Important Notice
Please be informed that the ICHA2023 Hiroshima will be held EXCLUSIVELY IN-PERSON (no online participation) and will NOT accept payments through PayPal.
The conference has been changed to 'in-person' attendance only because of the global improvement in COVID-19 restrictions, to reduce the high cost of online participation set-up (only a few online participants are currently registered) and in addition due to the global increase of food and energy costs.
We apologize for the inconvenience caused and look forward to seeing you in person this November, in Hiroshima.

There are several websites announcing conferences with the same name as ours (ICHA 2023). Some of them will be held in Kyoto, Tokyo or other cities outside Japan. These conferences have absolutely no-relation with us. Please stay tuned with our genuine website (
https://icha2023.org). We are looking forward to seeing you in Hiroshima in November 2023!
