I will be traveling to Japan for the 2nd time during the CNY period in February for 10 days 9 nights. I have been to Tokyo, Osaka, Kyoto, Nara and Kobe. This time I will be flying to Nagoya because the Airasia X airfare was really cheap at 199 one-way. Is there anything to do in Nagoya? What other parts of Japan should I visit? Should I consider going south at Fukuoka, Hiroshima, Nagasaki, Kagoshima or north at Sapporo (Hokkaido)? Is it practical to take a domestic flight to Fukuoka from Nagoya and then take a train to visit Hiroshima and then fly to Sapporo and then fly back to Nagoya to catch my flight back to KL? For seasoned Japan travelers, please share with me your suggested itinerary.
