Let’s be honest for a second: when you look at a global app like Netflix or Spotify, it’s easy to assume everyone sees and interacts with it the same way. You open the app, you see a row of shows, you swipe left or right, and you press play. Simple, right?
But here’s the thing—that “simple” assumption is exactly where most companies fail if they aren’t paying attention. The digital world isn’t a flat map where every user’s thumb works the same way and every eye scans text from the same direction. In fact, the physical and cultural geography of your user base changes everything about how an interface needs to breathe, move, and feel.
I’ve spent years digging into the mechanics of global product design, and I can tell you that adapting for Japan and Saudi Arabia isn’t just about translation. It’s about reimagining the user’s journey from the ground up. Let’s break down how these tech giants are quietly revolutionizing their interfaces for two very different, yet equally critical, markets.
The Japanese Market: Precision, Hierarchy, and the “Swipe” Nuance
When we talk about Japan, we’re not just talking about a market with high smartphone penetration. We’re talking about a culture where design is obsessed with detail, hierarchy, and minimizing cognitive load. Japanese users are some of the most discerning in the world, and they notice when an app feels “foreign” or uncomfortable.
1. The Swipe Gesture: Directional Intuition
In the West, the standard for image carousels is often a horizontal swipe. But in Japan, there’s a fascinating nuance. While horizontal swiping is common, many Japanese apps lean heavily into vertical scrolling as the primary navigation method, even for content that Western apps might present horizontally.
Why? Because vertical scrolling feels more like reading a newspaper or a menu, which is the traditional way Japanese users consume dense information. It’s linear, it’s predictable, and it reduces the mental effort of wondering “does it go left or right?”
Real-World Example: Look at Spotify’s Japanese interface. While the global version pushes horizontal rows for “Made for You” playlists, the Japanese app often integrates these into a more vertical, magazine-style feed. The “swipe” here isn’t just a gesture; it’s a transition that feels smoother, with animations that respect the user’s need for clarity over flash.
But wait—what about the actual direction of the swipe? In Japanese app design, there’s a strong preference for right-to-left interactions in certain contexts, even though the language is read left-to-right in modern digital text. This is because many Japanese interfaces mimic the way people flip through pages in a book or scroll through a timeline, which feels more natural when thumbing upward or swiping from the right edge.
2. Information Density and the “Ma” (Negative Space)
Japanese users are comfortable with higher information density than their Western counterparts. However, this doesn’t mean clutter. It means organized complexity. Netflix, for instance, adapts its Japanese homepage by offering more granular categories and sub-genres than the US version.
In the US, you might see “Trending Now.” In Japan, you might see “Trending Now: Sci-Fi & Fantasy > Mecha > Popular.” This level of specificity is crucial. Japanese users appreciate being able to drill down quickly.
The Design Principle: This is where the concept of “Ma” (間) comes in. “Ma” refers to the negative space or pause between elements. In Japanese design, empty space isn’t wasted; it’s essential for breathing room. So, while there’s more information, it’s spaced out with more deliberate padding and clear visual hierarchy. Buttons are larger, text is crisp, and there’s no ambiguity about what happens when you tap.
3. Character and Typography
Japanese text is complex. It mixes Hiragana, Katakana, and Kanji. A font that works for English might look cramped or illegible in Japanese. Netflix and Spotify both use custom-tuned typefaces for their Japanese apps. For example, Spotify uses a cleaner, more open font for Japanese lyrics and playlist descriptions to ensure readability on smaller screens.
Code Snippet Insight: If you were developing a React Native app for the Japanese market, you’d see something like this in your styling:
// For Japanese text, font size and line height need adjustment
const japaneseStyle = {
fontFamily: 'NotoSansJP-Regular', // Specific Japanese font
fontSize: 16,
lineHeight: 28, // Increased line height for vertical text readability
letterSpacing: 0.5,
};
// For English, you might use a tighter spacing
const englishStyle = {
fontFamily: 'Helvetica Neue',
fontSize: 16,
lineHeight: 24,
letterSpacing: 0,
};
This isn’t just aesthetics; it’s accessibility. If the line height is too tight, Japanese users will struggle to track their eye down the page.
The Saudi Arabian Market: RTL, Honor, and Cultural Respect
Now, let’s pivot to Saudi Arabia. Here, the challenge is fundamentally different. It’s not about density or gesture nuance; it’s about orientation and cultural alignment.
1. Right-to-Left (RTL) is Non-Negotiable
Saudi Arabia uses Arabic, which is an RTL language. This means text flows from right to left. But it’s not just the text. The entire interface must mirror.
If you’re a product manager in the US, your “Home” button is on the left, and your “Profile” is on the right. In Saudi Arabia, that’s flipped. The “Profile” is on the left, and “Home” is on the right. This isn’t a minor tweak; it’s a complete redesign of the navigation structure.
Real-World Example: Look at Netflix’s Saudi app. The navigation bar is mirrored. The “Back” arrow points to the right instead of the left. When you swipe to go back, you swipe from the left edge, not the right. This feels natural because Arabic readers are accustomed to starting on the right.
