Ideal Year Calendar through Japan
As an enthusiast traveler in Asia, I have experienced it all. From going to crowded places in the high season, such as Tokyo and the Kansai region, to experiencing festivals in the lesser-known areas. Below is my ideal travel plan in Japan, to avoid the crowd while experiencing the vibrant festivals and the season changes.
New Year & Ending of the Christmas season in Kanto: The Christmas decorations still light up in Tokyo until the 3rd week of January. And, the flights and hotels are more affordable making it perfect for day trips around Tokyo and discovering Kanto.
Winter hot spring bath called Onsen & First Blossom in February: Atami Plum Garden (Chubu seaside near Hakone) & Yamanashi nature sightseeing around the Fuji 5 Lakes and Hakone.
Cherry blossom viewing in late March: Seishindaitokushoutokuhi (Chugoku Miyajima island with deers), Hill of a thousand cherry trees (Chugoku seaside near Onomichi and Hiroshima), Nagarekawa Cherry blossom trees (Kyushu cherry blossom festival)
Experience Hokkaido off-season, ski, onsen, and sightseeing without the spring rain but snow. Or, Tohoku nature sceneries with the late Cherry Blossom Festival at Hirosaki Cherry Blossom Festival (3rd and 4th week of April).
May is the after Golden Week, meaning Hakone and Kawaguchiko will still be crowded. But, the North of Chubu such as Gifu’s onsens, Shirakawa-gō, and Gokayama villages, and seeing a part of the Japanese Alps is worth it!
It is difficult to avoid the rainy season, but Okinawa’s weather in May and June is pleasant with light rainfalls. Hot enough to enjoy swimming, and humid enough to see the vegetation strive. Knowing typhoons occur frequently in August and September, late June should be the perfect in-between period.
July is the start of summer with major festivals all across Japan. Enjoy Kyushu’s Hakata Gion Yamakasa on July 1st, and the multiple other festivals in mid-July. Or, you could find a quiet seaside town. Finally, Mt. Fuji could be climbed in perfect conditions in July. And, the Japanese Alps are also a popular destination at that time with the summer blooms.
August is the peak of the tourist season with the highest summer temperatures and many festivals. To avoid the crowd and heat, a quiet town visit in Shikoku or Tohoku is perfect. Shikoku is near Kinki and Chugoku where the most vibrant August festivals happen. It is also well-known for its hiking and sea scenery up hills. Tohoku is incredibly diverse in August with the 3 Great Festivals (Nebuta, Kanto, and Tanabata).
When summer’s excitement tones down, it is time to visit Kinki properly without the heavy crowd. Enjoy the mountain stream and restaurants near Kifune-jinja in Kyoto. Eat extravagant Japanese food around Osaka, and bow to the deers in Nara. Other popular spots in Kansai are the Ine fishing village, Amanohashidate, Kinosaki onsen, and Tottori Sand Dunes.
October’s warm weather is perfect for visiting Okinawa and Kyushu. The outdoor Hakata’s food stalls called Yatai are a must-try. There are also plenty of landscapes to discover.
Fall foliage is the best in November. Hokkaido (from the beginning of November) and Chugoku (from mid-November) offer 2 different vibes while having pretty red maple trees and hills. One best activities is bathing in a hot spring!
December has quite a high hotel and flight price tag compared to the volume of tourists. This is mainly because of domestic tourism. But, this is a nice period to visit the popular cities. With the mild temperatures and Christmas feels, Tokyo and Osaka can be so fun!
