紅まどんな – Beni Madonna

by

Beni Madonna is a premium citrus fruit from Ehime Prefecture, known for its incredibly soft pulp that feels just like eating jelly. It took 15 years of careful breeding to combine the best traits of its parent varieties: the juicy Nanko and the tender Amakusa.

Every year, farmers cross-breed about 1,000 different varieties in search of something new, but they consider themselves lucky if they can produce just one successful variety every 15 to 17 years. The odds are a staggering 1 in 15,000. Even with its premium price tag, Beni Madonna is selling like hotcakes. Peak season is in December, and it’s expected to be available through early January.

愛媛県が生んだ最高級の柑橘「紅まどんな」。果肉が非常に柔らかく、まるでゼリーを食べているような食感が特徴。これは15年もの歳月をかけ、ジューシーな「南香（なんこう）」と、果肉が柔らかい「天草（あまくさ）」の長所を掛け合わせて作られた品種。

農家では毎年1,000種類ほど掛け合わせて新種の開発を行っているが、新しい品種が誕生するのは15年〜17年に一度あれば良い方だと言われている。その確率はなんと約15,000分の1。現在、紅まどんなは決して安くないけれど、その美味しさから「飛ぶように」売れている。12月が旬のピークで、1月初めまで販売される予定。

納豆 – Nattō

by

Nattō is made by fermenting soybeans with nattō bacteria. It has a distinct smell and a sticky texture, which even many Japanese people find unappealing despite growing up with it. However, nattō is a nutritional powerhouse—rich in protein, essential for the body; iron, which supports blood production; and potassium, which helps regulate blood pressure. It also promotes a healthy gut environment. When it comes to nutritious foods, nattō is often the first thing that comes to mind for many Japanese people.

Interestingly, the bacteria responsible for nattō’s fermentation have remarkable resilience and an astonishing ability to reproduce. Experiments have shown that nattō bacteria can survive extreme conditions—temperatures as high as 100°C, as low as -200°C, the vacuum of outer space, and even the acidity of gastric juices. Incredibly, a single nattō bacterium can multiply to about 4 billion within just 16 hours.

納豆は大豆を納豆菌で発酵させて作られる。納豆は癖のある匂いと独特の粘りがある食べ物で、納豆文化の中で生活している日本人でも嫌いな人は多い。しかし納豆は体に大切なタンパク質、血を作る鉄分、高血圧防止に効くカリウムが豊富で、腸内環境も整えてくれるという超優れ物で、健康食品の代名詞として日本人が一番最初に挙げるのは納豆だ。

ところでこの納豆を作っている納豆菌なんだが、驚異的な生命力と物凄い繁殖力を持っている。実験の結果、納豆菌は100度の高温やマイナス200度の低温、宇宙空間、胃液の中でも生き延びることができ、1個の納豆菌は16時間後には約40億個まで増殖可能ということが分かっている。

Neo Hina Dolls

by

March 3rd is Hinamatsuri, a festival for families with girls. However, in recent years, many younger people have lost interest. During Japan’s economic boom, a seven-tiered Hina doll display cost around 1 million yen, nearly the price of two new cars, symbolizing wealth. Nowadays, space and cost concerns lead families to buy only the main couple dolls or even just small figures or pictures. To attract younger generations, flashy Hina dolls with long eyelashes, bright hair, and vibrant kimonos have emerged. While some find them too flashy, these changes aim to keep the tradition alive.

