I've been stuck here in the north of England

for a year and we can't even go down to London. Holland is just across the water (think Osaka to kyushu by Ferry), but we can't leave the area let alone travel to another country. I'd love to be back in Japan for the cherry blossoms and warmer weather. My goal is simple: Vaccination will free me, release me and the world is my oyster(very,very delicious here,by the way).
Note-"oyster " is an idiom meaning "treasure box"
