「電子書籍って便利そうだけど、実際どうなの？」
そんな悩みを抱えている方に向けて、この記事ではAmazonの電子書籍サービス・端末「Kindle」について、メリット・デメリットからお得な利用方法、おすすめな人まで徹底解説します。
これから電子書籍デビューを考えている方も、すでにKindleを使っているけれど活用しきれていない方も、ぜひ参考にしてください。
Kindleとは？基本をおさらい
More than Kindle
Kindle has two main meanings.
- Kindle device: A dedicated reader for e-books.
- Kindle app & store: An e-book service usable on smartphones and PCs.
In other words, you don't need a dedicated device; you can start using Kindle right away by simply installing the app on your smartphone.
Furthermore, there is also a subscription service called "Kindle Unlimited" that offers unlimited reading for a monthly fee, and understanding this as well broadens your options.
Kindleのメリット
① 本棚がいらない、収納スペースの節約になる
Owning hundreds of physical books requires not only bookshelf space but also considerable thought about storage.
With Kindle, you can store thousands of books on a single device or smartphone. You won't need to move books when you move house, and your rooms will be tidier.
② 荷物にならない、持ち運びが楽
Carrying multiple physical books on trips or business travel is difficult, but with Kindle, everything is contained on one device or smartphone.
Another advantage is that if your mood for reading changes, you can download a different book on the spot and start reading.
③ 目が疲れにくい（Kindle端末の場合）
The dedicated Kindle device uses a technology called "E Ink" (electronic paper), which has a paper-like texture and is easy on the eyes.
Unlike smartphone or tablet screens, it has less blue light impact, and many users report they can enjoy reading before bed without guilt.
④ すぐに購入・入手できる
Another strength of Kindle is that you can purchase and start reading immediately without the hassle of going to a bookstore.
The speed at which you can get a book the moment you decide you want to read it is an experience that physical books cannot offer.
⑤ 文字サイズや明るさを自由に調整できる
With physical books, the text size is fixed, but with Kindle, you can adjust the text size, font, brightness, and even colour temperature to your preference.
This is also a welcome feature for those who find it harder to see small text as they get older.
⑥ 読み放題サービスでコストパフォーマンスが良い
More than Kindle
By subscribing to "Kindle Unlimited" for ¥980 per month (tax included), you get unlimited access to over 5 million eligible titles. It covers a wide range of genres, including novels, business books, practical books, manga, and magazines, so if you read more than one or two books a month, it's often more cost-effective than buying them individually.
A great point is that you can try it for free for the first 30 days.
⑦ 辞書機能・検索機能が便利
More than Kindle
If you come across a word you don't know, you can look up its meaning simply by tapping on it.
Unlike with physical books, you don't need a separate dictionary, and the ability to deepen your understanding without interrupting your reading flow is a unique benefit of e-books.
Kindleのデメリット
① 紙の本のような「所有感」がない
Physical books offer the charm of their binding, the feel of turning pages, and the satisfaction of arranging them on a bookshelf.
Some say that because Kindle books are stored as data, it's difficult to get the feeling of 'owning a physical object'. Those who enjoy collecting may find it less satisfying.
② 読める本に制限がある（読み放題の場合）
Kindle Unlimited is an attractive service, but not all books are included in the all-you-can-read offer.
Especially popular new releases and the latest volumes of trending manga are often excluded, so it's common to find that the books you want to read aren't available through the all-you-can-read service.
③ 貸し借りができない（基本的に）
With physical books, you can easily lend and borrow them with family and friends, but books purchased on Kindle are generally tied to an individual account, making lending and borrowing difficult.
④ 専用端末は初期費用がかかる
While you can start for free with the smartphone app, purchasing a dedicated Kindle device requires an initial investment.
The current main lineup is as follows:
| Model | Features | Estimated Price |
|---|---|---|
| Kindle (Standard) | Lightweight & compact, sufficient for text-focused reading | From ¥19,980 |
| Kindle Paperwhite | Waterproof & high-resolution, the best-balanced classic | From ¥27,980 |
| Kindle Colorsoft | Supports colour display, for magazines & colour manga | From ¥39,980 |
| Kindle Scribe | Supports handwriting input, also allows PDF annotation | From ¥72,980 |
For a first device, the 'Kindle Paperwhite' with its waterproofing and high resolution offers a good balance and is recommended as a standard choice.
⑤ バッテリー切れ・故障のリスク
Physical books don't require charging, but there's a risk that Kindle devices may become unusable due to battery depletion or malfunction.
Caution is advised in situations where charging is not possible, such as during long trips or emergencies.
⑥ 目の疲れ方が人による
While E Ink is said to be easy on the eyes, some people may find the screen's response time and display method initially disorienting.
As this varies by individual, we recommend trying out the device in person before purchasing if possible.
Kindleのお得な利用方法
方法① セール・キャンペーンを狙う
Kindle devices are often discounted during Amazon's Prime Day and sale periods, sometimes costing nearly ¥10,000 less than the regular price.
購入を検討している場合は、大型セールの時期をチェックしてから購入するのがおすすめです。
方法② Kindle Unlimitedの無料体験を活用する
初めて利用する場合、初回30日間は無料で読み放題を試せます。
さらに、不定期で「3か月無料」といった大型キャンペーンが実施されることもあるため、公式サイトをこまめにチェックしておくと、お得なタイミングで登録できます。
方法③ Prime Readingとの違いを理解して使い分ける
Amazonプライム会員であれば、追加料金なしで使える「Prime Reading」というサービスも利用できます。
Kindle Unlimitedよりラインナップは少なめですが、すでにプライム会員の方は、まずPrime Readingで読みたい本があるか確認すると、無駄な出費を避けられます。
方法④ 端末購入時は「セット割引」を狙う
Kindle端末を購入する際、「Kindle Unlimited〇か月付き」のセット販売が行われていることがあります。
このタイミングで購入すれば、端末代の実質的な割引に加えて、読み放題も同時にスタートできるため一石二鳥です。
方法⑤ ポイント還元を活用する
Amazonのセール期間中は、購入金額に応じたポイント還元が実施されることがあります。
現金割引だけでなく、ポイント込みでの実質価格もチェックすると、よりお得に購入できます。
Method 6: Return books you've finished promptly.
Kindle Unlimitedでは、同時にダウンロードできる冊数に上限があります。
読み終わった本は返却することで、新しい本をすぐに追加できるため、上限に達してストレスを感じることを防げます。

Who Kindle is not particularly recommended for
△ People who value the texture and sense of ownership of physical books
装丁を眺めたり、本棚に並べることに喜びを感じる方にとっては、電子書籍の利便性よりも紙の本の魅力の方が勝るかもしれません。
△ People who have a clear idea of the books they want to read
If the genres of books you want to read are limited and not included in the unlimited reading service, you may not be able to make the most of Kindle Unlimited. It is advisable to check the available titles in advance.
△ People who want to lend and borrow books with family and friends
For those who frequently lend and borrow books, physical books may be more suitable.
Summary
Kindle is an e-book service with many benefits, including saving storage space, convenience of portability, and good cost performance through its unlimited reading service.
On the other hand, it is important to note that there is no sense of ownership that comes with physical books, and some books may not be included in the unlimited reading service.
The first step to avoid making a mistake is to install the app on your smartphone and start with a free trial. If you find that it suits your reading style after trying it out, you may want to consider purchasing a dedicated device or subscribing to a paid plan.
Find a way to use it that suits you and enjoy a comfortable reading life.
