailed descriptions for second-hand electronics. Listings show storage capacity, SIM card specifications, carrier version/SIMフリー status, included accessories, stock quantity, release date, condition grade, and whether there is a network usage restriction marked ▲. Its filtering options are also comprehensive: buyers can search by brand, carrier, features, SIM size, color, price, release date, CPU, OS, memory, storage capacity, and more. This makes it suitable for buyers who already have a specific model and budget in mind. Its editorial features also note that used iPhone prices fluctuate with Japan’s new-life season, new product launches, inventory levels, and buyback volume, which can be useful when deciding when to purchase.

Pricing, Payment, and Fulfillment

IOSYS uses retail pricing, with prices displayed in Japanese yen including tax. Standard nationwide shipping in Japan starts from 640 yen, with an additional 330 yen charged when the order includes a PC or monitor. Delivery is generally handled by ヤマト運輸, while some products or regions are served by 佐川急便. Conditional same-day shipping is also supported. Payment options are broad, including credit cards, Amazon Pay, Paidy deferred payment, PayPay, cash on delivery, bank/postal transfer, and more.

After-Sales Support, Pros, and Cons

A key advantage is its relatively complete warranty system. If a device becomes 赤ロム due to network usage restrictions, it is covered regardless of the warranty period. Phones and tablets come with up to 6 months of warranty depending on grade; used iPhone, smartphones, iPad, and similar products include a 3-month free warranty; PCs come with a 3-month warranty; and extended warranty can also be purchased. Googleレビュー shows 9,520 reviews with a 4.7 rating, indicating a meaningful user base. The limitation is that the 7-day return policy applies only to members, web purchases, certain used iOS/Android products, items priced at 20,000 yen or more, and specified payment methods. Return shipping is borne by the customer, and new, unused, and outlet products are not eligible.

Who It’s For and Access from China

IOSYS is well suited to users in Japan looking for used phones, tablets, and PCs with warranty coverage, as well as buyers researching second-hand electronics pricing in Japan. The text does not indicate overseas shipping or Chinese-language support, so users in China may face difficulties with receiving addresses, payment accounts, and after-sales returns. The site’s accessibility from China cannot be determined from the source text and is marked as unknown. Alternative options include Japanese channels such as じゃんぱら, ゲオ, ソフマップ中古, and Mercari.
