Yui welcomes you at the table while Aya offers the last gyoza and Ren joins the conversation.

Ren wants the last gyoza. Aya offers it to you.

Aya

ぎょうざ、どうぞ。

Have the gyoza.

You

おなかいっぱいです。

I’m full.

Aya passes it to Ren. He thanks you.
Yui joins in: “Lucky you, Ren.”

Dinner at Aya’s · Yui, Aya, Ren, and you

A whole cast.
One conversation.
And you.

Join Yui, Aya, and Ren around the same table. Follow the conversation between them, find your opening, and become part of their evening.

Everyone has something to say.

Aya is hosting. Ren has his eye on the last gyoza. Yui helps you settle in. Their conversation gives you a real reason to speak.

Your words move the whole scene.

Ask Aya for tea and Ren asks for the same. Pass on the last gyoza and it goes to him. Speak or write your own words, and see how everyone responds.

Small moments.
New beginnings.

Stay for dinner with Yui and friends. Meet someone new. Make everyday Japanese part of your world.

Speak when you can. Type when you’d rather. Take a little help, then make the moment yours.

Your seat is waiting.

Come for the Japanese.
Stay for the conversation.
