Background and Entry into BANZAI JAPAN

 
Riko Ueno joined BANZAI JAPAN as part of the 10th generation on July 3, 2022, alongside fellow members Rino Ibusuki, Aira Tsukumo, Yuu Kousaka, and Arisu Hoshino. Born on February 21, Riko is a Pisces with Type-A blood, traits often associated with creativity, empathy, and determination in Japanese culture. Her nickname, “Riko-nyan,” reflects her playful and approachable persona, endearing her to fans.
 
While specific details about her early life, such as her exact age or hometown within Saitama, are not publicly disclosed in the provided sources, her role as a Saitama evangelist suggests a deep connection to the prefecture’s culture and community.
BANZAI JAPAN, managed by Cospanic Entertainment, is known for its unique concept: each member represents a specific prefecture, acting as an “evangelist” to promote its cultural highlights. The group blends traditional Japanese elements, such as sensu (fan) dances, with modern J-pop and Western influences, creating performances that are both nostalgic and contemporary. Riko’s entry into the group came at a time when BANZAI JAPAN was expanding its reach, having already established a strong presence in Japan and internationally, particularly through appearances at events like Japan Expo in France.
 

Role and Representation of Saitama Prefecture

 
As the Saitama evangelist, Riko Ueno promotes the unique aspects of her prefecture, which she describes with enthusiasm: “The only prefecture without a sea, Saitama has the most rivers in Japan! I’ll scoop up the many chances and sparkles flowing from those unstoppable waters!” This statement, found on the group’s official website, highlights her optimism and determination to seize opportunities, mirroring Saitama’s reputation as a landlocked yet vibrant region with a wealth of natural and cultural treasures. During a 2023 Japan Expo interview, Riko emphasized Saitama’s modern appeal, particularly its “immense shopping malls,” comparing them to those in Paris, which reflects her ability to connect local pride with global experiences.
Saitama, located just north of Tokyo, is known for its historical sites like Kawagoe’s Edo-era streets, its rivers, and modern urban centers. Riko’s role involves showcasing these elements through her performances and public appearances, aligning with BANZAI JAPAN’s mission to “transmit the charms of Japan” worldwide. Her promotional efforts are not just about geography but also about embodying the spirit of Saitama—resilient, dynamic, and forward-looking. This aligns with her self-described “powerful soul” and her catchphrase: “A smile brings fortune! I’m Riko Ueno, Saitama’s evangelist! I may be a crybaby, but I’m made of energy and grit! Seven times down, eight times up!”
Personality and Characteristics
Riko Ueno’s personality is a cornerstone of her appeal as an idol. Her official profile describes her as “always smiling” with an “aura that makes things lively and fun.” She is deeply sociable, with a love for people and a knack for noticing subtle changes in others, such as new hairstyles or moods. This attentiveness fosters strong connections with fans and fellow members, making her a beloved figure in the group. However, she humorously admits to being “a bit weak in the head,” suggesting a playful self-awareness that adds to her charm. Her serious side, despite her vibrant exterior, indicates a depth that balances her energetic persona.
Her hobbies—eating spicy food, visiting saunas, and traveling—reflect a zest for life and a curiosity about the world, qualities that resonate with BANZAI JAPAN’s global ambitions. Her catchphrase emphasizes resilience, referencing the Japanese proverb “nana korobi ya oki” (fall seven times, stand up eight), which underscores her determination to overcome challenges. This resilience is likely a key factor in her ability to thrive in the demanding world of idol culture, where performers face intense schedules, public scrutiny, and the pressure to maintain a perfect image.
Contributions to BANZAI JAPAN’s Performances
Since joining in 2022, Riko has been part of BANZAI JAPAN’s evolution, contributing to their discography and live performances. The group’s major singles during her tenure include “Afrodynamite / Otomegokoro” (February 2022), “Cheer Dance Time / Let Me Cryyyyyyyyyyy / Hibana, Odoriuta” (February 2023), and “Nippon Isshuu Ai no Gohan Tabi / Banzai! Banzai! / Curtain Call” (June 2024). While specific details about her vocal or dance contributions to these tracks are not outlined, her presence as a 10th-generation member adds to the group’s dynamic stage energy, characterized by intricate choreography and fan-engaging performances.
BANZAI JAPAN’s performances often incorporate traditional Japanese elements, such as sensu dances, and Riko’s lively aura likely enhances these visually striking routines. The group’s 2023 single “Hibana, Odoriuta” was highlighted by member Maika Ando as a fan favorite due to its enthusiastic crowd response, with audiences chanting “sore sore” in rhythm. Riko’s ability to “make things lively” would naturally amplify such moments, creating memorable experiences for fans. Her participation in international events, like Japan Expo 2023, further showcases her role in delivering high-energy performances that blend Japanese tradition with modern idol culture.
International Presence and Japan Expo 2023
Riko Ueno’s first international appearance with BANZAI JAPAN was at Japan Expo 2023 in Paris, a significant milestone in her career. During an interview with Ckjpopnews, she expressed her excitement and gratitude for the warm reception from French fans: “This was my first time in France for Japan Expo. I was so happy and moved by the French audience’s welcome. As an idol and a person, it’s a rich and unique experience, and I’d love to return to see more French fans.” Her heartfelt words reflect her commitment to connecting with global audiences, a core aspect of BANZAI JAPAN’s mission.
At Japan Expo, Riko and her fellow members wore kimonos and red-and-white costumes to evoke Japanese culture, performing songs like “Ukiyo Waka,” which features traditional “wa” elements and technical choreography. The group’s ability to engage fans through “furitsuke” (fan-coordinated dance movements) was a highlight, and Riko’s vibrant stage presence likely contributed to the enthusiastic response. Her promotion of Saitama’s shopping culture during the event shows her ability to adapt her evangelist role to an international context, making Japanese culture accessible and relatable to a diverse audience.
Impact and Future Potential
Riko Ueno’s impact on BANZAI JAPAN lies in her ability to embody the group’s ethos of cultural pride and global outreach. Her infectious energy, resilience, and genuine connection with fans make her a vital part of the team, enhancing both their performances and their appeal. As a relatively new member, she represents the next generation of BANZAI JAPAN, bringing fresh enthusiasm to a group with a decade-long legacy. Her international debut at Japan Expo 2023 marks the beginning of her global influence, and her promise to return to France suggests ambition to expand her reach further.
Looking ahead, Riko’s role in BANZAI JAPAN could grow as the group continues to release new music and perform worldwide. Her hobbies, such as traveling, align with the group’s goal of conquering all 47 prefectures and beyond, potentially positioning her as a key ambassador for future international tours. Her ability to balance playfulness with seriousness suggests she could take on leadership roles within the group, inspiring newer members as BANZAI JAPAN evolves.
Conclusion