3月3日はひな祭り。女の子がいる家庭は既に何かしら準備していることだろう。でも実は近年、若い世代の節句離れが起きている。高度経済成長期の7段飾りのひな人形は100万円。新車2台がほぼ買える値段。豪華なひな人形が豊かさの象徴だった。でも今は「家が狭くて置く場所がない」「高い」などの理由で、買っても男雛と女雛の2体だけ、それどころか従来の人形の代わりに手のひらサイズの飾りや絵などで済ませる家庭も多い。そこで少しでも若い世代に興味を持ってもらおうと、最近ド派手なひな人形が売られている。長いまつげ、鮮やかな色の髪の毛、派手な着物など、とにかく従来のひな人形とは全然違う。ド派手は少しやりすぎな気がしないでもないが、伝統を守るには変わっていかないといけないのだろう。

白神山地 – Shirakami Sanchi

by

Japan currently hosts 26 World Heritage Sites, including Shirakami-Sanchi, a mountainous region spanning Aomori and Akita Prefectures. Recognized in 1993, Shirakami-Sanchi boasts vast primeval beech forests, among the largest untouched natural reserves globally. These ancient forests, free from modern development, provide sanctuary to a rich diversity of flora and fauna, including the elusive black woodpecker and the Japanese serow, a designated natural monument.

白神山地は現在日本にある26の世界遺産の一つ。白神山地は青森県から秋田県にまたがる山地帯の総称。「人の影響をほとんど受けていない原生的なブナ天然林が世界最大級の規模で分布」として、1993年世界遺産に登録された。白神山地は幻の鳥と言われるクマゲラや天然記念物のニホンカモシカなどの保護区になっている。

National Foundation Day

by

February 11th is National Foundation Day (建国記念の日) in Japan. Established by the amendment of the National Holidays Act in 1966, this national holiday is dedicated to “remembering the founding of the country and cultivating a love for the nation.” February 11th was chosen for this celebration because it is traditionally believed to be the day when Japan’s first emperor, Emperor Jimmu, ascended the throne in 660 B.C., according to Japanese historical records.

建国記念の日は、1966年の祝日法改正により設けられた国民の祝日であり、「建国をしのび、国を愛する心を養う」日とされているんだそう。2月11日が選ばれた理由は、紀元前660年、日本の初代天皇である神武天皇が即位したとされる日だから。

Neo Bamboo Craft

by

In Beppu, located in Oita Prefecture, traditional bamboo craftsmen and modern artisans collaborate to create innovative, non-traditional works. This collaboration is possible because Beppu hosts Japan’s only vocational training school for bamboo crafts, where tuition is free! Inexperienced craftsmen attend this school to learn how to handle and weave bamboo, develop product creation ideas, and gain opportunities to produce innovative products.

大分県別府では伝統的な竹細工職人と現代の職人がコラボして自由で斬新な作品を作りだしている。別府には日本で唯一竹細工の職業訓練校がある。しかも授業料は無料！経験の浅い職人などが通って、竹の扱い方や編み方を習ったり、商品開発の考案から実際の作成を行ったりする。

Gold Ehōmaki

by

The price of an ehōmaki made with gold seaweed is 12,800 yen. With the current strong dollar, this converts to approximately 83 dollars, lessening its impact. However, when the exchange rate was 100 yen to the dollar, 12,800 yen would have been 128 dollars. The one with sea urchin on it was from 2019 and cost 15,800 yen, which was around 145 dollars at the then-current exchange rate. Despite the rising costs, I wonder why the price of this particular ehōmaki has decreased…

Trivia about Setsubun

by

 

Setsubun (節分), usually celebrated on February 3rd, marks the day before the first day of spring according to the East Asian lunisolar calendar. However, due to the Earth’s orbital period of 365.2422 days, the date of Setsubun can shift. For instance, in 2021, as well as this year, Setsubun falls on February 2nd, a date that hadn’t occurred since 1984.

On Setsubun, it’s customary to perform mamemaki and enjoy ehōmaki. However, this year, the price of ehōmaki has surged by nearly 15% compared to last year. This increase is largely due to the price of rice, which has skyrocketed by 60% over the same period.

今年の節分は2月2日。節分は2月3日のことが多いが、そもそも節分とは立春の前日のこと。地球の公転の周期は365.2422日なので立春の日付けがずれる。2021年も2月2日が節分だった。その前は1984年まで遡る。

節分には豆まきをしたり恵方巻きを食べたりするのが習慣だが、今年の恵方巻きは去年と比べて15％近く値上がりしているそう。特にお米の値段が去年より6割も高くなっているそうだ。
