How long does it take to visit the whole of Japan? how much is it? Any suggestions?

Tokyo, Osaka, Kyoto, Nara, Kobe and Nagoya in Honshu Island are short of 15 days, Hokkaido is short of 7 days, Fukuoka, Nagasaki, Kumamoto, Kagoshima and Miyazaki are short of 10 days, Shikoku is short of 5 days, Ryukyu and Okinawa are short of 3 days * * 40 days. If you play 800 ~ 900, the traffic will be more than 100, with 281,000 * * a day, divided into five trips, with a round-trip air ticket of 40 million yuan for each trip, and a 40-day trip to Japan with 65,438+million. You can choose your favorite city and recommend Tokyo, Osaka and Kyoto. If you buy a ticket one year in advance, go back and forth to Osaka about 1400, and then leave Osaka. Osaka recommends Universal Studios, Tokyo recommends Disney, and Okinawa is more distinctive. Tokyo prefers shopping, Osaka prefers having fun, and Okinawa prefers sea view. You can choose one of the major cities recommended above.
