If you’re visiting Japan but somehow is too broke to shell out extra money for the Lonely Planet guidebook, you may be glad to know that the Japan National Tourism Organization (JNTO) provides an in depth 48-page guidebook on Japan. Although it doesn’t provide accommodation and restaurant recommendations, the Japan Guide gives a great overview of the culture, currency, transportation, map, and must-see sites throughout the country. Chock-full with images, this PDF makes a great read during your flight into Japan!
