万博記念公園
Also known as Banpaku Park, Osaka Expo Park, Tower of the Sun, Banpaku
A green sprawl north of the city centre, anchored by Taro Okamoto's Tower of the Sun — the four-faced statue left over from the 1970 World Expo. The locals call it Banpaku. One vlogger admits the tower 'terrifies' him; the other notes the on-site ferris wheel is the tallest in Japan and comes with kotatsu cabins in winter (sake and oden included).
In winter, ride the ferris wheel for the kotatsu-and-sake setup.
