We found 35 issues in Muji's checkout, a modelled 14.6–44.3% of conversions.

The problem

When the checkout form has an error, the store clears out information the shopper already typed correctly.

Why it matters

A shopper who typed their address once and lost it to a form error frequently will not type it twice. This is a critical-severity leak at the very end of the funnel, where every lost buyer was seconds from paying.

The problem

The cart does not show a full cost breakdown. Some of subtotal, shipping, tax, or total is missing before checkout.

Why it matters

Baymard research: 48% of shoppers abandon at checkout because of surprise costs. If the cart hides shipping or tax until the final step, you are training buyers to bail.

The problem

The full order total (including shipping and tax) isn't visible before the buyer starts entering payment details.

Why it matters

Surprise costs at the payment step are the #1 abandonment trigger in every study. Buyers want the final number before their card leaves the wallet.

The problem

The Add-to-Cart button is not visible above the fold on mobile. Shoppers have to scroll to find how to buy.

Why it matters

On mobile especially, buyers scan the top of the page and decide within seconds. If the primary purchase button isn't in that first view, many will leave before scrolling.

What to do

Add a fixed/sticky 'Add to Cart' button in dark maroon (matching the header/footer bar color) directly below the $2.90 price line so it stays visible without scrolling, similar to how the 'MUJI Rewards' bar is pinned at the bottom.

The problem

The product page doesn't tell shoppers when their order will arrive. There is no delivery date or lead-time estimate.

Why it matters

Buyers often decide between two stores based on delivery timing, especially for gifts and urgent purchases. Uncertain timing pushes them to competitors who are clear.

The problem

The main content of the product page takes longer than 2.5 seconds to appear ("Largest Contentful Paint" is slow).

Why it matters

Every extra second of load time drops conversion by ~7% (Google, 2024). 2.5s is Google's threshold for a good experience. Above 4s is considered poor and hurts search rankings too.

The problem

The cart does not clearly show tax, either as an amount or as a note that tax will be calculated at checkout.

Why it matters

Buyers in the US and Canada expect a tax line before they commit. Silence at the cart step means a jump in the total at checkout, and that jump is what makes them abandon.

The problem

The checkout has more than 8 form fields. Industry-best checkouts collect 6-8 fields; industry-average is 11.3.

Why it matters

Every extra field drops conversion by roughly 2%. Fields cost you money in a direct, measurable way. A checkout with 13 fields loses ~10% of buyers compared to one with 8.

The problem

The checkout has no address autocomplete (Google Places, Loqate, SmartyStreets, or similar). Shoppers type every line of their address manually.

Why it matters

Address autocomplete cuts address-entry time roughly in half on mobile and drops delivery-failure rates from typos. It also feels premium, buyers notice.

The problem

The checkout page does not show when the order will arrive. Buyers commit to buying without knowing the delivery date.

Why it matters

Delivery timing is often the deciding factor between two stores. If your competitor tells the buyer "arrives Tuesday" and you say nothing, you lose. Especially for gifts.

The problem

The checkout has no signals declaring it can be driven by AI agents. No ACP or UCP meta tags, no /.well-known/agentic-commerce endpoint, no Stripe ACP integration.

Why it matters

OpenAI's Agentic Commerce Protocol (ACP) and Google's Universal Commerce Protocol (UCP) are the emerging standards for agent-driven checkout. Stores that declare readiness get preferential routing from ChatGPT and Google AI. This is 2026's biggest new distribution channel.

The problem

The product page shows no star rating or review summary above the fold. Shoppers have to scroll to find social proof.

Why it matters

Ratings are the fastest trust signal on a product page. A shopper who lands and doesn't see any social proof in the first view assumes it's a low-quality product or a new store.

What to do

Since this product has 0 reviews, replace the empty star row with a subtle prompt like 'Be the first to review this product' linked to the review form, so shoppers aren't left wondering if reviews are broken or simply absent.

The problem

There's no returns or exchange policy communicated on the product page itself. Shoppers have to hunt the footer or FAQ to find it.

Why it matters

"What if I don't like it?" is the last question in every purchase. If the answer isn't obvious, hesitation kills conversion, especially for higher-price items and apparel.

What to do

Expand the 'Shipping & Returns' box under the Add to cart button to show the actual return window (e.g. 'Return within 30 days') directly in the visible text instead of hiding it behind the 'Learn more' link.

