Warm greetings from the ICHO 2025 Secretariat.

We are pleased to inform you that the early registration deadline for ICHO 2025 has been extended to August 8, 2025 (KST).

This will be the final extension, as the ICHO 2025 "Organizing Committee has decided to extend the early bird period slightly to allow more researchers to participate at the discounted rate.

After completing your early registration, please proceed with the payment through the online payment system.

· New Deadline: August 8, 2025 (KST)

We look forward to seeing your valuable research shared at ICHO 2025 to welcoming you in Seoul.
