• Joetsu Line: Ino (Gunma) ⇄ Takasaki

Takasakitonyamachi Station opened on 16 October 2004 as an infill station on the Jōetsu Line, 2.8 km from Takasaki. The station name derives from the adjacent Takasaki Wholesale Retailer Industrial Estate ("tonyamachi"), and the building is elevated above the platforms at right angles, with two named entrances — Tonya on the west and Kaizawa on the east. JR East operates a Midori no Madoguchi reserved-ticket office on the concourse. The station serves Jōetsu Line trains and through-running services that branch onto the Agatsuma Line toward Ōmae and the Ryōmō Line toward Oyama.

The station is named after the large tonyamachi — an industrial estate for wholesale retailers — that stands next to it. Its immediate neighbours also include Gunma Paz College and three Gunma prefectural high schools: Takasaki Girls', Takasaki Technical and Takasaki Commercial.
