About One Japanese
One Japanese is an education app from developer One Japan that gathers Japanese language study into a single mobile package. It installs under the package name com.onestudio.onejapanese and is built for learners who want their practice material carried on their device rather than searched for each time they sit down to study.
A Practical Study Companion As an education release, the app is organised around steady, repeatable study rather than one-off reference lookups. Everything it ships with lives inside one install, so a learner can open the app and continue where they left off without juggling separate resources, notebooks or bookmarks. The focus stays on helping a beginner or returning student build routine with the language.
Compatibility and Supported Devices The build requires Android 6.0 or newer. Anything above that baseline counts as newer devices, so recent handsets and tablets should launch and run the app without issue. Users on older hardware should check their system version before installing to confirm it clears the stated minimum.
Storage Space Needed for Install The download footprint is 85.2 MB. That is the size of the package you receive, so it is worth keeping a comfortable margin of free space on your device for the install to complete cleanly and for the app to create any working files it needs during normal use.
Version and Release Details The current release is version 2.2.8, published on 2026-09-03. The listing does not supply a content rating, so anyone choosing the app for a younger learner may want to review the material directly before handing over a device.

Frequently Asked Questions
How much free space should I have before installing One Japanese?
The package for One Japanese is 85.2 MB, which is the size you download. Leave some extra room beyond that figure on your device so the installation can complete and the app has space for any working files it creates during use. If your storage is nearly full, clearing a few hundred megabytes first is a sensible precaution.
Which Android versions does this build work with?
The build requires Android 6.0 or newer. Devices running that version or anything above it fall within the supported range, so most recent handsets and tablets are covered. If your device is older than the stated minimum, the app will not be compatible, and you would need a device that meets or exceeds the requirement.
What version am I getting and when was it released?
The latest listed version of One Japanese is 2.2.8, released on 2026-09-03. That is the current build offered by developer One Japan. If you are comparing against an older copy of the app already installed on a device, this is the release to update to in order to have the most recent package.
What is the exact package name of the app?
The package name is com.onestudio.onejapanese. This identifier is what the system uses to recognise the app once it is installed, and it stays the same regardless of version. It is useful for confirming you have the right application, checking installed builds, or locating the app in your device's application settings.
Does the listing give a content rating?
No, the content rating for this app is listed as unknown. Because no age classification is supplied, anyone considering the app for a child or younger learner should look through the material themselves first to judge whether it suits that person's age and study level.
