"Usmishka" means "smile" in Ukrainian. Led by Hideto "Pika" Chujo on the ground in Ukraine, we support children and women affected by the war and promote exchange between Japan and Ukraine.
ウクライナの子供たちに笑顔を届けたい
We support children traumatized by the war and children suffering from serious illness — visiting pediatric hospitals, holding events at evacuation shelters, and delivering gifts to bring back their smiles.
We deliver relief supplies and help secure housing. In 2025–2026, evacuating residents from dangerous areas has become our main activity. We also provided emergency power after the Kakhovka dam collapse, co-operate a shelter prioritizing people with disabilities, and deliver firewood each winter.
We share Japanese culture — sumo, kendama, origami, and music — with the people of Ukraine, including inviting young Ukrainian sumo wrestlers to Japan's national Wanpaku Sumo tournament.
We strengthen people-to-people ties between Japan and Ukraine and contribute to Ukraine's recovery, operating the "Usmishka" Japan Center at Dnipro National University and building partnerships between universities, municipalities, and organizations.
Since 2023 we have held the Wanpaku Sumo Ukraine tournament every year. Even interrupted by air-raid sirens, the children give their all in the ring — and the winners are invited to the national Wanpaku Sumo tournament in Japan.
"I want to win on the dream stage in Japan and dedicate the victory to my father serving in the army." Your support makes dreams like this come true. The tournaments have been widely covered by Ukrainian media including public broadcaster Suspilne and ICTV.
About the invitation project (JP)Evacuating residents from dangerous areas — work we have continued since the Kakhovka dam was destroyed in 2023 — has become our main activity in 2025–2026. Alongside the evacuation runs themselves, we supply fuel for the evacuation vehicles and cover their repair costs.
"Real heroes don't wear capes — sometimes they wear a Pikachu costume and have an endlessly kind heart."
—— from the Ukrainian humanitarian aid team we work alongside
Their post honoring Hideto Chujo — who fuels their vehicles, joins the evacuation runs and supports children — drew over 1,000 likes and many messages of thanks from people across Ukraine. See the post on Instagram.

He has continued supporting the people of Kherson since leaving office. We currently work in Kherson in coordination with the Deputy Governor. See the post.

Held March 8 at the Olympic Reserve Stadium in Dnipro — from building the ring to the awards ceremony — and covered nationwide by Suspilne, ICTV and live TV.
Responded to requests from Zaporizhzhia authorities and fellow aid workers, travelling to areas damaged by Russian shelling and flooding; also helped repair damaged homes near the Dnipro hydroelectric plant, which is located in the city of Zaporizhzhia.
Egor (Mykolaiv) and two others competed at Ryogoku Kokugikan. Emergency donations supported Kyiv's Okhmatdyt children's hospital after it was struck in July.

After signing a memorandum of understanding with Oles Honchar Dnipro National University on July 25 (article), the Ukrainian-Japanese Center opened on campus on October 27 (article). Working with the Ukraine-Japan Center in Kyiv, it offers Japanese language classes, calligraphy lessons and other cultural programs.
Winners of the 3rd Ukraine Children's Sumo Usmishka National Tournament were selected for Japan's Hakuho Cup; Makar returned to Japan for a second time.
Evacuations from dangerous areas, continued since the 2023 Kakhovka dam collapse, became our central work in 2025–2026 — including fuel and vehicle-repair support for evacuation transport. See the post.
Each winter, when electricity and heating are unstable, we deliver firewood to villages in rural areas. See the post.
Awarded for our humanitarian work by Minister Denys Uliutin of the Ministry of Social Policy, Family and Unity, who also heads the government's humanitarian support team. See the post.

Working with the Ukrainian Sumo Federation, completed a national tournament for children and students despite air-raid interruptions. Regular visits to Okhmatdyt children's hospital continue, including making good-luck badges with children before surgery.
Fighting still continues in the east and south. Supply runs, hospital visits, cultural exchange — under one motto: "May every child live a happy childhood."

"May every child live a happy childhood." Near-daily reports from the ground in Ukraine.

Follow @ChujoPikaWe want to provide support from the ground-level perspective that governments and international organizations find difficult. Saving children deprived of a safe living environment by war and violence requires not only systems and care, but face-to-face relationships. Cultural exchange also encourages children emotionally and helps their potential grow. We support Hideto Chujo's work on the ground and use ICT to deliver support from Japan to the children of Ukraine. Thank you for your understanding and cooperation. — Nagaaki Kamada, Chairman
