幼いころからファッションが大好きな朝宮日向ちゃん🎄

She learned about the profession of ``stylist'' when she was in the third grade of elementary school, and since then she has been aiming to become a stylist and even went to a vocational school.💡

アイドルに憧れるようになったのは、「乃木坂46」の冠番組を見て衝撃を受けてからのこと📺

I auditioned for the Sakamichi Group five times and even though I failed all of them, I didn't give up and took on the challenge with determination for the last time, which was the IDOL3.0 PROJECT.💪

食べることも大好きで、特にオムライスが大好物🍳

According to the person himself

“I think I know more about new product information at convenience stores than any of the other members.”

"I'm always thinking about food somewhere in my head, and eating is like living!"

Her strong passion for food is also very endearing.👀💕

Kotori Ayase (formerly Kotori)

Kotori Ayase likes the anime ``JoJo's Bizarre Adventure'' and honed her drawing talent the more she attended vocational school.🎵

Besides that, her charm is that she has many hobbies such as singing, watching movies, watching anime, and playing musical instruments.✨

It seems like her dream is to one day make Rain Tree goods using her own illustrations, so she's looking forward to that day coming🤍

Tsumugi Ichihara (formerly: Ichi)

Rain Tree members

  • Name: Tsumugi Ichihara
  • Old activity name: Ichi
  • Date of birth: November 17, 2004
  • Age: 20 years old (as of June 12, 2025)
  • 出身地:千葉県
  • Blood type: B type
  • Height: 158cm
  • MBTI: INTP
  • Penlight color (member color): Yellow x white
  • ⭐X:@ichiharatsumugi
  • ⭐Instagram:@ichiharatsumugi
  • ⭐TikTok:@1hara_tumug1

Tsuki Ichihara has a unique sensitivity and a warm heart.💖

At first, she wanted to be an actress and took acting lessons, but

"I love idols"

"I'm going to become an idol, and on top of that, I'm going to become someone who can act like an actress."

I stuck to that feeling and went on to become an idol.🌷

In "IDOL3.0 PROJECT", he will show off how he can utilize the chef's license he got in high school to convey his individuality!

He tried cracking walnuts with his head, peeling daikon radish with air, and cutting green onions.🍳

Although he is usually a goofy character, he is actually the type of person who does not show his efforts to others, but is a hard worker who practices secretly and proves it with results.💪

He also has a caring side to his members, and sometimes serves them home-cooked meals out of concern for their health.♡

This gap is also one of the reasons why it is loved by fans.♬

  • ⭐TikTok:@endo_rino

Rino Endo leads Rain Tree with her 11 years of dance experience!

The reason I wanted to become an idol was because of my favorite anime “Aikatsu! I admired the main character, Ichigo Hoshimiya.🍓

It seems that she was moved by seeing her grow from a "no-good" start to a top idol.✨

Endo Rino-chan is usually a "spoiled character" and often clings to older sister members.💫

She is a very girly member who has a lot of skinship, and her voice, the way she talks, and her casual gestures are cute.🍬🎀

On the other hand, dance, which I have been learning since I was a child, is the best way to express myself with confidence!

Many fans are becoming fascinated by the gap between the atmosphere that changes drastically depending on the song and her usual appearance!

小学校1年生のときに自己紹介で「大きくなったらアイドルになりたいです」と夢を語っていたほど、幼い頃から女性アイドルが大好きでした💕

ファンとしてアイドルを応援していたのですが、そのうちに憧れの気持ちが強くなり、「自分もアイドルになりたい」と思うようになりました💡

During his time with ``FINALIST,'' he also had to temporarily suspend his activities to prepare for university entrance exams.

Although there were times when she felt anxious and anxious, she gradually became able to balance her studies and idol activities smoothly.📚

Katase Maka-chan is the type of person who speaks loudly in front of people, and is sometimes said to have the loudest voice among the members.👀

A serious, strong-willed personality and a cheerful presence are one of Rain Tree's essential charms.🌷

芸能界に憧れたきっかけは、小学5年生のときに観た映画『ビリギャル』で、「キラキラしている世界って素敵だな」と思うようになったのだといいます🎬

そんな憧れの想いを胸に、高校の学園祭でダンス部のメンバーとしてパフォーマンスを披露した経験から、本格的にアイドルを目指すように🌟

Kato Hiiragi-chan is a reassuring presence for Rain Tree, as she is able to objectively view the group and express her opinions when necessary.💡

As of June 4, 2025, I have suspended my entertainment activities due to poor health.

Rain Tree's "black hair bob" person, Kurosawa Keiko!

I have loved singing since I was in kindergarten, and I was shocked by the MV for Keyakizaka46's "Silent Majority" when I was in elementary school, and I began to strongly admire Yurina Hirate.✨

小学2年生から5年間続けたチアダンスでは、全国大会に出場するほどの実力者!

チアダンスで培った、ステージ上での表情管理もバッチリです🎀

Kurosawa Hekoi-chan is often referred to as a "baby", but the way she is strict and stoic towards herself is very mature and attractive.✨

見た目は清楚でお嬢様っぽい印象だけど、実は体操・バスケ・格闘技までこなす本格派のスポーツ女子🏀

I remember watching the movies ``Mission: Impossible'' and ``Charlie's Angels'' when I was little and thinking, ``I want to fight, too!'' and started learning martial arts.💥

She usually has a soothing and calm atmosphere, but when she gets excited, she can suddenly go into a playful mode, and many fans are thrilled by this gap.💞

In fact, she is also a ``current graduate student'' and is loved for her stoic attitude of continuing to study hard even in between her busy idol activities.✨

Rain Treeの中でも「涙もろさ」No.1の永瀬真梨ちゃん💧

感動や嬉しさ、悔しさ…どんな感情もすぐに涙に変わる、繊細でまっすぐなハートの持ち主です😭💘

I became interested in idols due to the influence of an older sister who likes Nogizaka 46, and when I went to see Hinatazaka 46's live performance, I dreamed of ``I want to become an idol who can move many people!''🌈

As an idol, she is the type who “reveals her true self” and is loved by her fans for her attitude of expressing her feelings without embellishment🥰

将来は、白石麻衣さんや小坂菜緒さんのように、モデルや女優としても活躍したいという夢も✨

その熱意と感性が、永瀬真梨ちゃんの魅力をさらに輝かせてくれそうです💫

“If someone is in trouble, I want to support them.”

"There may be a feeling that because she's older, she has to act like an older sister."

That's what it says.💡

However, she is actually the youngest of three sisters, so she admits that she is a ``big sister character''👀!

Umi Yoshikawa actually worked as an esthetician before becoming an idol.❣

I have always wanted to be an idol since I was in elementary school, and have tried many auditions since I was in college.🙏

I decided to apply for the IDOL3.0 PROJECT, which was close to the age limit, as my "last chance" and achieved my dream.🌟