The problem

An aggressive popup (newsletter, discount, chat prompt) covers this product page shortly after it loads. Cookie banners don't count; this is the newsletter-style overlay.

Why it matters

Popups on first visit interrupt intent. First-time shoppers are still evaluating; a modal that blocks the price or ATC is a fast way to lose them.

What to do

The black-and-maroon 'Up to 50% OFF Back To School' promo bar and the floating 'Chat with us' bubble sit above/over content edges but don't block the price or Add to cart button; still, dismiss the promo bar after first view or make it collapsible and move the chat bubble so it doesn't risk overlapping the sticky footer 'MUJI Rewards' bar on smaller viewports.

The problem

Cart items can't be edited in place: quantity changes or removals are missing or require leaving the cart.

Why it matters

Shoppers adjust quantities at the last moment. If editing is hard, they either abandon or check out with the wrong items and return them later.

The problem

The primary checkout button doesn't visually dominate the cart page. It competes for attention with promo-apply, save-for-later, or continue-shopping controls.

Why it matters

Cart is a decision moment. If the buyer's eye doesn't land on "Checkout" instantly, they scroll around, get distracted by promo hunting, and leave. Making the checkout CTA the biggest, brightest thing on the page measurably lifts completion.

What to do

Differentiate the main 'Check out' button in the subtotal box with MUJI's red accent color (used in the top banner and 'MUJI Rewards' bar) instead of black, so it doesn't blend with the black 'Save for later' button and isn't visually diluted by the three payment icon buttons (Shop, PayPal, GPay) stacked right beneath it.

The problem

The structured product data that AI shopping agents read (ChatGPT, Google, Copilot) is incomplete on this page. Some or all of these are missing: product ID (GTIN), brand, review data, availability, shipping details.

Why it matters

AI-referred traffic converts 42% higher than regular traffic (Adobe, 2026). But agents only recommend stores whose product data they can read. Incomplete data means invisible to AI shoppers.

The problem

On this long product page, the Add-to-Cart button disappears once the shopper scrolls down. There is no sticky bar that keeps it reachable.

Why it matters

Shoppers scroll deep into reviews and details, decide to buy, and then have to scroll all the way back up. Every extra scroll is a chance to get distracted and leave.

The problem

The product gallery only shows the product isolated on a white background. No lifestyle, in-use, or scale reference images.

Why it matters

White-background photos are neutral but not persuasive. Lifestyle images (worn, used, in a real setting) lift conversion 30-50% and cut returns because buyers understand the product better.

What to do

Add at least one lifestyle photo showing the Parachute Cloth Gadget Case Short Strap actually attached to a gadget case and being carried or held (similar to how the 'Retractable Reel Strap' or bag organizer products could be shown in use), replacing one of the four flat product-only thumbnails on the left.

The problem

The product page does not have a Q&A section or a real specifications table. Shoppers cannot answer their own questions before buying.

Why it matters

Considered purchases (electronics, appliances, tools, tech gear) live and die on the details page. When shoppers cannot find dimensions, materials, compatibility, or answers to obvious questions, they leave to research on Amazon or a competitor and often buy there instead.

The problem

Some interactive elements on the mobile page are smaller than 44x44 pixels. Fingers struggle to hit them accurately.

Why it matters

44x44 pixels is the minimum touch target Apple and the WCAG 2.2 guidelines recommend. Below that, mis-taps happen: buyers hit the wrong swatch, wrong quantity, wrong link, and abandon in frustration.

The problem

The cart does not show a delivery estimate for each item. Buyers cannot see when their order will arrive.

Why it matters

Delivery timing is the second-biggest factor after price, especially for gifts and urgent purchases. Uncertain arrival dates push buyers to competitors who are clear.

The problem

A discount has been applied but there is no explicit line showing the discount amount and label. The saving happens silently.

Why it matters

Buyers who applied a code want to see it working. A silent adjustment feels like the code did not work, and they may re-apply, try a different code, or abandon in frustration.

The problem

The cart page is broken on mobile: content overflows the viewport, requires horizontal scrolling, or has buttons that fall off the screen.

Why it matters

More than 60% of ecommerce traffic is mobile. A cart that requires horizontal scrolling doesn't lose 60% of buyers, it loses closer to 90% of the mobile ones. This is fatal and easy to check with a phone.

What to do

Reposition or shrink the black 'Chat with us' pill and the red vertical 'Reviews' tab so they don't overlap the subtotal/shipping text and checkout button; move them to a fixed corner with lower z-index or collapse them into a small icon that expands on tap.

