Kinship is a marketplace. Your piece is supplied by one of our established luxury retail Partners, primarily in Japan. Every Partner is accepted only after a thorough audit and a full business background check, and our Partner Network includes only established retailers that sell new products. We never sell second-hand items.

Every item passes professional third-party authentication plus our own quality-control checks. An independent third-party specialist verifies the piece first. Our own quality-control team then inspects it at our Hong Kong inspection hub for condition and defects. Only then is the order dispatched.

Every order arrives in the brand’s original packaging with the original labels attached.

Every purchase is backed by our Authenticity Guarantee. The full process, and what to do if you have a concern, is set out on our Authenticity Guarantee page.

We do not publish their names.

We engage brand-specific Japanese authenticators, each with decades of experience in the luxury fashion industry. We keep both our Partners and our authenticators confidential: many businesses in this industry compete over the same stock, and disclosing these contacts would benefit competitors. Our customer care team gives the same answer if you write and ask.

What we can tell you is exactly what happens to your piece and who does what — see our Authenticity Guarantee page.

Kinship operates as a marketplace. Products are offered through our network of established luxury retail Partners, primarily in Japan. The purchase contract for a piece is between you and the Partner that supplies it, as set out in our Terms of Service.

Every Partner is accepted only after a thorough audit and a full business background check. Our Partner Network includes only established retailers that sell new products. We never sell second-hand items.

We do not publish the names of individual Partners. Our Partner Network is our company’s proprietary asset, and many businesses in this industry compete over the same stock.

Kinship is a marketplace, and we list pieces from across a network of established luxury retail Partners, primarily in Japan.

No single boutique carries every size, and stock does not run out everywhere at the same time. A size that has gone at one retailer is often still on the shelf at another. Drawing on many established retailers rather than one is why a piece that is sold out in your own market may be still available here.

There is a trade-off, and it is the reason our delivery estimate is 5–10 business days rather than next day. Some pieces — usually the harder-to-find ones — are secured from a Partner after you place your order, then verified by an independent third-party specialist and checked by our own quality-control team at our Hong Kong inspection hub before dispatch.

You are never locked in while that happens. You can cancel any unshipped order at any time for a full refund.

Availability changes as stock moves across our Partner network — a piece that is unavailable today can return when a Partner has it again.

Email contact@kinship.jp or use the form on our Contact page with the piece, colour and size you are after, and we will let you know as soon as it becomes available again.

Every order arrives brand new, in the brand’s original packaging - including the brand box and dust bag where the brand provides them - with the original brand tags and labels attached.

Please note we do not include store receipts, purchase invoices, or paper certificates. Our checks stand behind your piece instead: an independent third-party specialist verifies it, and our own quality-control team inspects it at our Hong Kong inspection hub before it is dispatched to you.

We have several verification stages when customers place an order; this is done to provide our customers with the highest level of security.

If your order is successful, you should receive an order confirmation within the next 10 minutes via the e-mail address provided at checkout. If you do not see it, please check your spam folder - and if it still has not arrived, contact us and we can assist you.

Once an order is submitted, we are unable to change the ordered products or the quantity selected.

In this situation, we suggest you contact us immediately so we can cancel the incorrect order before it is dispatched. Thereafter, we recommend you place a new order for your desired item(s) on our website at your own convenience.

At the checkout page, to apply your discount code, enter your code in the "Gift card or discount code" field, and click on “Apply”. Be sure that there are no additional spaces before or after the discount code.

Kindly note that only one discount code is valid per order, meaning a discount code cannot be combined with an additional discount code.

To place your order, select the item(s) that you wish to purchase and add it to your shopping cart. Then, proceed to the checkout page where you must fill in your personal information and pay for the order. Make sure to double check that you have filled in your details correctly to ensure that you receive all the necessary info and that your order is delivered without any complications.

If you need any help, we strongly advise you to speak to one of our Customer Service Representatives by sending us a message on our Contact Us page.

In the event you wish to cancel your order, please contact us immediately.

If your order has not yet been dispatched, we will cancel it and issue a full refund to your original payment method. Because orders are usually processed and dispatched within 1-2 business days, please reach out as soon as possible.

If your order has already been dispatched, we can no longer cancel it. You can instead request a change-of-mind return within 14 days, beginning the day after delivery, as described in our Return & Refund Policy.

Your order confirmation should arrive within about 10 minutes of placing your order. If you do not see it, please check your spam or promotions folder first.

Your shipping confirmation with tracking information arrives separately, within 3-4 business days of placing your order.

Once the carrier has made their first delivery attempt to your address, you can contact the carrier’s local office and ask them to deliver your package to your nearest carrier access point. Some may even allow you to arrange for your order to be dropped off at an access point at any time.

Your package will be delivered to a secure location where you can pick it up at your own convenience.

Many items dispatch from our Hong Kong inspection hub within 1-2 business days. High-demand pieces with limited supply are sometimes sourced from our Partners after you place your order, then verified by an independent third-party specialist and checked by our own quality-control team before dispatch.

On average, delivery still takes 5-10 business days. If your order needs longer, we will keep you updated - and you may cancel any unshipped order at any time for a full refund.

If you wish to change your delivery address, please contact us and we will do our best to assist you in this matter.
