The prefectural capital of Iwate was where the shinkansen (on which I had had the amazing 30 ingredient ekiben!) took me. Being some 3.5 hours up north from Tokyo even on the super fast train, I found the temperatures noticeably cooler there than in the Japanese capital, never mind Hong Kong -- and the red leaves of autumn evident in many parts of the town/city, including from my hotel room window as well at the old castle grounds in Morioka which has been conveted into a public park known both as Iwate Park and Morioka Castle Ruins Park.
All this made for some nice visuals -- and quite the change from the previous time I had been up in Tohoku: back in May 2019, when I was pleasantly surprised to come across still blossoming sakura (in Sendai and Hiraizumi). And while I know there are people who go gaga over sakura, I must say that I adore the sight of koyo (autumn leaves) -- and catching sight of some of them on this recent Japan visit was a nice bonus; something which I didn't really expect to do in view of the leaves of the trees at Shinjuku Gyoen that I viewed on the same trip (and, in fact, just the day before!) having been pretty green for the most part! :)
