Ai Otsuka / Planetarium

A song by Ai Otsuka that became a massive hit as the image song for the drama “Hana Yori Dango,” starring Jun Matsumoto and Mao Inoue.

It portrays the aching feelings for a loved one who is no longer by your side, along with beautiful imagery.

Unrequited love and heartbreak are painful, but the memories left behind never fade.

Whether you tuck those memories deep in your heart and move forward, or immerse yourself in them and become unable to move on, is up to you.

It would be nice to carry them as beautiful memories—like “Planetarium”—while taking your next step.

Ai Otsuka / Peach Petals (Short Ver.)

Spending time with someone you love is so much fun, isn’t it? When you want to keep savoring that happy feeling, put on some love songs! I especially recommend tracks by singer-songwriter Ai Otsuka.

She has songs like “Sakuranbo” and “Kuroge Wagyu Jo Shio Tan Yaki 680 Yen,” but the one I want to introduce today is her debut single, “Momo no Hanabira.” It’s the kind of song that will have you grinning without even realizing it! It’s a heart-fluttering tune that brings back memories of moments spent with the one you love.

Ai Otsuka / Sakuranbo (Short Ver.)

A pop tune released in 2003 as Ai Otsuka’s second single, still sung by people of all ages today.

While it has an energetic, powerful image, this song is actually a cute love song that expresses the excitement and bounce of being in love and feelings that lead toward the future.

The lyrics overflow with the sentiment of “I just love you so much,” no matter what happens.

It might be unrequited love, but it’s a powerful song that gives you the magic to enjoy romance by making your heart flutter for the person you adore.

Ai Otsuka / Clingy Lover

A masterpiece that portrays the bittersweet heart of a girl who can’t be honest in front of the one she likes.

Released in March 2004 as Ai Otsuka’s third single, this song is also well known for its use in Sato Pharmaceutical’s “Stonarhini S” commercial.

The lyrics capture the feelings of a clumsy girl who puts on a brave face even though she really wants to be affectionate—resonating deeply with the gals who blazed through the Heisei era.

The gentle piano tones and Ai Otsuka’s emotional vocals vividly express the wavering feelings of love.

It’s perfect for when you want to confess your feelings to someone you adore, or when you want to show a touch of endearing charm at karaoke.

It feels fresh to warm up and cool down feelings of love in a microwave.

The boy I like is my childhood friend, and even though I’ve hidden my feelings and sometimes cheered on his romances, deep down I want him to look at me.

It’s a cute unrequited love song.
