Conbini Wars – Map of Japanese convenience store ratios

These Japanese YouTubers decided to play a game, they got off a station earlier than their home and to walk home from there, but whenever they pass a Conbini they'd have to pick 6 items and roll a dice and buy that item from the 6. There's a lot of stores...

Often, several stores belonging to the same chain are located in close proximity to each other so that goods can be distributed more cheaply and frequently. This strategy is known as dominant policy (ドミナント政策, dominanto seisaku).[1]

This is great, but it doesn't differentiate between "Natural Lawson" and "Lawson", which my partner and I have dubbed "Unnatural Lawson".

I'd love to see this for Taiwan. I'm here now (on my Nth trip where N >= 11), and my impression is that 7-11 is the clear winner in all the cities I've been to, followed by Family Mart and then some stragglers like Hilife and OK Mart (it's ok).

My personal favorite is probably Family Mart, because they have multiple very delicious vegan rice balls to choose from.

Pretty cool stuff! Side note, it’s always fun to see Japan-related content getting to the front page around this time, as the people in NA are asleep. Would be curious to see HN userbase %s by continents.

In the US, 7-11 has started selling Japanese style egg salad sandwiches. I haven’t been brave enough to try one yet.

What’s the source for combini locations?

I’ve actually been interested in that data for a back burner project for some years now.

I would really like to know some stats about the Voronoi cells, like average size, largest and smallest...

Here's a similar analysis for Hong Kong: https://khwongk12.medium.com/7-eleven-vs-circle-k-5964b8f008....

I live in Japan. This is great! Though with all the overlay it’s hard to pinpoint my neighborhood. A gps loc button or the ability to temporarily turn off the colors would help! Thank you for making such a fun thing :)

This is fun, but I would separate specialized outlets. For example Lawson and Lawson 100 are not the same.

I wonder if this information would be a useful addition to a geoguessr player’s toolbox.

A few years ago, I was in Wroclaw and it was full of convenience stores.

Where I stayed, you could go to a store and from there see the next one already.

Nice concept but struggled to find my area. Short of search or using my location it would be nice to have a line overlay (lines which go underground are obscured currently).

very cool, would be interested to see this approach applied to other markets

It took quite a while for the overlay to appear. Be patient if you want to see the data.

There's a lot more than these 6 brands. You have New Days, Daily Yamazaki, and the competition of mini markets as well such as My basket...

this is very cool! I love how responsive the interface is.

There was no war until a map was presented lol

Sorry but this seems like vibe coded slop

You cant search or change language

Idk what is the goal here, but maybe some analysis with graph would be better, like who has the most territory or something like that? You also might need to disclosure how you got this data
