> I noticed that my neighborhood is all Lawsons

There's a Lawson-heavy area about a twenty-minute walk from where I live in Yokohama. The three convenience stores closest to me, though, are 7-11. One reason for this clustering, I suspect, is deliveries. Convenience stores are carefully designed for logistical efficiency, and having stores close to each other must shave a bit off the distance traveled by delivery trucks.

You might consider adding Aeon My Basket stores to your map, too. They have sprouted up all over the Tokyo region in recent years. They are positioned as small supermarkets rather than kombini, but their size, locations, and product overlap with kombini puts them in competition with Lawson, 7-11, etc., too.

This brings back memories of life in Kawasaki. I used to live in Kawasaki nearly 15 years ago for eight months, and I still visit regularly, twice a year in fact since the pandemic ended. I was an intern at Fujitsu and lived in a company dorm. Within a two-minute walk from my dormitory was a My Basket, where I did much of my shopping. It didn’t have the largest selection of food, but it carried the essentials and was very close. It was closer to me than the nearest konbini, a Seven Eleven that was three minutes away :).

Seven minutes away was a larger grocery store called Maruetsu, and ten minutes away from my dorm room was Musashi-Nakahara Station, which had a grocery store (I forgot the name) about the same size as Maruetsu. What I loved about these latter two grocery stores was the nice selection of hot foods, especially around lunch time when many workers from Fujitsu and other nearby companies went to buy hot bento. I still remember the ¥300 bento from the grocery store inside the train station. It was tasty and was reasonably filling.
