日本郵局於 2021 年推出的「寶可夢郵票BOX～寶可夢卡牌遊戲 回眸美人圖・月亮與雁套組～」，是結合日本傳統美術、郵政文化與寶可夢卡牌遊戲（PTCG）的話題性限定商品。此商品正式名稱為「ポケモン切手BOX 見返り美人 月に雁セット」，自消息公開以來便引發收藏界與卡牌玩家的高度關注，也成為近年最具代表性的官方聯名紀念商品之一。

這款郵票BOX的設計靈感，來自日本浮世繪大師菱川師宣的經典作品《見返り美人圖》，以及江戶時代廣為流傳的花鳥畫題材《月に雁》。日本郵局巧妙地將這兩幅極具文化象徵性的藝術作品，與寶可夢角色融合再創作，分別化為兩張專屬宣傳卡牌：以《見返り美人圖》為構圖基礎的「皮卡丘」PROMO卡，以及以《月亮與飛雁》意象重新詮釋的「烏烏（ウッウ）」PROMO卡。這種將傳統藝術與現代流行文化結合的方式，不僅讓寶可夢卡牌跳脫單純遊戲用途，更提升至文化收藏品的層次。

商品的發行時間訂於 2021 年 8 月 25 日之後，初期販售方式並非一般通路上架，而是採取郵便局限定的抽選販售制度。這樣的安排，主要是為了因應可能出現的搶購潮與轉賣亂象。日本郵局同時開放「明信片抽選」與「官方網站抽選」兩種方式，讓民眾報名參加。明信片抽選的截止日為 2021 年 9 月 10 日（以郵戳為準），WEB 抽選則開放至 9 月 15 日晚間。所有中選者，均會在 10 月中旬左右收到實體中選通知書，並於 10 月下旬至 11 月中旬之間，前往申請時指定的郵局窗口完成購買。

在抽選流程中，申請者必須填寫完整的個人資料，包括郵遞區號、住址、姓名、假名、聯絡電話，以及指定欲取貨的郵局名稱與對應的申請編號。這樣嚴謹的流程，也反映出日本郵局對公平性與實名制購買的重視。隨著申請人數遠超預期，官方於 7 月 21 日宣布，原本規劃的 8 萬組發行量已不足應付需求，最終追加 2 萬組，總發行量提升至 10 萬組，但即便如此，依舊無法滿足市場熱度。

在內容物方面，這款郵票BOX的配置相當豐富。套組內含一組限定紀念郵票、三張特殊造型卡片、一本「寶可夢卡牌遊戲 劍與盾 いつでもどこでも 家庭向卡牌遊戲」，以及最受矚目的兩張 PROMO 卡——《回眸美人皮卡丘》與《月亮與雁烏烏》。所有物品皆收納於印有精靈球圖樣的原創設計收藏盒中，整體質感與完整度極高，明顯是以收藏市場為主要定位。

此外，日本郵局也曾於 2021 年 8 月 25 日至 8 月 30 日，在「日本國際切手展 2021」會場限定販售相同內容的版本，讓部分無法參與抽選的收藏者仍有機會現場購入。官方定價為日幣 4,000 圓（含稅），但由於數量有限、題材獨特，加上 PROMO 卡無法單獨取得，上市後在二級市場的價格迅速飆升，成為寶可夢卡牌收藏史上極具代表性的郵局限定商品之一。

整體而言，「寶可夢郵票BOX～回眸美人圖・月亮與雁套組～」不僅是一款卡牌周邊，更是一次成功的文化跨界實驗。它將日本傳統藝術、國家郵政系統與全球最具影響力的IP之一完美結合，也象徵著寶可夢品牌已從娛樂產品，進一步延伸至藝術收藏與文化象徵的層級。

The Pokémon Stamp Box ~ Pokémon Trading Card Game “Looking Back Beauty” & “Wild Geese Flying Under the Moon” Set, released by Japan Post in 2021, is a highly talked-about limited-edition product that combines traditional Japanese art, postal culture, and the Pokémon Trading Card Game (PTCG). Officially titled “ポケモン切手BOX 見返り美人 月に雁セット”, this release attracted enormous attention from both card players and collectors upon announcement, and is now regarded as one of the most iconic official collaboration collectibles in recent years.

The concept of this stamp box is inspired by classic Japanese ukiyo-e art. One reference is “Mikaeri Bijin” (Looking Back Beauty) by renowned ukiyo-e artist Hishikawa Moronobu, while the other draws from the Edo-period bird-and-flower motif “Tsuki ni Kari” (Wild Geese Under the Moon). Japan Post reinterpreted these culturally significant artworks by integrating Pokémon characters into the compositions, resulting in two exclusive promotional cards: a Pikachu promo card based on Looking Back Beauty, and a Cramorant (ウッウ) promo card inspired by Wild Geese Under the Moon. This fusion of traditional fine art and modern pop culture elevated the Pokémon cards beyond simple game items, positioning them as cultural collectibles.

The product was released on and after August 25, 2021, and unlike standard retail items, it was distributed primarily through a lottery-based sales system exclusive to post offices. This approach was intended to manage overwhelming demand and discourage scalping. Japan Post offered both postcard-based lottery applications and online lottery entries. The postcard applications closed on September 10, 2021 (postmark valid), while the web lottery remained open until September 15, 2021. Winners received physical notification letters around mid-October and were required to complete their purchases in person at their selected post office between late October and mid-November.

Applicants were required to provide full personal details, including postal code, address, name, phonetic reading, contact number, and the designated post office for pickup along with its application number. The strict application process reflected Japan Post’s emphasis on fairness and identity verification. Due to demand far exceeding expectations, Japan Post announced on July 21 that the original production run of 80,000 units would be increased by 20,000, bringing the total to 100,000 units. Even so, the supply was still insufficient to meet market demand.

In terms of contents, the stamp box offered an impressive and well-curated lineup. The set includes a limited-edition commemorative stamp sheet, three specially shaped cards, the “Pokémon Card Game Sword & Shield – Play Anytime, Anywhere Family Card Game”, and the two highly anticipated promo cards: “Looking Back Beauty Pikachu” and “Wild Geese Under the Moon Cramorant.” All items are housed in a custom-designed original storage box featuring a Poké Ball motif, emphasizing both presentation quality and collectability.

In addition to the lottery sales, Japan Post also sold the same set during the Japan International Stamp Exhibition 2021, held from August 25 to August 30, 2021, allowing a limited number of visitors to purchase the product on-site. The official retail price was 4,000 yen (tax included). However, due to limited supply, unique artistic themes, and the exclusivity of the promo cards—which cannot be obtained separately—the set’s value rose rapidly on the secondary market after release.

Overall, the Pokémon Stamp Box ~ Looking Back Beauty & Wild Geese Under the Moon Set represents more than just a card game accessory. It stands as a successful example of cultural crossover, seamlessly blending traditional Japanese art, a national postal institution, and one of the world’s most influential entertainment franchises. The release symbolizes how the Pokémon brand has evolved beyond gaming into the realms of art, heritage, and high-end collectible culture.