The Problem with “Fake” RTL: Many companies make the mistake of just flipping the text but leaving the icons and layout in LTR mode. This is a disaster. It creates cognitive dissonance. If the “Play” icon is on the right but the text next to it is Arabic, the user’s brain stumbles. Netflix and Spotify invest heavily in true RTL adaptation, ensuring that every icon, every arrow, and every carousel moves in the correct direction.
2. Cultural Sensitivity in Content and Payment
Saudi Arabia is a conservative market with specific cultural norms. This affects more than just the interface; it affects what’s shown and how you pay.
- Content Moderation: Netflix adapts its library for Saudi Arabia, removing or rating content that might be sensitive in the region. But beyond that, the way it presents this content matters. Thumbnails are chosen carefully to avoid cultural missteps.
- Payment Methods: Credit card penetration is growing, but it’s not 100%. In Saudi Arabia, local payment methods are crucial. Netflix and Spotify integrate with STC Pay and Mada, which are local payment networks. If you try to pay with a US-style credit card form in Saudi Arabia, you’ll lose conversions.
User Flow Example: When a Saudi user tries to subscribe, they see:
- “Pay with Mada” (a local debit network)
- “Pay with STC Pay” (a mobile wallet)
- “Pay with Credit Card” (global)
This localization of payment options is as important as the RTL layout. It’s about trust. If I can pay with a method I trust, I’m more likely to subscribe.
3. The “Swipe” in RTL: A Directional Shift
In an RTL interface, the “swipe” gesture changes meaning. In LTR, swiping left usually means “next” or “forward.” In RTL, swiping right means “next” or “forward.”
This is subtle but critical. If you swipe left on a Saudi Netflix app, you might expect to go forward in a playlist, but instead, you go back. This can be frustrating if the app doesn’t respect the RTL gesture mapping.
How Netflix Fixes This: Netflix uses device orientation detection combined with language settings. If the app detects the system language is Arabic (SA), it automatically switches the gesture map:
- Swipe Right = Next
- Swipe Left = Previous
This is often handled by a simple configuration in the app’s settings, but it’s backed by a robust state management system.
Why This Matters: The Business Case for Localization
You might be thinking, “Is all this really necessary? Can’t they just translate the text and call it a day?”
The answer is a resounding no. Here’s why:
1. User Trust and Retention
When an app feels “local,” users trust it more. They feel understood. In Japan, a well-designed, dense but clear interface signals that Netflix respects their preferences. In Saudi Arabia, an RTL interface that works seamlessly signals that Spotify understands their culture. This trust leads to higher retention rates.
2. Reduced Churn
Poor localization leads to churn. If a Saudi user can’t easily find the subscription button because it’s on the wrong side, they might give up. If a Japanese user finds the interface too sparse and confusing, they might cancel.
3. Market Share
Japan and Saudi Arabia are massive markets. Japan is the third-largest economy in the world, and Saudi Arabia is the largest in the Middle East. Ignoring localization means leaving money on the table.
The Technical Implementation: How It’s Done
Let’s get a bit technical. How do these companies actually implement these changes?
1. RTL Support in Code
Most modern frameworks (React Native, Flutter, SwiftUI) have built-in RTL support. But it’s not automatic. Developers must:
- Use logical properties instead of physical ones (e.g.,
margin-startinstead ofmargin-left). - Test with both LTR and RTL layouts.
- Ensure icons are mirrored where appropriate (e.g., a “back” arrow should point the opposite way in RTL).
// React Native example using logical properties
<View style={{ flexDirection: 'row', justifyContent: 'flex-start' }}>
<Text style={{ marginLeft: 10 }}>Home</Text>
<Text style={{ marginRight: 10 }}>Profile</Text>
</View>
Note: In RTL, marginLeft and marginRight don’t automatically flip. You need to use marginStart and marginEnd.
2. Font Handling
For Japanese, you need to load specific fonts. For Arabic, you need fonts that support the complex ligatures and diacritics.
// Loading a Japanese font
import { AppRegistry } from 'react-native';
import { registerFont } from 'react-native-fonts';
registerFont('NotoSansJP', require('./assets/fonts/NotoSansJP-Regular.ttf'));
3. A/B Testing Across Markets
Netflix and Spotify run extensive A/B tests in each market. They might test different thumbnail sizes in Japan versus Saudi Arabia to see what drives more engagement. This data-driven approach ensures that every design choice is backed by user behavior.
Conclusion: It’s Not Just Translation, It’s Transformation
Adapting apps for Japan and Saudi Arabia isn’t a checkbox exercise. It’s a transformation of the user experience. It’s about understanding that a Japanese user’s thumb moves differently, that a Saudi user’s eye scans from right to left, and that trust is built through respect for cultural nuances.
Netflix and Spotify have mastered this by investing in local teams, conducting deep user research, and building flexible technical architectures that can adapt quickly. The result? An app that feels like it was made for you, no matter where you are.
So, the next time you swipe through your favorite shows or playlists, take a moment to appreciate the invisible labor that went into making it feel so natural. It’s not magic; it’s meticulous, empathetic design.
