To make things a bit easier:
・The X axis is the one depicting how many job offers have been listed and available on the Hrog.net website
・The Y axis is the one depicting the average annual salary that users of each language receive, in terms of Japanese yen (円）
To visualize how each salary differs, we also created a chart for you to look at:
"R" is a programming language that specializes in and is used for statistical computing and graphics - hence, linear and nonlinear modelling, classical statistical tests, time-series analysis, classification and clustering etc., and therefore is highly extensible. It is often used at companies to analyse big data and/or machine learniner, and is gaining popularity within general IT companies, as well as Japanese companies that own big-scale web services (as, according to data from 2019 in comparison to data from 2020, the job offers listed on Hrog.net requiring R increased by 266 cases).
While the language itself isn't one that isn't hard to learn, knowledge of statistics is important in learning how to apply it effectively.

GO comes in at second place, and is a programming language that was developed by Google in 2009. This language is one that developers claim is perfect for building projects with high security, high speed and high modularity, and also one that is gaining attention for use in backend development. Compared to data from 2019, job listings that require GO increased by 375 cases, meaning that it's one we can assume that will grow popular in Japan with time.

Due to the fact that it takes time to learn TypeScript, the people who can use it are quite rare in Japan and thus it remains one of the highly paid programming languages at rank 3 - and is assumed to continue to grow over time, as jobs requiring it have increased by 420 cases since 2019.

Developed in 2003, Scala is a high-level general purpose language, compatible with Java (meaning that developers would be able to use standard JVM features and Java libraries) and useful for complex workflows. In 2009, Twitter switched its backend programming language from Ruby to Scala, which is one moment in time that it gained popularity.
In Japan, while jobs that require Scala are relatively low, the fact that it is one of the more difficult langauges to learn and that engineers who can use it are also rare, the salary offered for it remains high. Just for your information; demand for engineers able to utilize Scala has increased by 145 cases since 2019 according to Hrog.net data.

Kotlin is a language, not unlike Scala, that is compatible with Java. Created in 2011, it gained popularity in 2017 when it was selected as a support language for Android, and since then, has been gaining attention from Japanese companies that work on the development of Android applications, meaning that the demand for Mobile Engineers/Application Engineers has also grown.
Compared to Scala, Kotlin is easier to learn, and due to its compatiblity with Java, it can be expected that demand for Kotlin will also grow in the serverside development sector in the future.
