The Japanese you need for a trip to Japan, then the JLPT N5. TRAVEL Eleven short modules in the order a trip happens: arriving, the konbini, restaurants, hotels and ryokan, trains, shopping, health, being polite, sights, reading the city. Each phrase comes with what staff say back and how you answer. KNOW-HOW Fifty quick cards on how Japan works: train types and station numbers, IC cards, the last train, tipping, shoes, onsen etiquette, emergency numbers. Each one has a one-question check.
