Software Localization Explained: What, Why, and the Real Impact

Have you ever used an app that felt awkward or confusing in your language? If so, you’ve seen why software localization matters. It goes beyond language exchange by modifying content, imagery, and features to accommodate local needs. With localization, products do not just work—they engage users across markets. However, the process has challenges, from design layout adjustments to coping with technical constraints. In this article, let us look at what software localization is, why it is important, and the real difference it makes to businesses and users.

What Is Software Localization?

Simply put, it’s the process of adjusting software to fit users' language, culture, and expectations in different regions. However, it’s more than swapping words—it’s about creating a product that feels tailor-made for each audience.. Imagine ordering food through a delivery app, only to find the menu written in a language you don’t understand, with unfamiliar currency and strange icons. Frustrating, right?

Without localization, even simple tasks can turn into a guessing game. That’s why localization is about adjusting visuals, symbols, formats, and layouts so they make sense to local users. When done right, localization builds trust and comfort. It shows users that the brand “gets them”, both in language and culture. From adapting date formats to using relatable images, every detail matters. In the end, it’s not just about expanding globally, it’s about helping every user feel right at home with the product.

Why You Shouldn’t Skip Software Localization

In a world where technology connects people across continents, launching software globally seems like a golden opportunity. But why exactly is it worth the effort? Let’s break it down:

1. Make Your Product Feel Native
   • Have you ever opened an app and thought, “Wait, what does this button mean?” That confusion happens when a product isn’t adapted for local users. Localization helps your software feel as if it were built right there, in that country, for that audience. When things feel familiar, people are more likely to trust and enjoy using your product.
2. Build a Stronger Connection with Users
   • Customers love to be an afterthought. Imagine having an application with clumsy translations or menus that don't function all that well—there isn't a whole lot of feeling attached, is there? Through localization, you're expressing that you value users' culture and language.
   • That small gesture goes a long way in winning their trust. When customers feel heard and heard, they tend to stay on, recommend your app to other people, and become vocal defenders.
3. Open Doors to New Markets
   • Why limit your user base to a single geographic area when you can internationalize it? Without localization, your application might be stuck behind a language barrier.
   • But with localization, you expose yourself to millions of users who would otherwise skip your product entirely. You're handing them the keys to a car they can drive—now, they'll drive it. Expanding your market not only boosts downloads but also revenue and growth potential.
4. Avoid Costly Misunderstandings
   • Sometimes, a simple symbol or phrase can mean something totally different—or even offensive—in another culture. In this capacity, localization has a function similar to a safety net - it will help you catch culturally-inspired landmines, if not before they go off, at least before they hurt you. It's not just about avoiding an embarrassing mistake - you also need to protect your reputation and show your audience that you're savvy.
5. Stand Out as a Global Brand
   • A localized product shows professionalism and care, setting you apart from competitors who skip this step. It signals to users that you’re serious about meeting their needs, wherever they are. This attention to detail can turn casual users into loyal customers, and loyal customers into advocates who spread the word.

Case Study: How Airbnb Localized Its Software for the Japanese Market

Airbnb's success in Japan highlights not just the importance of localizing your software, but also localizing it according to the inclinations and mores of the local society. The company's success in Japan included several new features aimed at accommodating the shifting vacation travel behavior and unique needs of the Japanese market beyond translation issues. This software localization approach aided Airbnb in improving its user experience in Japan by a huge percentage and doubling the number of domestic visitors. This is how they achieved it:

1. Search Function Tailored to Local Attractions

   • To facilitate accommodation discovery for Japanese users, Airbnb has introduced a new function on their site release: "Search by place/name." This feature is customized to a few of the more common local areas where visitors can search for listings near popular tourist sites, transportation points, or airports.
   • If your travel destination is Kyoto, for example, you can search for a place to stay near some well-known attractions, like Kiyomizu-dera Temple, Gion District, etc. This level of software localization further illustrates how Japanese users prefer to travel—with a focus on convenience and proximity to cultural landmarks, all while exploring local neighborhoods.

2. Enhanced Sorting Features for Better Customization

   • Airbnb further improved its filtering feature to allow users to limit listings with more specific needs like high-rated hosts, range of price, and proximity to landmarks. Even the users have the option of comparing a driving or walking distance from a listing to their desired destination.
   • This feature is particularly valuable for Japanese users who prefer precision in planning their travel, making it easier to find accommodation that suits their preferences. The ability to sort by specific parameters enhances the overall experience, ensuring that users feel the platform was designed with their local needs in mind.

3. New Amenity Filters to Meet Local Preferences

   • To meet growing demand in Japan, Airbnb introduced an 'amenities and equipment' filter, which includes highly requested features such as a kitchen, pool, open-air bath, and jacuzzi.
   • The change wasn't random, but instead the result of a 110% increase in bookings by groups of four or more than pre-pandemic rates. By making the filters more specific, Airbnb enabled groups and families to book suitable accommodations more readily.

4. Adapting to Post-COVID Travel Trends

   • The pandemic has transformed global travel patterns, and Japan has experienced this effect as well. Airbnb has introduced these Japan-specific features in connection with its effort to evolve with the new travel patterns that are arising in the post-pandemic era.
   • According to Yasuyuki Tanabe, Airbnb Japan’s Country Manager, the company has been proactively adapting the platform to respond to shifting demands in the Japanese market. The increasing popularity of group travel, for example, travel among friends or with family, is evident in the upgrades, again demonstrating the significance of software localization in keeping a product abreast and responsive to local trends.

5. Partnering with Local Influencers and Adapting to Regulations

   • Airbnb also demonstrated its commitment to Japan by collaborating with local influencers like architect Kengo Kuma. This collaboration allowed Airbnb to design a lineup of architecture-inspired Experiences that truly connect with Japanese cultural tastes.
   • Similarly, due to increasingly strict short-term rental laws in Japan, Airbnb introduced a partnership-oriented business model, helping hosts comply with local laws and enabling smooth operations amidst a changing legal landscape.

The Results?

Airbnb achieved 75% growth in Japan’s domestic bookings over the four years leading up to September 2023. Destinations reserved via Airbnb were likewise considerable, for example, Ishigaki Island, Nasu Town, and Obanazawa City for the first time. This surge was proof that thoughtful software localization, combining new functions and culturally attuned features, directly impacted user engagement and market growth. By going beyond language and adapting its software to fit Japan’s unique travel culture, Airbnb Japan showed how localization can unlock new opportunities and deepen user trust.

Conclusion

It can be concluded that software localization can transform a product from simply working to genuinely resonating with its users. As we have learned from Airbnb in Japan, when we prioritize local features, visuals, and user experiences, we create deeper engagement, foster trust, and grow the bottom line.
