Hey, I know this place! I have a friend that used to work at Huis Ten Bosch. I've never gotten the chance to go myself but it seems like it would be a really cool place to visit. I can imagine in the spring the flowers are really awesome like this photo as well so now is probably the best time to check it out. I know the do illumination events and other stuff as well so that'd probably be a good idea for dates or even just for some casual fun with friends. I think they have boat rides as well. To be fair there's probably not much they don't have I guess the park is supposed to be pretty large. Nagasaki is a little far from Tokyo for a day trip but maybe this summer I can get something worked out. Would really love to visit.
