Koshigaya Laketown: One of Japan's Largest Shopping Malls

Vast stores continuing as far as the eye can see, a lakeside promenade, and so many shops you cannot get around them in a single day: Koshigaya Laketown in Koshigaya City, Saitama Prefecture, is a giant shopping complex boasting one of the largest scales in the country. Of course shopping, but also gourmet, movies, and a lakeside stroll offer a fullness you can enjoy for a whole day. Let's head to this popular spot, perfect for a family outing, where shopping and leisure fuse.

One of Japan's Largest Shopping Facilities

Koshigaya Laketown is a giant complex commercial facility in Koshigaya City, Saitama Prefecture. Its core, "Aeon Laketown," is known as a shopping mall boasting one of the largest total site areas and total floor areas in the country. It consists of three areas: "kaze," "mori," and the outlet, and its scale is overwhelming. Because it is so vast, it boasts a number of shops you cannot get around in a single day. From fashion to general goods to home appliances, every kind of shopping is completed in one place, truly a hall of shopping.

Diverse Shops and Gourmet

The charm of Koshigaya Laketown is, above all, the sheer number and variety of its shops. From popular fashion brands to lifestyle goods, bookstores, and electronics retailers, specialty shops of every genre stand in a row. At the adjacent outlet, there is also the pleasure of buying brand items at a good price. Furthermore, the food court and restaurants are plentiful, and you can savor various gourmet cuisines, whether Japanese, Western, or Chinese. There are also a movie theater and amusement facilities, and a major charm is that you can play all day, not just shop.

Lakeside Leisure

True to the name "Laketown," this facility is located on the lakeside of the regulating reservoir "Osagami Regulating Pond." Along the shore of this pond, also fondly known by the nickname "Sakura Lake," a lakeside promenade and parks are maintained, and you can enjoy a walk while gazing at the lake between shopping. The open environment where you can get close to water and greenery is a charm a notch different from urban-type shopping malls, making it a unique spot where you can enjoy shopping and an outdoor stroll at once.

Access and Basic Information

Since indoor facilities are the center, you can enjoy it comfortably year-round. The lakeside stroll is recommended in the mild climate of spring or autumn. Access is excellent: directly connected from "Koshigaya Laketown Station" on the JR Musashino Line to the kaze building via Laketown Gate. Access from the city center is also good, and a charm is that it is easy to visit by both train and car. Since business hours differ by shop, it is reassuring to check your target shops in advance.

Practical Travel Notes

Because each of the three areas is vast, it is efficient to decide your purpose before going around. For fashion and general goods, head to kaze and mori; for bargain brand shopping, go to the outlet. Getting a floor map and knowing the locations of the food court and restaurants makes breaks and meals smooth. Weekends, holidays, and long vacations are especially crowded, so visiting just after opening or on weekdays is comparatively relaxed. Since there is a lot of walking, comfortable shoes are recommended.

A Word of Advice

The scale is so large that it is difficult to see everything in one day, so narrowing down the shops or areas you want to visit in advance raises your satisfaction. Between shopping, taking a stroll along the waterside of the Osagami Regulating Pond to catch your breath is recommended. The open lake scenery is perfect for a change of pace from indoor shopping.
