June 29 is observed by some as Beatles Memorial Day in Japan. The date marks the anniversary of the Beatles’ first appearance in Japan in 1966 when they touched down at Haneda Airport  in the middle of Japan's monsoon rainy season  and played the next day at the Budokan martial arts center in central Tokyo, the first of five concerts  they would play on that tour.
This year on June 29 the hashtag ビートルズ記念日  (Beatles Memorial Day) trended on Japanese Twitter, as many fans shared their memories and appreciation of the Beatles.
The 1966 visit by the Beatles to Japan is regarded as a turning point in Japanese postwar culture. Hoshika Rumiko, the first Japanese journalist  to carry out an exclusive interview with the Beatles in London in 1964, remarked  in 2016 on the 50th anniversary of the first visit:
The Beatles were only in the country for a little under five days, but that short visit was enough to change public opinion totally. People soon realized that they had no choice but to embrace the Beatles.
Many of the giants of Japanese industry today came of age when the Beatles first came to Japan in 1966. As reported by Nikkei Asian Review , according to Ryuichi Isaka, president of retail giant Seven & i Holdings, the Beatles’ music is “more of a universal language than English.”

Good morning! ♬ It's Beatles Memorial Day in Japan. 🎶🎸 It's been 51 years since they came to Tokyo.
Today, Beatles songs are still sung in karaoke bars in Japan as well as in English class  in Japanese middle schools. Beatles kitsch still survives as well.

It's Beatles Memorial Day today. We love the Beatles at our house. I have no idea if this Winnie the Pooh doll is supposed to be John Lennon or not.
And, like any fans, Japanese people make pilgrimages to special spots identified with the band.

皆さん、おはようございます。 今日は『ビートルズ記念日』です。 1966年のこの日、ビートルズが初来日しました。 お友達の中には映画けいおん！の聖地巡礼でロンドンに行かれた方がいますが、何時か自分もアビーロードを歩いてみたいものです。 って、去年も同じ事呟いていたな （＾ ＾； pic.twitter.com/EDmeu4uk0P

Good morning, everyone. Today is Beatles Memorial Day. On this day in 1966 the Beatles first came to Japan. The characters from the movie K-On! made a pilgrimage to London, and walked on Abbey Road. We did the same thing last year.
And, as always, some businesses will try to capitalize on fandom to market themselves, such as this Tokyo ramen shop.
ということで本日もお待ちしております♡ pic.twitter.com/meLCTBXyG6
