I can respect why CERO might want extra for ports. Ports can be different, and it will take manhours to check through that possibility which means more money on the payroll. I also find the per-port fee to be a nothingburger: 20,000 JPY or 60,000 JPY per platform for members and non-members respectively. That's ~$133 USD or ~$400 USD assuming 150 JPY to $1 USD exchange rate, or ~$200 USD or ~$600 USD assuming 100 JPY to $1 USD. That is honestly nothing assuming it's a one-time fee to review.
