Thanks for your suggestions, Dale, i appreciate. I wouldn't go that far to say they are a totalitarian system, as if it would be so i wouldn't live here. The problem is that whenever they face an issue of this type (drone, careless photography etc) they tend to go for the most effective way regardless of the majority of people doing their thing properly and safely. In the case of drones, things were fine until 2015, when a weirdo landed a drone with radioactive sand on the roof from the Prime to protest. Few months later, government hit with the infamous Drone Laws and here we are, with nowhere to fly, not even parks. For the photography ban in Kyoto, it's more of a local law, but i saw along the years "no pictures" shields/posters pop all around Japan's public places. Why ? There are 2 reasons for that which i will explain, but first let me tell you what i'm doing here.
I have a website (currently in development) since 2009, and circa 2.4TB data (photo/video) waiting to be treated and published. I visited around 85% from Honshu (the main isle), and went to Shikoku, Kyushu and Okinawa, only Hokkaido i didn't visit yet, which is planned for next month. So basically, i went almost everywhere in Japan, and focus mainly on landscape/architecture/street photography.
The 1st reason why photography ban increased in many places is because of retired Japanese hobby photographers. Sounds weird ? Let me explain. Those guys have nothing to do all the day, and squat temples, gardens etc for days with very expensive and voluminous material (we are talking here from 50-60cm white/grey lenses) disturbing visitors as they occupy the best viewing spots for hours without caring about anybody else (Japanese old people have often a... how can i politely say ? slight selfish way to behave towards others). Managements first tried it the smart way : they forbid tripod use, but it didn't help much : they still came and occupy spots for hours trying to get their precious shots from an insect on a leave from the tree 30m away on the other side of the garden... (did u felt some irony in my words ? you're completely right ^^). So as a result, they simply forbid pictures to maintain fluidity within the premices so that visitors can walk through and get out asap. I cannot count how many time, wherever i visited in Japan, i had to wait over 30 minutes to access a spot to take within a minute a dozen of pretty nice shots from something. That's also why they tend to put everywhere staff shouting in your years (politely but loudly, lol) to continue to go forward.
The 2nd reason why photography ban increased, is the behaviour of some tourists itself, especially from Asia, which became a nuisance all over the country. Fact is that economically, the government wants to increase the amount of visitors for financial reasons, but locals suffer a lot from it, especially in Kyoto. Now, it will be hard for anybody to understand how fragile and special some places are, as Kyoto for example, if they didn't went there. This is the reason why i stopped visiting Kyoto every year as i used to do for years. Locals had no choice with government promoting Japan and willing to get more and more visitors, so they did what they thought was best : they started photography ban, not only in temples or gardens, but also in streets. That's how in October 2019, the most famous area of Kyoto introduced photography ban in it's streets. In Japan, laws are different, so even a street might belong to a private owner and not to the municipality. I remember hundreds of occasions where i saw some asian tourists entering private property, opening the garden door to take some selfies standing on the grass and flowers, or hugging some sacred divinity statue, putting some soda can on its head, or grabbing the kimono of a geisha to stop her and having a photography, climbing over the rail of a 600 years old temple to take a picture on the wooden floor with muddy shoes... (this is all real, saw it with my own eyes).
This ban punished us (locals, expats and Japanese, respectuous photographers etc) for the behaviour of a few, and thats where i tried to make my point : there is one holy principle in Japanese society called 和 (wa) which means approximatively "harmony", and it overrides anything else. To preserve the "wa", they're willing to ignore the needs of the "good guys". No trouble with an anti-foreigner potential polemic : ban is for everybody, period. I faced this many times already, and it's a point i understand but never liked, like tatemae (another principle also to avoid any trouble).
However, after this long explanation which i hope wasn't too boring, back to the photography discussion. I must say, i'm only moderately interested in dark skies photography, but i enjoy doing night photography as i have pretty good material for low light conditions (D750 + Tamron 15-30mm f2.8/Nikkor 35mm f1.8). Similar to you, the drone was also meant to add a new vision to my shootings, and i intended to try the fantastic new timelapse system which the
MA2 proposes (8k hyperlapse !). What annoys me most in this whole story is that except indoor expensive places, crowded as hell, there is not much possibility around here as even the white marked fly zones of the map i noted, became local regulated no-fly zones within the last years (i checked them individually, and i'm not really wondering about it, as with so few possibilities and such a terrific ban, i guess every pilot went flying there until it became a nuisance for the locals). I guess i'll have an expensive and 2h train trip each time i want to train...
