静岡にある老舗茶屋の娘・伊井田鈴は、ある日、遊びに行っていた東京でお婆さんが足を挫く怪我を負った現場に居合わせる。鈴はお婆さんの手当てを行い、そのお礼として鈴はお婆さんからお茶を貰う。そのお茶が今まで飲んだこともないような素晴らしい味だったため、情報を得たいと考えた鈴は情報を集める最中に、たまたま買った宝くじで大金を当てた。この大金は「お婆さんのお茶から貰ったお金」と考えた鈴は大型車を購入、車を改造して移動茶店「茶柱倶楽部」を開き、お茶をくれたお婆さんの手がかりを探すために日本全国を回る旅に出る。
お婆さんを探す旅に出てから1年が経とうとしていたある日。福岡県博多で「茶柱倶楽部」を営業していた、鈴は前夜の夕食に訪れた小料理店の店主からお婆さんに関する情報を得た。お婆さんの名前は、「佐山高子」。彼女は、佐賀県の嬉野市在住で、家では代々緑茶を製造している。高子の元へ向かう前夜、高子の茶畑がある山を散策した鈴は茶の大樹の下に体調を崩して倒れていた高子を発見する。携帯で店主に連絡を取り、慌てて高子を連れ帰り、医師を呼んで、高子はようやく快方へ向かう。あの「香りの金冠を戴く霊峰のようなお茶」を高子に煎れた鈴は、このお茶を伝えていくようにと高子に頼まれる。
高子との出会いを経て、しばらくの後。鈴の元へ神奈川県横浜市出身の大学教授・「桜井夕貴」が訪れ、彼はお茶の研究をしており、高子の紹介で彼女の存在を知り、鈴に自身の日本茶研究を手伝って欲しいと言うのだ。鈴は10月のシルバーウイークに地元・川根市で開催したイベントがきっかけとなり、再び茶柱トラックで全国を回ることに。北は北海道から南は沖縄、さらには台湾と様々な土地を回る日々を経て、鈴は「日本全国『茶柱倶楽部』化計画」を思い立つ。ある日鈴は、香川県を訪れた際に四国八十八箇所お遍路旅をしている、資産家の孫娘・「大室里乃」と知り合う。彼女に祖父母へのお土産にと選んだ「歩危番茶」がきっかけとなり、岡山県吉備津神社で出会った、里乃の祖父のある言葉に自問自答した鈴。ついに彼女は、来年の秋に「お茶祭り」を開催することを決断。
埼玉県川越市で、鈴は里乃の祖母と初対面。そこで鈴は「幻の玉露」をいただき、感激するがその玉露を送ってくれたのは、彼女の長年の親友であることが判明。しかし、その親友は不慮の事故で頭部を負傷。自身のことや玉露のことも忘れてしまっていたのだ。それを知った鈴は「幻の玉露」探しに乗り出すことを決意。旅の途次、鈴はかつて茶柱トラックを出店した滋賀県大津市の和菓子店で、ついに「幻の玉露」を見つけた。大室邸で開かれた茶会で、鈴は玉露を淹れ、玉露が見つかった経緯を話す。そこへ、大室夫人の親友・「さゆり」が現れた。彼女も茶会に加わり、玉露を飲むも記憶が戻ることは無かったが、2人は変わらぬ友情を誓い合う。
1年後。横浜市をメイン会場に『旬茶祭り』を開催。最初に日本茶を海外へ輸出した幕末の女性実業家・大浦慶の地元・長崎県も会場となり、かつて鈴が茶柱トラックを出店した各都道府県の関係者も来場。高子や里乃・鈴の従姉妹・森田望も手伝いに駆けつけ、桜井の著書も会場で発売されるなど一大イベントとなった。イベントは大成功に終わり、感涙する鈴。
そして今日も鈴は、多くの人たちに茶を煎れている。〔完〕
One day, Iida Suzu, the daughter of a long-established tea shop in Shizuoka, is visiting Tokyo when she happens to see an old woman sprain her ankle. She treats the old woman, and in return she receives tea from the old woman. The tea tasted so amazing that she had never tasted it before, and while she was gathering information she wanted to get more information. She happened to win a large sum of money on a lottery ticket while gathering information. Thinking that this large sum of money was “money from the old woman’s tea,” Suzu buys a large truck, modifies it, and opens a mobile tea shop called “Chabashira Club,” and sets off on a journey around Japan to find clues about the old woman who gave her the tea.
One day, almost a year after she set out on her journey to find the old woman, Suzu, who was running the “Chabashira Club” in Hakata, Fukuoka Prefecture, gets information about the old woman from the owner of a small restaurant she visited for dinner the night before. The old woman’s name is “Sayama Takako.” She lives in Ureshino City, Saga Prefecture, and her family has been making green tea for generations. The night before she went to visit Takako, Suzu went for a walk in the mountains where Takako’s tea fields are located and found her lying ill under a large tea tree. She contacted the owner on her cell phone, hurriedly brought Takako home, called a doctor, and Takako finally recovered. Suzu brewed the “tea like a sacred mountain crowned with a golden crown of fragrance” for Takako, and Takako asked her to pass on this tea to others.
Some time after meeting Takako, Suzu was visited by “Yuki Sakurai”, a university professor from Yokohama City, Kanagawa Prefecture. He was researching tea and learned of her through Takako’s introduction, and asked Suzu to help him with his research on Japanese tea. After an event held in her hometown Kawane City during Silver Week in October, Suzu once again traveled around the country in her tea stick truck. After traveling to various places from Hokkaido in the north to Okinawa in the south and even Taiwan, Suzu comes up with the idea of ”creating a tea leaf club all over Japan”. One day, when Suzu visits Kagawa Prefecture, she meets “Omuro Satono”, the granddaughter of a wealthy man who is on a pilgrimage to the 88 temples of Shikoku. Suzu chooses “Boke Bancha” tea as a souvenir for her grandparents, which leads her to question herself about a certain word that Satono’s grandfather said at Kibitsu Shrine in Okayama Prefecture. Finally, she decides to hold a “tea festival” next autumn.
In Kawagoe City, Saitama Prefecture, Suzu meets Satono’s grandmother for the first time. There, Suzu is thrilled to receive “the legendary Gyokuro”, but it turns out that the person who sent it to her was her long-time best friend. However, that best friend suffered a head injury in an accident. He had forgotten about himself and Gyokuro. Upon learning this, Suzu decides to go on a search for the “legendary Gyokuro”. During her travels, Suzu finally finds the legendary gyokuro tea at a Japanese sweets shop in Otsu City, Shiga Prefecture, where the tea stalk truck used to be. At a tea ceremony held at the Omuro residence, Suzu brews gyokuro tea and talks about how she found it. Then, Mrs. Omuro’s best friend, Sayuri, appears. She also joins the tea ceremony and drinks the gyokuro tea, but her memory does not return. However, the two swear to remain friends.
One year later. The “Shuncha Festival” is held in Yokohama City as the main venue. Nagasaki Prefecture, the hometown of Kei Oura, a female businessman from the end of the Edo period who was the first to export Japanese tea overseas, is also a venue, and people from each prefecture where Suzu once brewed her tea stalk truck also attend. Takako, Satono, and Suzu’s cousin, Nozomi Morita, rush to help out, and Sakurai’s book is also released at the venue, making it a major event. The event is a great success, and Suzu is moved to tears.
And today, Suzu still brews tea for many people. [End]
