BOOK☆WALKER Global StoreWhy Choose BOOK☆WALKER?
BOOK☆WALKER is an all-in-one e-bookstore specializing in manga, light novels, and magazines, catering to both Japanese and international audiences. Here are some reasons why it’s an excellent choice for Japanese learners:
Access Japanese Manga Anytime, Anywhere – No VPN Required!
One of the biggest hurdles for Japanese language learners outside Japan is the difficulty of accessing original Japanese-language books and manga due to regional restrictions. Many Japanese e-book services are limited to users within Japan, requiring a Japanese address, payment method, or even a VPN to bypass geographic restrictions.
However, BOOK☆WALKER eliminates these barriers entirely. As an internationally accessible e-book platform, it allows users from around the world to legally purchase and read Japanese-language manga without needing a VPN or a Japanese credit card. This means that whether you’re in the United States, Europe, or anywhere else, you can enjoy a vast library of Japanese content hassle-free.
You can use both the Global Store (English version) and the Japan Store with the same account.
The Global Store exclusively provides English e-books, while the Japan Store mainly offers Japanese e-books. You can access both stores using a single account. All information in the Global Store is in English. New members can register at either store, allowing those who are not proficient in Japanese to start using the service without stress by registering as a new member in the Global Store.
Depending on your level of Japanese proficiency, you might need to rely on automatic translation when purchasing Japanese works from the Japan Store. Nonetheless, for non-native Japanese speakers, this service appears to impose significantly less burden when starting to use it.
Save Big on Manga – Exclusive Discounts & Rewards!
For avid manga readers and Japanese learners, cost can be a major concern when building a digital library. Fortunately, BOOK☆WALKER makes it easier and more affordable to enjoy Japanese-language manga through frequent discounts, time-limited free volumes, and a generous rewards system.
One of the standout features of BOOK☆WALKER is its coin-back promotions, where users earn digital coins with every purchase. These coins can later be used as store credit, effectively providing cashback on future purchases. Additionally, the platform regularly offers seasonal sales, publisher-specific discounts, and limited-time campaigns, allowing users to grab popular manga and light novels at reduced prices.

Another exciting perk is the free trial volumes available for a limited time（無料！）. These allow readers to explore different series without committing financially, making it a fantastic way to discover new titles before making a purchase.

As a service of the Japan Store, there is a flat-rate service where you can access over 90 manga magazines, more than 30,000 hardcover volumes, and over 20,000 light novels and literary works. Since it is available at a reasonable price, I believe it offers significant benefits to those who simply want to immerse themselves in Japanese as much as possible. There are two types of unlimited reading services.
