Tanabata & Sōmen
Tanabata (Star Festival) on July 7 is a festival in Japan that centers on the tale of 2 stars Orihime (Vega) and Hikoboshi (Altair). These 2 lovers were separated across the Milky Way “river” and can only meet once a year if there is fair weather. If rain falls on July 7th, it is poetically called 洒涙雨 (sairiyū, “a rain of tears”) as the 2 lovers cannot cross the Milky Way and their reunion is postponed for another year. The food traditionally eaten on this day in Japan is sōmen, chilled wheat noodles. Sōmen can be traced back to China’s sùmiàn/suomen, which when deep-fried were called saku-bei/sakumen and given as an offering on the seventh day of the seventh month to ward off illness. Over time, this dish evolved into the fine wheat noodles eaten today and became established as the traditional dish eaten on Tanabata for good health.
Why sōmen on Tanabata? The white, silky noodles are likened both to the Milky Way and the threads of Orihime’s weaving in the traditional Tanabata tale. People sometimes eat sōmen as a prayer for skill in the crafts and arts, as Orihime is said to be an exceptionally skilled weaver. Sōmen noodles are also easy to digest in the hot summer weather. Beginning in the Heian period and increasing in popularity in the Edo period, sōmen became the customary gift to give on Tanabata and July 7th is now recognized as “Sōmen Day” in Japan.
This recipe is a tomato “bukkake” sōmen: fresh tomatoes, tuna, sesame oil, and ground sesame make it refreshing yet full of umami. Celebrate Tanabata’s wish for health with this simple bowl.

Feel free to increase the amount of mentsuyu or ground sesame seeds to taste.
For 2 servings, use roughly half the amount.
Be sure to drizzle sesame oil over the noodles themselves so the strands are nicely coated.
