The Inaho (いなほ) is a limited express train service in Japan operated by East Japan Railway Company (JR East), which runs from Niigata to Sakata and Akita. The train runs along the Uetsu Main Line with views on the coast and Dewa Range.

Three return workings daily operate between Niigata and Akita, with a further four return workings between Niigata and Sakata.

Inaho services stop at the following stations:

Niigata - Toyosaka - Shibata - Nakajō - Sakamachi - Murakami - Fuya - Atsumi Onsen - Tsuruoka - Amarume - Sakata - Yuza - Kisakata - Nikaho - Ugo-Honjō - Akita.

Since 12 July 2014, all regular Inaho services are operated by seven-car E653-1000 series EMUs displaced from Fresh Hitachi services on the Joban Line. The first set was phased in on Inaho services from the start of the revised timetable on 28 September 2013. The E653 series trains are modified with the addition of a Green (first class) car and a new livery evoking images of the sunset, rice plants, and the sea.

Inaho services were previously operated by six-car 485 or refurbished 485-3000 series electric multiple unit (EMU) trains based at Niigata Depot, but these trains were replaced by E653-1000 series sets from 12 July 2014.

Services are operated by 7-car E653-1000 series sets, formed as follows, with car 1 at the Akita end and car 7 at the Niigata end. All cars are no smoking.

Seating in the E653 series Green cars is arranged 2+1, with 18 seats in total.
