The four seasons in Japan are clearly defined.  In the Kanto region where Oarai is located, each season lasts around three months.

In Oarai, 'Kanbai' or plum blossom season begins at the end of February, with the plum trees reaching full bloom at the end of March. Picnicking under the blossom is a popular Springtime activity.

Throughout April and May the temperature rises gradually and the year's rice is planted, bringing greenery to Oarai and the surrounding countryside.  After the rainy season in June,  Summer begins.

Summer in Oarai is generally hot and humid,  with temperatures often surpassing 30 degrees. Late Summer also brings with it the typhoon season, which lasts until early October.  Swimming in the Pacific and attending festivals and firework shows in the evening are popular summer activities.

Towards the end of September, the Summer heat begins to fade and the first signs of Autumn appear, including beautiful Autumn foliage and the bright harvest moon 'Chushu no Meigetsu' in October and November, During Autumn, the year's rice crop is harvested.
December in Oarai is very cold but the weather is generally crisp and clear.  The average winter temperature is around four degrees.  In mid-February the first welcome signs of Spring reappear along with the plum blossoms.

Rainbow City Friendship Agreement with Nyköping, Sweden

Following mutual visits from delegations headed by the mayors of Nyköping and Oarai, a warm and cordial relationship has been established between the two municipalities, confirmed by the signing of a Rainbow City Friendship agreement on May 23, 2006 in Oarai. This is the first such agreement signed by Oarai, nationally or internationally.

Nyköping and Oarai share much in common. Both are coastal towns with a rich history, located within 100 km of their respective national capitals. Oarai looks forward to a deepening of mutual ties and exchanges between local residents, civic groups and business.

Many species of fish can be found in the sea around Oarai including sardines, flatfish and various kinds of clam and shellfish.  These fish are usually eaten either raw or deep fried.  Many restaurants in Oarai use locally caught fish in their sushi, sashimi and other seafood dishes.  These are also many fish processing plants in Oarai which produce other seafood products for distribution around Japan and internationally.

In recent years the catch of these fish has declined and there has been a move towards a more sustainable fishing policy in the area.
Oarai's main agricultural products are rice,  sweet potato,  daikon (Japanese radish) and other vegetables.  In 2005, some of the sweet potato crop was distilled to make 'shochu', a Japanese liquor.  This drink has proved to be very succesful.

From 2006,  rice produced in Oarai has been used in school lunches.  One day each month,  the school lunch is made using produce from local farms and fisheries,  The project is being used to educate children on the importance of buying local produce.
