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.