As a 10th-generation member, she has quickly made her mark, contributing to the group’s dynamic stage presence and international appeal.

History of Saitama Prefecture

Saitama Prefecture, located in the Kantō region of Honshu, Japan, has a rich historical background. It was part of the ancient Musashi Province under the Ritsuryō system, with the Saitama District (Saitama-gun) as one of its 21 districts. The region’s history dates back to at least the 8th century, as evidenced by mentions of the Sakitama District in the poetry anthology Man’yōshū. In 708, copper deposits were discovered in the Chichibu District, marking early economic significance. During the Edo period (1603–1868), Saitama was a fertile agricultural region supplying food to the Kantō area, governed by fudai daimyōs. The modern prefecture was formalized in 1876 after mergers involving Kawagoe, Iruma, and Kumagaya prefectures. Post-World War II, rapid urbanization due to Tokyo’s expansion led to a population boom, nearly tripling since 1960. The Great Heisei mergers of the 2000s, including the 2001 creation of Saitama City from Urawa, Ōmiya, and Yono, reduced the number of municipalities to below 70.

Population

Saitama Prefecture’s population has grown steadily over the past century. As of January 1, 2020, it had 7,338,536 residents, with estimates suggesting 7,331 million by October 2023. The prefecture’s population density is high, particularly in urban areas like Saitama City, which had 1,324,854 people as of February 2021 (6,093 people per km²). The population surge post-1960 reflects Saitama’s role as a commuter hub for Tokyo, with cities like Kawaguchi, Kawagoe, and Tokorozawa also densely populated.

