Rust in Japan - Language Guide

Rust, the programming language created as an open-source project back in 2010, has become a relatively popular language since its conception. 

While it may not be at the top of the charts in terms of popularity, it still ranks 17th in job listings on Japan Dev. As the language is beginning to catch the attention of many newly established companies in Japan and demand for Rust engineers is on the rise, Rust’s time under the spotlight is long overdue.

So, in this post, I’ll talk about Rust in Japan, how it’s used, and which notable companies support this multi-paradigm language. I’ll also explore the financial prospects of Rust developers in Japan and provide a few tips on getting a Rust job here.

Let’s dive right in.

The Popularity of Rust Programming Language in Japan

Although Rust isn’t exactly a top-of-the-charts programming language in Japan, it’s still very much in the game. 

At Japan Dev, we’ve collected lots of data over the years from the countless companies and listings featured on our job board. We’ve analyzed all the listings we’ve had on the platform, checked which languages are the most in demand, and ranked them accordingly. 

According to our list, Rust is the 17th most popular programming language in Japan:

Mind you, this isn’t just a popularity contest but data based on the number of jobs available. Considering this and the fact that Rust developers still earn more on average compared to other languages above it on the list, learning Rust is still worth it.

Besides, Rust has started to gain popularity among startups in Japan in recent years, and even some larger-scale international companies have adopted it in their day-to-day operations. 

So, it’s safe to say that Rust developers can find jobs relatively quickly in Japan. With that in mind, let’s see exactly how Rust is used and its most common applications.

Rust in Action: How Is Rust Used in Japan?

As you may know, Rust is a general-purpose programming language by nature, so it’s utilized in many ways in a wide range of use cases. As it puts a stronger emphasis on type safety while maintaining fast performance, some companies use Rust as a replacement for C/C++. It’s also used for server-side applications and command-line tools.

So, thanks to its versatility and general applicability, it’s safe to say that Rust is fairly popular in Japan’s software development scene, even if it isn’t exactly competing for the most popular language spot.

Now, let’s talk about the financial prospects of Rust developers in Japan.

Rust Salaries in Japan: Financial Prospects of Rust Developers

As you can already tell by the table we’ve shared above, the median salary for Rust developers in Japan is ¥8.5 million annually.

If you’ve read my post on developer salaries in Japan, this is above the average of 7 million that platforms like Glassdoor claim. In fact, if we take the average developer salary as 4.6 million, as the Japanese survey service DODA suggests, the difference is even bigger, but ultimately, it all depends on the type of company. 

Companies in Japan can be separated into three categories according to their salary range:

• Traditional Japanese companies that typically offer the lower pay

• Modern Japanese tech companies with global practices and a more satisfying salary

• Large international companies that pay the most handsomely 

Considering Rust’s recent popularity among startups and large companies, companies that hire Rust engineers are in the second and third categories. Therefore, despite not being a “top language,” Rust jobs still offer above-average salaries, good employment practices, and benefits.
