Technologies used: Leaflet (frontend) Turf (Geojson generation and Voronoi generation)

I noticed that my neighborhood is all Lawsons, so I got the location of all Conbinis and ran some basic analysis to see if these pockets of brand territory are common.

I haven't worked much with web frontends before, so feedback is welcomed. I also have some ideas to maybe expand upon, like making the territory calculations based on streets and other geographical features rather than just beeline distance.

The site isn't tested too much on mobile yet, but should be ok.

Currently the frontend code and geojson files can be found at the public repo: https://github.com/kikkia/ConbiniWars. I will upload the backend code soon as I am cleaning it up and reorganizing it.

I appreciate that the map renders the regional name and character set of the territories

This is cool. One of the things I miss most after my trip to Japan is 7-Eleven/FamilyMart. So many nice snacks and drinks, and you never need to walk more than two minutes to find a store. I liked the onigiri a lot.

At first I struggled to make sense of the numbers in the circles. Surely there can't be 10,110 locations in a space the size of the SF Bay area? But yes, yes there are...

For anyone else whose only experience with Japanese convenience stores is the Yakuza games wondering which one Poppo is supposed to be:

> Poppo appears to be based on two of Japan's leading convenience store chains, Lawson and FamilyMart, as evidenced by most of the outlets in the series being placed in locations that correspond to branches in the real world.

That’s the OpenStreetMap default.

On my recent first trip to Japan, I couldn't believe the number and quality of 7-Elevens/Family Marts/Lawsons.

You're never more than a five-minute walk from one in Tokyo, and they've got good stuff.

Japan is _dense_ in the major cities. As someone from London, not exactly a quiet village, it's on a completely different level.

Interesting! 7-Eleven, Family Mart and Lawson are all in Thailand too, but I think 7-Eleven is overwhelmingly dominant, eg on my street in a 100m radius there were three 7-Elevens to just one FM and one Lawson.

Update: some stats, it's not even close... ~200 Lawson in Thailand, ~200 Family Mart (now Tops Daily), and 14,000 7-Elevens. Guess I just spent a lot of time in places with Lawson and Family Mart. This also means the 7-Eleven population density is about the same in Japan and Thailand, around one per 5k people.
