Message: This "Structure Karuta" began as a project to help everyone—whether they excel at organic chemistry or struggle with it—enjoy the learning process. During development, we received valuable advice from Professor Seiji Esaki of the School of Pharmacy at Osaka Ohtani University. This app is part of an educational research project and is supported by JSPS KAKENHI Grant Number 23K02725. I hope that through this app, many people will become familiar with chemical structures and find a bridge to further learning.
