OSAKA--Kayoko Maki’s blood boiled when she browsed the city-themed coloring book section at a 100-yen shop here last summer.

“Nandeyanen?” (What the heck?), she said to herself in the Osaka dialect.

New York, Paris, Tokyo and Kyoto were all represented in the coloring books. But her beloved hometown of Osaka could not be found on the shelf.

Maki had a reason to be upset by Osaka’s exclusion. It was only two years ago when The New York Times listed Osaka on its annual “52 Places to Go” list, along with the mouth-watering accolade: “If Kyoto represents Japan’s spirit, and Tokyo its heart, Osaka is the country’s insatiable appetite.”

The city also received an estimated 10 million foreign visitors in 2017, according to the Osaka Convention and Tourism Bureau.

A disappointed Maki became determined to have Osaka represented.

Maki, 42, was born and raised in Osaka’s busy commercial district of Nanba, which is also known as Minami. She is now president of Link Corp., a company that provides support and services to local businesses seeking to attract foreign visitors.

With help from illustrators, Maki created the foldable Osaka Namba Coloring Map (Namba Nurie).

Measuring 30 by 40 centimeters, the line-art map shows local symbols and landmarks from the Dotonbori river in the north to Nankai Nanba Station in the south. People can add color to the map on their own.

Nanba’s iconic features, such as the giant crab on Kani Doraku restaurant’s billboard and the Kuidaore Taro clown, are crammed into the illustration side by side with Kuromon Ichiba market and other popular sightseeing places.

Maki intended to make a map easy to comprehend. She is confident that it conveys an image of Nanba as “an attractive place with full of energy” to everybody, “from children to those who don’t speak Japanese.”

Place names also appear in hiragana and English.

The map reflects Osaka’s playful spirit.

On closer look, street trees depicted on the map are, in fact, “kushikatsu,” or deep-fried meat on a skewer, an Osaka specialty.

A little boy holds a bunch of balloons on the map. But a second look confirms that they are “takoyaki,” a ball-shaped snack filled with diced octopus, another local specialty.

In front of Nanba Grand Kagetsu theater on the map, a duo of standup comedians appears. Everybody walking on the street in the map is smiling.

Maki hopes the coloring map will make children beg their mothers, “Let’s go to Nanba one more time.”

She has been selling the map to hotels and restaurants in and around Nanba as a novelty item. It is also available for 100 yen ($0.91) at Link Corp.
