The Netflix Series "Grass Heart" was Produced Over 5 Years
"Grass Heart" is a musical youth love story based on the novel of the same name by Mio Wakaki. Takeru Satoh, the lead actor and co-executive producer, said that he encountered the original work when he was in his 20s and was particularly attracted to the character Naoki Fujitani. Just like Naoki Fujitani in the play, he personally approached the actors and gathered the performers with his enthusiasm, and it took more than five years to realize the film.
Commitment to Music that Colors the Story
An essential part of telling the appeal of "Grass Heart" is the music that envelops the story. In this work, original music is created to match the emotions and situations of the characters. The products will be provided by artists representing the Japan music scene, such as Yojiro Noda of RADWIMPS, Taka of ONE OK ROCK, and Yohei Kawakami of "Alexandros".
In addition, the cast members who play the band "TENBLANK" in the play spent more than a year practicing their instruments before filming began, realizing realistic performance scenes. At the same time as the drama's release, he also made his debut as an artist in the real world, making fans enthusiastic.
Synopsis of "Grass Heart"
Akane Saijo (Yu Miyazaki) was kicked out of her band because she was a woman and was about to give up her dream of becoming a drummer. She receives a phone call from the genius musician Naoki Fujitani (Takeru Satoh). The content is scouting for the new band "TENBLANK" led by him.
At the place where she was called, Akane met the charismatic guitarist Hisashi Takaoka (Keita Machida), who has an overwhelming presence, and the keyboard player Kazuyuki Sakamoto (Jun Shison), who is a music enthusiast and also works on writing and arranging. With Fujitani's one-of-a-kind songs and the passionate performances of the unique members, TENBLANK will quickly take the music scene by storm.
But the road is far from smooth. Although he is conflicted between his dreams and reality, he overcomes it with his friends. Not only as a story of the band's growth, but also as a love pattern depicted around Akane.

"Glass Heart" Collaboration Café Visit Report
From here, we bring you scenes from the previous collaboration café. We visited the TOWER RECORDS CAFE Osaka Station City store.
Admission is on a rotational basis, and advance reservations are recommended. Another nice point is that you can get a sticker as a reservation bonus.

All of them are specially designed to be related to the scenes and songs of the work, and the lineup tickles the hearts of fans from appearance to taste. Here is a list of the menus I actually ordered.
Food: Momoko's Chicken Curry 1,490 yen
Reproduce the famous curry of the café run by Akane Saijo's parents' house. Many people must have seen the work and thought, "I want to try it!" This sweet butter chicken curry is also recommended for those who don't like spicy food. If there was really a café, it would be a taste that would make you want to become a regular.
Sweets: Glass Heart 1,490 yen
The fluffy pancakes that bear the title of the work are served with sweet and sour strawberry sauce. When you take a bite, the sweetness and acidity spread out that will make your heart pound.

Sweets: Melody and Crystal 980 yen
A drink inspired by the song "Melody and Crystal" that was released in advance from the work. Like the song, it is based on a fast-paced blue cider, and is specially designed with the addition of white balls, nata de coco, and jelly. It looks refreshing and is satisfying to drink.
Drink: TENBLANK Latte(CHAI) 780 yen
An iced chai with the "TENBLANK" logo drawn in latte art. It is a cup with a slightly sweet and spicy flavor that is addictive. There is also a BLACK version, which is unsweetened coffee based and has a mature taste.
