Okay so here is my version of Dsp going to japan.
First off he would have to forced to, as in his fat whale of a wife will insist or in the best case scenario his parents died and he got an inheritence and hes just spending like there is no tomorrow. Now assuming he decides to go, then comes the actual process of booking the flight, depending on how much money(not spend on hogans) he has, he will either go 1st class because hes a """""hard worker""""" or willl try to go the cheapest(cause he still needs his hogans). Also he will complain about the process and probably do some vlog explaining how X company are dipshits and didnt cater to HIS needs. Also he will complain about the long hours and why there isnt a direct flight to japan "Guys japan is behind us, why cant we just fly west and get there"
Now he has arrived to Japan(shit hole that you couldnt pay me to live and would nuke a 3rd time if given the option) Now idk much about the customs there but ill assume dsp will break most of their etiquette and customs. He will waddle along with his whale wife(which should be careful of incoming harpoons) and go to the nearest hotel and try to make a reservation, will complain in a later vlog about said hotel or how the person in the lobby doesnt know english. Assuming he will leave the hotel, i believe he will go to the tourist traps, probably wander into the wrong alley and get mugged(aka Gunt in Portugal) while his wife is too busy dodging harpoons to notice. He will then go back to the hotel waddling, make a vlog and complain about how shit japan is and that he is never coming back and proceed to spend the reminder inside the hotel ordering the equivalent of doordash there or going to the nearest mcdonald just to get a sense of familirity. Then he will come back to his wahkando make a video about the trip, complain and beg because the trip was unnecessarily expensive and he needs the tips to pay for billls and then we go back to the same cycle.