The problem

The checkout uses separate First Name and Last Name fields instead of a single Full Name field.

Why it matters

Two fields cost two taps and two keyboard focuses on mobile. Baymard research shows a single Full Name field measurably lifts checkout completion, especially on phones.

The problem

Some input fields use `type="text"` when they should use `type="email"`, `type="tel"`, or `inputmode="numeric"`. Mobile keyboards do not adapt.

Why it matters

The wrong keyboard is a small papercut on every entry. Type an email on a phone with a QWERTY (no @ key) or a phone number without the number pad, and completion drops.

The problem

Personal-info fields are missing correct `autocomplete` attributes, or one is set to `autocomplete="off"`. Password managers and browser autofill do not work smoothly.

Why it matters

WCAG 2.2 requires autocomplete on personal-info fields for accessibility. Beyond compliance, correct autocomplete makes checkout a 2-tap experience for returning buyers, huge for mobile conversion.

The problem

The checkout does not offer a "Same as shipping" checkbox for the billing address, with the box checked by default. Buyers have to type their address twice. (This rule only applies to physical-product stores.)

Why it matters

For most orders, billing and shipping addresses are the same. Making the buyer re-enter their address is duplicate work and a common source of typos.

The problem

The phone number field is required with no explanation why. Buyers who value their privacy hesitate or abandon.

Why it matters

"Why does a t-shirt store need my phone number?" is a real objection. Without a rationale, some shoppers will not give it and will leave.

The problem

The checkout form uses placeholder-only labels: the field's purpose is shown as grey text inside the input, and disappears the moment the buyer starts typing.

Why it matters

Placeholder-only labels violate WCAG accessibility, but they also just cost sales. A buyer who types a wrong value, then forgets what the field was for, has to erase everything to see the label again. Frustration compounds.

What to do

Add small static labels (e.g. 'First Name', 'Address', 'City', 'ZIP code') above each input box in the Shipping address section, similar to the 'Country/Region' field which already has a label above its dropdown, so users can still see the field purpose after typing.

The problem

The final checkout button is labeled with a generic verb like "Continue", "Next", or "Submit" instead of a specific action like "Place Order" or "Pay $X".

Why it matters

The final tap is a high-anxiety moment. "Continue" doesn't tell the buyer what will happen. "Place Order" or "Pay $89.00" is unambiguous: click, and the money moves. Clarity here removes the last hesitation.

What to do

Since this is still an intermediate step, keep 'Continue to shipping' here but ensure the final step's button (on Payment page) is changed to a specific action verb like 'Pay $150.00' or 'Place Order' instead of a generic label like 'Continue' or 'Submit'.

The problem

The payment step doesn't show any trust or security signals near the payment fields (padlock icon, "Secure checkout", PCI badge, Verified by Visa).

Why it matters

Buyers are at their most anxious when typing card numbers. A visible security signal near the field removes that anxiety and lifts conversion.

What to do

Add a small lock icon with 'Secure checkout' text directly under the 'Express checkout' label (near the Shop/PayPal/G Pay row at y~0.17) and/or beside the Email field, since currently there is no SSL/PCI badge anywhere between the MUJI logo and the shipping form.

The problem

There's no visible way to reach help from the checkout page: no phone number, no chat widget, no "Need help?" link.

Why it matters

When something goes wrong mid-checkout (a declined card, a missing address field), a visible help option is the difference between recovery and abandonment.

What to do

Add a 'Need help? Contact us' link next to the existing footer links (Refund policy, Shipping, Terms of service, Cookies) at the bottom left, or better, add a small chat bubble icon in the bottom-right corner of the page so users mid-checkout can get support without losing their place.

The problem

The checkout does not declare support for delegated-payment (ACP tokenization). Agents cannot pass a tokenized payment method on the buyer's behalf.

Why it matters

Delegated-payment is the piece that actually lets agents complete a purchase without asking the buyer to type their card. Stripe and PayPal both support this via their ACP modes. Without it, agents can prep the order but hand it back to the buyer to finalize.

The problem

Cart line items do not include machine-readable product identifiers (SKU, GTIN, product_id). Agents see only display names.

Why it matters

Without a stable identifier per line, agents cannot cross-check items against a catalog, apply price rules, or reconcile the order. Display names change with translation and localization, they are not safe identifiers.
