This is off topic but actually Kobo is owned by Rakuten, a Japanese company.
As a result, they have strict policy in Japan.
I can't change countries, or "travel" as you say. My Japanese credit card is linked to my Japanese address. There is no alternative payment method such as paypal. My IP always redirects me to rakuten.kobobooks.com. It is impossible for me to open kobobooks.com
I don't want to rain on your parade, but this "traveling" might be a temporary thing, and Japanese may very well decide to enforce order on other Kobo sites as well.
I hope they don't though
