I've a Japanese friend coming to the European Union, land in the UK and depart back to Japan from The Netherlands with flights from UK to Portugal and from Portugal to The Netherlands.
I know that Japanese nationals can request a tourist visa on landing but I do not know how it will work when my friend fly from the UK to Portugal and from Portugal to The Netherlands.
What kind of tourist visa does my friend needs to request when landing in the UK to be able to later on leave the UK and entry Portugal and then The Netherlands?
My friend will be staying 4 days in each country, (4 days in the UK, 4 in Portugal and 4 in The Netherlands) but will be attending a conference in the UK. In Portugal and The Netherlands will be solely for tourism.
