brick-and-mortar bookstore; physical bookstore
Used to distinguish a physical bookstore from an online bookstore. Often contrasted with ネット書店 or オンライン書店.
I mostly buy online these days, but sometimes it's fun to browse for books at a physical bookstore.
Compound of リアル (from English 'real') and 書店 (bookstore). Coined to contrast with online bookstores.
