Isumi City (いすみ市; -shi) is located on the east coast of southern Chiba Prefecture on the Boso Peninsula. It is next to the Pacific Ocean and can experience humid summers but mild winters. There are approximately 41,014 people living in Isumi City as of March 1st, 2010. Isumi City was formed when the towns of Misaki, Ohara, and Kuniyoshi combined; including neighboring Otaki, Onjuku, and Katsuura, the area is known as 夷隅郡市 (Isumi gunshi). Note: Many of the older generations will refer to Kuniyoshi as Isumi-machi or Isumi. Kuniyoshi was the original Isumi before the merger. The old Isumi is written with kanji while Isumi City is written in hiragana.

Take a drive along Route 128 and there are plenty of ramen shops to fulfill even the most ramen hungry stomachs.

Teishoku (set meals)

On Route 128 right next to Beisia in Ohara. Conveniently located and conveniently priced.

This family owned restaurant is one of the best eat-outs in the area. An ALT favorite for the past few years. The teishoku portions are enormous and are very decently priced. Definitely try the ninnikku teishoku or the shouganikku teishoku. The garlic flavored meat dish or the ginger flavored meat dish served on a bed of cabbage with white rice, miso soup, and a seasonal side dish are to die for.

Located in Kuniyoshi. Right across from the Superland grocery store.

Local Tips and Tricks/Misc.

  • Try not to miss the train, they only come once every hour in either directions. Only during the morning rush will there be multiple trains in the same hour.
  • Last trains going North end at 9 PM, but last trains going South end as late as 12:30 AM. Plan accordingly or you'll find yourself stranded or with a very expensive taxi ride.
