AEON TOWN Sanuma

AEON TOWN Sanuma (イオンタウン佐沼) is a shopping center located in Tome City, Miyagi Prefecture, Japan, operated by AEON TOWN Co., Ltd., a subsidiary of the AEON Group. The facility opened in October 2007 as Rock City Sanuma (ロックシティ佐沼), developed and managed at the time by Rock Development Co., Ltd. It was renamed AEON TOWN Sanuma in September 2011 after AEON Co., Ltd. acquired all shares of Rock Development and rebranded the company as AEON TOWN. The center is anchored by an AEON Super Center Sanuma store and includes a mix of specialty tenants such as Yamada Denki and Daiso, with roughly 37 specialty shops alongside the core store. At opening, the tenant mix comprised 47 tenants in total, including food and beverage, fashion, and general merchandise operators. The shopping center serves the Tome area of northern Miyagi Prefecture and is accessible by car and local bus. As part of the AEON Group, AEON TOWN Sanuma participates in group-wide retail programs and services, including the AEON app, WAON POINT loyalty program, and periodic promotional events. The facility has undergone operational changes over the years, including the transfer of the AEON Super Center Sanuma store's operations to AEON Tohoku Co., Ltd. in 2025 following a merger. The center remains an active regional shopping destination in Miyagi Prefecture.

AEON TOWN Sanuma opened on October 25, 2007, as a soft opening, followed by a grand opening on October 27, 2007, under the name Rock City Sanuma (ロックシティ佐沼). It was developed and operated by Rock Development Co., Ltd. At the time of opening, the center housed 47 tenants, including an AEON Super Center and Yamada Denki as leading tenants, along with 11 food and beverage tenants, 13 fashion tenants, and 10 general merchandise tenants. Some tenants, such as the AEON Super Center and Plaza Capcom, operated longer hours than typical tenants. On August 31, 2011, AEON Co., Ltd. acquired all shares of Rock Development Co., Ltd., making it a wholly owned subsidiary, and on September 1, 2011, the company was renamed AEON TOWN Co., Ltd. As part of this change, facilities were progressively renamed from Rock Town to AEON TOWN, and this location was renamed from Rock City Sanuma to AEON TOWN Sanuma. In 2020, operational changes occurred: on March 1, the liquor section of the AEON Super Center Sanuma store was transferred from AEON Retail to AEON Tohoku following the establishment of AEON Tohoku Co., Ltd. On April 1, free plastic bag distribution ended at AEON directly operated sales floors nationwide, including this store. On March 16, 2022, the Fukushima offshore earthquake caused damage to the center, including collapsed ceilings and walls. On March 1, 2025, following a merger, the entire sales floor operation of the AEON Super Center Sanuma store was transferred from AEON Super Center to AEON Tohoku Co., Ltd. The center continues to operate as a regional shopping destination in Tome City, Miyagi Prefecture, with the AEON Super Center Sanuma store as its core, alongside approximately 37 specialty stores including Yamada Denki and Daiso.
