What nairu is

nairu (ナイル) is a Japanese-language online shop for physical adult video: new DVDs, used DVDs and disc-only items. Its masthead tag calls it the official site of Tone Shoten (利根書店), and its terms name the operator of the shopping site as 株式会社プリマベーラ (Primavera), with an address in Ota, Gunma. The site's own description adds that Tone Shoten runs more than 30 shops in northern Kanto and that the web shop stocks popular titles alongside niche ones other mail-order sites lack. The pages mention no streaming and no downloads; the store ships discs. Every page, the interface and the help included, is in Japanese, and the terms limit delivery to addresses in Japan, which matters more than anything else for a reader outside the country.

What it carries and how it is organized

The site is split into three catalogs that sit side by side in the top menu: new DVDs, used DVDs, and disc-only items. Around them the shop offers a ranking page, a performer list, a store list, a goods shelf, a user guide, an FAQ, news and campaigns, store blogs and a member area. The home page also speaks of listing stores: it advertises newly listed used items and carries notices and blog posts from the stores that list them. The pages do not spell out how that arrangement works.

Titles can be reached by list or by tag. The product list can be sorted by sales, by rating and by number of favorites, and by date through new arrivals, today's arrivals, preorders, the latest releases and semi-new releases. The tag menu is large. A popular-genres block and a full genre list sit first, followed by separate lists for situation, performer type, costume and play. The genre list itself includes high-definition titles, titles of four hours or longer, 10-disc sets, best-of and compilation releases, performer best-of sets, concept titles, drama, debut releases, viewer-submission titles, indie releases, adult cinema, titles for women, 3D and VR-only titles, and a Blu-ray tag. It also lists imported Western films. The situation, type, costume and play lists carry long runs of tags, mature and amateur titles, cosplay, massage and lesbian titles among them, which makes the shop closer to a search index than to a hand-picked shelf. A goods shelf sits beside the discs, and the genre list also tags photo books, comic volumes and anime, which the page presents as part of one retail catalog and not as separate stores.

There are two ways into the catalog by name. The performer list has a popular-performers block, which shows 月野りさ, 葵つかさ and 沖田杏梨 at the head, and a top-10 ranking block. The maker list is paged and searchable and shows Latin-script names such as GENEKI, Get Some Action, Ken World, Waffle and WIFE next to many names written in Japanese, with VR makers such as KMPVR among them. A popular-makers block on the home page names ROCKET and S級素人 among its entries. The shop is a retailer for many makers and not a studio or a membership service.

The ranking pages are split by condition: one set for used DVDs and one for new DVDs, each with daily, weekly and monthly views. On the home page the used-DVD sales ranking opens with best-of titles, a new-arrivals block shows the latest used listings, some marked as outlet items, and a sale block shows items marked down. These pages describe what is selling; no catalog size is given.

A registered member gets a small account area. The member menu lists account information, purchase history, a favorites list and settings for restock notices, and the login page says registration is free.

Japan mechanics

The seller and its licensing are stated plainly. The operator page lists 株式会社プリマベーラ as the seller, at an address in Ota, Gunma, with a public email address and a phone line answered from 10:00 to 18:00. A separate notice under the used-goods trading law gives the dealer permit number 第421120000947号, issued by the Gunma Prefecture Public Safety Commission. Every page opens on an age prompt that refuses access to anyone under 18.

On language, the site is Japanese-only. The pages mention no English interface, no English support, and no subtitled releases. On region, the terms state that delivery destinations are limited to Japan. There is no overseas-shipping option on the pages, and no list of accepted countries. The terms are governed by Japanese law, with the Maebashi District Court named as the exclusive agreed court. This is a domestic Japanese shop, not an export storefront, and for a reader outside Japan its use is as a reference for what is sold and how the stock is organized.

On mosaic, the pages make no general statement. The only reference is one tag in the play list, ギリモザ, a label for titles with minimal mosaic, and nothing else on the pages says whether a given disc is censored.

Price, access and billing

The money buys physical goods delivered to the door. There is no subscription and no streaming, and registration is free. The terms are written for registered members; each person or company may hold one registration, and the shop may refuse an application. Prices are shown tax included. Orders are taken around the clock. Delivery is normally within 7 days of dispatch, not counting weekends and holidays, and the contract is formed when the shop sends its dispatch email, not when the order is placed. The order confirmation email stands in for a sales slip.

Three payment routes are described. Credit card requires a card in the customer's own name, in a single payment with no installments or revolving plans, and the charge is taken when shipping work starts; if the card is declined the order is held, and the terms tell the customer to try another card or another route. Bank transfer is prepaid to the shop's account, with the transfer fee on the customer, and an order unpaid by the due date can be canceled. The third is nairu points, which are debited at dispatch, and an order is held if the balance is short. The terms name no card brands or payment processor. A news item dated January 25, 2025 is headed as an important notice about using VISA credit cards; the home page shows only its headline.

Returns are narrow. Once an order is being prepared or has shipped, additions, changes and cancellations are not accepted in principle. After delivery, returns and exchanges are accepted only for a non-conforming item such as an initial defect or a wrong item, and the shop then exchanges or refunds and pays the return shipping. Opened or used items, items that arrived 8 or more days earlier, and items without packaging are otherwise excluded. Refunds go by bank transfer to an account the customer names, and the shop refunds an item that turns out to be sold out after the order.

In October 2026 the terms set shipping at a flat 500円, and they add that an order the shop splits into several parcels carries no extra shipping. A news item dated November 26, 2020 offered 500 points on registering, described as making shipping effectively free; the pages do not say whether the offer still applies.

Who it suits

nairu suits a collector with a delivery address in Japan who wants a wide, tag-driven catalog of new and used DVDs and Blu-rays, including disc-only copies, and a buyer who wants a flat shipping charge. It does not suit a reader outside Japan, anyone who needs English or an overseas-shipping route, or anyone who wants to stream or download. Two things are left to the product pages and the news archive: whether a given disc is censored, and what the VISA notice asks of cardholders.
