While scent is often called the third sense in humans, its significance has not been highly valued. Considering our daily lives, we live buried in a flood of visual and auditory information, and we have rarely shown much interest in fragrance.

Recently, however, it has been pointed out that scents act on brain function and have a significant impact on cognition and emotion. Research is also being conducted to clarify such effects through the latest brain functional imaging and EEG analysis. Unfortunately, however, results for Japanese herbs are currently scarce, with the exception of a few such as Yuzu and Kuromoji.

Shiso is a modest-looking herb that can be grown in gardens or on balconies, and its usual role is as a garnish for main ingredients. For some time, I have held expectations that the scent of shiso activates brain function and, to put it a bit grandly, might even be useful in preventing dementia. I hope to provide physiological evidence that it improves cognitive function and help shiso transition from a supporting role to a leading one.

If I told you that every household in Naruko has been making "shiso-maki" (shiso rolls) since long ago, you would surely be surprised. However, that was the case until around the beginning of the Showa era. Today, only three or four shops remain that make them while preserving that tradition. In today's busy world, they can be bought at shops more deliciously and cheaply than making them at home. Speaking of Naruko's "shiso-maki," they were very popular among hot-spring guests as souvenirs of Naruko Onsen, which is famous for kokeshi dolls. Over time, they gained a reputation as a local product of Tohoku, and today they are handled as popular items at regional product fairs nationwide.

Let me introduce a simple recipe. Mix sesame seeds, walnuts, miso, and a little sugar, knead well, and wrap the mixture in green shiso leaves. Add chili pepper if you like, skewer three pieces, and fry them quickly in oil. When freshly fried, they are crispy, and the scent of shiso and the sweet-and-salty taste of miso fill your mouth. As an accompaniment to a meal or sake, these are excellent items that leave you needing nothing else.

I hope you will all try them at least once.

Plums in Odawara City are cultivated mainly in the Soga Plum Grove, which is counted among the three major plum groves in the Kanto region, and boast the largest production volume in Kanagawa Prefecture. The Soga district is blessed with a warm climate and nature, with the Sakawa River nearby providing good water quality and the sea close by. Historically, plum cultivation has been carried out since before the rule of the Hojo clan, the warlords of the Sengoku period, and in the Edo period, pickled plums appeared as a famous product of Odawara in the comic novel "Tokaidochu Hizakurige." Among them, the Juro Umeboshi is an original Odawara variety whose name is derived from the Soga brothers, Goro and Juro, the protagonists of "The Tale of the Soga," which was also adapted into Kabuki plays. The harvest season is from mid to late June.

Compared to general varieties, Juro Umeboshi are considered the finest variety for pickled plums because the flesh is thick and soft and the seeds are small. Because the skin is thin and easily torn during the harvest season, they are carefully picked by hand one by one. There are red umeboshi, which use red shiso for coloring and flavoring, and white umeboshi, which are pickled only with salt and plums. Juro Umeboshi are traditional white umeboshi that have soaked up plenty of the sun's blessings during the midsummer drying process (Doyoboshi). Why not take this opportunity to compare the different types?

Shiranuka, a nature-rich town overlooking the Pacific Ocean in eastern Hokkaido, is my hometown. I grew up spending time with nature, going to pick Siberian onion, ostrich ferns, and bracken in the spring, or going to the sea with my father to fish for pond smelt (sometimes a red fox would run off with the fish we caught...). Blessed with rich fishing grounds, it became known nationwide for seafood such as shishamo smelt, salmon, and whelk, and in recent years, for cheese production. A particularly prominent presence in Shiranuka is the shiso shochu "Tantakatan." It was born when shiso growers began mixing shochu with juice made from shiso, and was later manufactured and sold as part of a town revitalization project. I hear it initially spread nationwide through word-of-mouth from "succhi" (meaning female cabin attendants). Shiso-based products are not limited to shochu but extend to ramune soda and soy sauce. Just before the harvest in September, the shiso fields are dyed entirely purple... Why not pay a visit? By the way, "Tantaka" means flounder in the Ainu language.
