There are really a lot of e-book services out there. Kindle, Rakuten Kobo, Comic Seymour, and others... I'm honestly torn about which one is truly recommended. The other day, I read an article that compared 17 major e-book services in detail, which was quite helpful.

To sum up, the service you should choose depends on what you prioritize. If you want to read cheaply with an initial discount, ebookjapan and Comic Seymour are strong options. Especially, ebookjapan offers ongoing discounts even for regular users, making it suitable for long-term use. On the other hand, if you want to read a lot right now, DMM Books' 25% point-back promotion is hard to miss.

If ease of reading is your priority, choose a service with a feature-rich viewer. Adjusting background colors, highlighting functions, switching between portrait and landscape modes—these small features are actually quite important. Also, if you mainly read manga, some services offer spine display, which is a subtle but useful detail in choosing an e-book service.

For those focused on saving money, checking monthly campaigns is key. For example, dブック offers 20% cashback on the 10th, 20th, and 30th of each month, and au Book Pass becomes cheaper the more you buy in bulk. Choosing an e-book service really depends on your reading style, and I’ve realized that the best option varies greatly depending on how you read.