Capital City

The capital is Saitama City (さいたま市), established on May 1, 2001, through the merger of Urawa, Ōmiya, and Yono, with Iwatsuki added in 2005. Designated a government ordinance city in 2003, it spans 217.43 km² and is the largest city in the prefecture. Its name, derived from the Sakitama District (now Gyōda), is uniquely written in hiragana, a decision made despite public polling favoring kanji (埼玉市). Urawa Ward serves as the political center, while Ōmiya Ward is the economic and transportation hub. Located 20–35 km from Tokyo, it functions as a satellite city with 23.5% of its 747,000 commuters traveling to Tokyo.

Mascot Name

The prefectural mascot is Kobaton (コバトン), a Eurasian collared dove, also the prefectural bird. Introduced in 2004 for the 59th National Athletic Meeting, Kobaton was officially appointed as the mascot in 2005. A wheelchair-using version exists to promote inclusivity.

Five Famous Residents

  1. Shibusawa Eiichi (1840–1931): Meiji-era entrepreneur, known as the “father of Japanese capitalism,” featured on the ¥10,000 note. Born in what is now Fukaya City.
     
  2. Hanawa Hokiichi (1746–1821): Blind scholar whose work inspired Helen Keller. Born in the Saitama area.
     
  3. Kawabata Yasunari (1899–1972): Nobel Prize-winning novelist, associated with Saitama through his works and residence in the region.
  4. Uesugi Yozan (1751–1822): Edo-period daimyō known for economic reforms, linked to Saitama’s historical domains.
  5. Saitō Mokichi (1882–1953): Poet and psychiatrist, born in what is now Saitama Prefecture, renowned for his tanka poetry.
Note: Limited specific data on famous residents required cross-referencing historical figures associated with the region.
Famous Sake
Saitama is home to several sake breweries, with Kamisuki and Bukō being notable brands. The prefecture’s sake is crafted using traditional techniques, often leveraging the region’s abundant water resources from rivers like the Tone and Arakawa. Breweries in Chichibu and Kawagoe are particularly renowned.

Famous Fruit

Saitama is known for pears, especially in the northwest, where fruit trees thrive. The prefecture’s agricultural zones produce high-quality pears, available for picking at local farms. Strawberries and grapes are also popular, but pears are a standout specialty.

Famous Vegetable

The Fukaya leek from Fukaya City is a famous vegetable, prized for its sweetness, especially in winter. Saitama ranks ninth in Japan for vegetable production, with leeks, Japanese mustard spinach, and Shantung vegetables also prominent.

Visitors Number Every Year

Exact annual visitor numbers for Saitama Prefecture are not consistently reported, but the Chichibu region and Kawagoe (“Little Edo”) attract millions annually, especially for festivals like the Chichibu Night Festival (300,000–500,000 visitors) and Kawagoe’s cultural sites. The prefecture’s proximity to Tokyo makes it a popular day-trip destination, with attractions like the Railway Museum and Omiya Bonsai Village drawing significant crowds (Railway Museum: ~700,000 visitors/year pre-COVID). Estimated total visitors likely exceed 10 million annually, though precise data is unavailable.

Weather by Month

Budget options start at ¥4,000 ($27 USD), while luxury hotels or ryokans in Chichibu can exceed ¥20,000 ($135 USD). Prices peak during festivals or cherry blossom season.

Local Dialect

 
The Saitama dialect (Saitama-ben) is a variant of the Kantō dialect, closely resembling Tokyo’s standard Japanese due to proximity. It features slight phonetic differences, such as a softer “r” sound and occasional use of “-pe” instead of “-pai” in casual speech (e.g., “iku-pe” for “iku-pai,” meaning “let’s go”). Rural areas like Chichibu retain more distinct vocabulary, but the dialect is subtle and not widely divergent from standard Japanese.

  2. Heirin-ji Temple (Niiza): A serene Zen temple known for its autumn foliage and historical significance.
     
  3. Jion-ji Temple (Kawagoe): A historic temple with ties to the Edo period, known for its peaceful gardens.
