Literally translated as “south of Sendai,” the Sennan Area is located in the southern region of the prefecture. It is comprised of the following municipalities: Kawasaki, Murata, Shibata, Kakuda, Ogawara, Zao, Marumori, Shiroishi, Shichikashuku.

Home of our lovely Mount Zao, Sennan is a wonderful place to see all year long. Being so close to Fukushima Prefecture, much of the food cuisine jumps the border in Sennan.  

Shiroishi is also the home of the ONLY standing Japanese castle in the prefecture. Ogawara has the prefecture's most famous cherry blossom sightseeing spot.  And Kakuda has the JAXA Space Center that has a FREAKING (model) ROCKET standing out front. 
Where to Eat
There are many restaurants along Route 4. You'll be sure to find something you like.

Blu Sta in Ogawara is a nice and date friendly place to dine. It can get very crowded and they do not take reservations so plan ahead.
Chain restaurants are a good deal. Mos Burger (has a vegetarian option which is delicious), Milky Way, Gusto, CoCo's, Joyful... but be aware that most Japanese made foreign food (Japanese Italian or Indian...) is not exactly the same as you might expect.Cheap restaurants such as ramen shops, McDonalds, and Kapa (cheap sushi) are plentiful.

Pizza can be found in Kawasaki on 457 heading toward Mt. Zao, and in Zao at a small brick oven pizza place.

Shoya ramen shop in Kakuda. The best miso ramen in Japan!

Tasuke Sushi on the Route 4 heading towards, but just outside Shiroishi.

Umen (Shiroishi's noodle)restaurants of which there are quite a few in walking distance from Shiroishi station.

Yoshinoya and Sukiya – affordable Japanese style food with healthy choices

Where to Shop
100 (hyaku) yen shops are the best. Also called Diaso these shops litter the countryside and the cities with a variety of goods for teaching and living. Check out the excellent stationary.

Aeon or Food Max grocery stores also have the same items you would find at 100 yen shops. They also have some pretty good deals on food.

COOP is a large grocery store found throughout Miyagi prefecture. There is one located in Ogawara and Shiroishi.

D2, DIY and Komeri are good houseware stores in Murata, Shiroishi and Ogawara.

Diamond City is a mall in Natori. Although not in the Sennan area, Natori is pretty close to many Sennan area JETS and there is a JR Line stop which drops you off at Diamond City. Diamond city, larger then Forte offers more variety of stores, two large grocery stores in the mall, has foreign foods, and a movie theater.

Forte Mall in Ogawara might be small, but has a variety of stores for grocery or clothing. It also has a movie theater.

Yoku Benni Mart is a grocery store with some selection of foreign food items.

Local Shops: There are also any number of local establishments in small towns which offer fruits and vegetables and other items. A lot of these places are even first floors of homes. Give them a try. There are also outdoor farmers markets scattered throughout the Sennan area. Ask about these at your Board of Education or Community Center. Farmer's markets tend to offer better deals on produce.

Mt. Zao is home to great skiing on both the Miyagi and Yamagata sides of the Zao range. There is also Okama (the crater lake) accessible through the Miyagi side and winter "snow monsters" which are best seen on the Yamagata side of things.

Onsen- (another plug for onsen, see entertainment). Shiroishi has lots of good onsen. There are two main areas near Shiroishi  (Obara and Kamasaki). At Obara Izumiya is a good hotel. At Kamasaki, it's Suzukiya. At both you can get an onsen for 500 yen and they have good rotenburo (outdoor baths).

Shiroishi Castle and Samurai House are both within walking distance from the train station.
