Ensure your IDP or Japanese translation is valid. Get a Japan SIM card or WiFi device for navigation. Download offline Google Maps and campervan apps. Bring cash as many campsites and fuel stations don't accept credit cards.
Taiwanese travellers need a Japanese translation (available from Taiwan motor vehicle offices or Japan's JAF). Japan strictly enforces traffic laws—speeding and drink-driving fines are very high. Campervans are typically limited to 80 km/h (expressways) and 60 km/h (regular roads).
Japan drives on the left. Expressways have strict speed limits and toll stations. Use an ETC card for automatic payment and discounts. Note that many road signs are in Japanese only. Take extra care on mountain and narrow roads with a campervan.
Michi-no-Eki (roadside stations) are a campervan traveller's best friend—free parking, toilets, and local products. Note: they're not official campsites, and extended stays may be discouraged. Large shopping centres and onsen facilities often have campervan parking too.
Japan's onsen culture is a highlight of campervan travel. Many campsites are near onsen facilities (¥500-1,500). Remember onsen etiquette: wash before entering, don't use towels in the pool, tattoos may be refused entry. Use the 'Onsen Tengoku' app to find nearby onsen.
Essentials: IDP/Japanese translation, cash, SIM/WiFi, chargers, rain gear. Camping gear: sleeping bags (some vehicles don't provide them), utensils, seasonings, garbage bags. Recommended: small fan (summer), heat packs (winter), slippers, swimwear (for onsen).
