How can I improve this notice board nomination?
Currently, I just have an English description that matches the Japanese title. This is pretty common in Japan, especially when there's not a lot more to say about something. I've tried this with a full Japanese description, explaining the cultural aspect of the board, but I think it's probably a given to most people what it is anyway.
In the supporting text, I've linked to https://community.wayfarer.nianticlabs.com/discussion/2754/are-information-boards-or-map-boards-eligible#latest more recently, for examples of other accepted notice boards. I've also linked to the older Ingress AMA as well.
My supporting text is all in Japanese, but basically I try to explain that notice boards with cultural or historical information are great candidates, and boards with nothing but business flyers would not be good. But what it always comes down to, is I don't think Japanese players believe any of this information. There are some Japanese-only forums where lots of players have basically taken it upon themselves to decide what is allowed and not.
I know most people can't read Japanese here, so you might not know what all the flyers are on this notice board, so let me try to explain some of them. The girl in the blue and pink one is holding a box that says "Vote" and as you might imagine, this is information about an upcoming election, and where and when to vote. There is more detailed information in the bottom right corner in a blue flyers which is also about the election. Below that girl is a flyer for Tanabata (the Star Festival). Unfortunately, due to Corona the festival was cancelled this year it says. The very large poster on the right half is about a post-WW2 recovery historical exhibition, involving the local area.
The content of this notice board changes frequently, but it's always cultural or government information, and is an important source of such information for people in the area. It's on a street that is mainly used for walking towards the train station. Our actual city hall is not nearby (maybe 5 stations away) and nobody would regularly visit city hall to see information like this, which is why local town associations will spread the information on notice boards such as this, in places with heavy foot traffic.
I'm not sure what else I can do to improve this nomination. I keep getting rejections such as generic store or restaurant, obstructs emergency services, flagged for explicit content, photo is tilted or upside down, flagged for including personal information, appears to be a body part, etc... and clearly none of these reasons are true at all. The notice board is clearly visible on Street View and honestly I believe it to be quite a bit nicer and mroe well maintained than a lot of notice boards I've seen accepted elsewhere.
