The Yomiuri Shimbun
A stage rehearsal is taken place by means of IOWN at the 2025 Osaka-Kansai Expo venue in Konohana ward, Osaka, on Saturday.
Performers from a venue at the 2025 Osaka-Kansai Expo and an another venue in Taiwan act together by means of Innovative Optical and Wireless Network, a next-generation communications infrastructure, on Saturday and Sunday.
IOWN is characterized by its ability to transmit large volumes of data at high speed with low latency. It was provided by Nippon Telegraph and Telephone Corp. to link the two venues, which are approximately 3,000 kilometers apart.
At the Expo site in Yumesima, Osaka Prefecture, Kabuki actor Shido Nakamura and virtual singer Hatsune Miku performed, while at the Taiwanese site, a traditional performing arts group took to the stage. Lighting effects were integrated, with each screen projecting performers dancing and fighting together despite being far apart, creating a sense of unity in the performance.
This was the first time that an initiative utilizing IOWN was established between Japan and Taiwan. During a rehearsal similar to the real stage, which was open to the press on Saturday, the round-trip communication time was 0.04 seconds.
'The performance, in which the lighting, sound and movements of the performers were perfectly synchronized, is a fruits of technology that only IOWN can deliver.,' Akira Shimada, president of NTT said.

Over 260 Japanese National Treasures Featured at Special Exhibitions in Osaka, Nara, Kyoto Held to Coincide with Expo 2025
OSAKA — With the occasion of the 2025 Osaka-Kansai Expo, art galleries and museums throughout the Kansai region held special exhibitions, displaying Japan's finest pieces and putting new spins on them, with three museums in Osaka, Nara and Kyoto recently exhibiting national treasures. More than 260 national treasures, or about 30% of all the national treasures in the country excluding structures, were displayed, providing a rare opportunity to view a large number of masterpieces. 135 national treasures in OsakaThe largest number of national treasures — 135 items — were displayed at the National Treasures of Japan exhibition at the Osaka City Museum of Fine Arts. The exhibition featured treasures that are representative of Japanese art history and mentioned in school textbooks, such as 'Deep Vessel with Flame-Style Pottery' from the Jomon period, which was excavated in Tokamachi, Niigata Prefecture, and the seated Ganjin Wajo statue, a masterpiece sculpture of the highly ranked monk owned by Toshodaiji temple in Nara. The paintings of birds and flowers on fusuma room partitions by Kano Eitoku, a painter of the Azuchi-Momoyama period (late 16th century), were ink wash paintings and part of a series of paintings at Jukoin temple in Kyoto. Eitoku used ink lines of varying sizes to depict a huge old plum tree twisting and turning, creating a spring scene full of life on the four fusuma partitions displayed at the museum. A variety of treasures, including writings and swords, were exhibited with national treasures that have been repaired with financial assistance from the Tsumugu Project, a joint undertaking by the Cultural Affairs Agency, Imperial Household Agency and The Yomiuri Shimbun. They included 'Bound Fan Papers with the 'Lotus Sutra'' from Shitennoji temple in Osaka, which depicts the lives of nobles and commoners and is a copy of the Lotus Sutra, and the 'Fugen Bosatsu (Samantabhadra)' owned by the Tokyo National Museum, a work considered one of the greatest masterpieces of Buddhist painting. The Osaka City Museum of Fine Arts reopened in March after undergoing a major renovation, in which work was done to lower the display stands and reduce reflections on the glass cases. 'We have taken great care to make the works easier to view,' said museum director Sakae Naito. The exhibition didn't have a specific theme; instead, it was meant to provide visitors with an opportunity to enjoy the richness of Japanese art more freely in a better environment. Eitoku's masterpiece 'Chinese Lions,' which is owned by the Museum of the Imperial Collections, Sannomaru Shozokan, and the dogu figurine known as 'Jomon Venus' excavated in Chino, Nagano Prefecture, were displayed. Ogata Korin's masterpiece 'Irises' of the Nezu Museum in Tokyo was also exhibited. Nara exhibition on Buddhist, Shinto art The Nara National Museum in Nara, which specializes in Buddhist art, held an exhibition titled 'Oh! Kokuho: Resplendent Treasures of Devotion and Heritage,' focusing on Buddhist and Shinto art. The exhibition, held to celebrate the museum's 130th anniversary, featured about 140 artworks, including 112 national treasures. Exhibits included 'Standing Kannon Bosatsu (Sk. Avalokitesvara; also known as Kudara Kannon)' from Horyuji temple in Nara Prefecture, which was created during the Asuka period (592-710) and is one of Japan's earliest wooden sculptures, and 'Seated Dainichi Nyorai' by Unkei, which is owned by Enjoji temple in Nara. Buddhist statues mainly from the Kansai region and those as far as from Tokyo and Hiroshima Prefecture were also displayed. The dignified expression and posture of the finely sculpted 'Seated Bosatsu with One Leg Pendant' from Hobodai-in Gantokuji temple in Kyoto created a tense atmosphere. The exhibition also displayed 'Seven-Pronged Sword' of Isonokami Jingu shrine in Nara Prefecture, an iron sword from the Kofun period with six branch blades, as well as Buddhist paintings and sumi ink writings, allowing visitors to trace how different religions gained acceptance by people and how they have changed. 'Seated Bodhisattva with One Leg Pendant' from Chuguji temple in Nara Prefecture and other artworks were also exhibited. The Yomiuri Shimbun'Standing Kannon Bosatsu (Sk. Avalokiteshvara; also known as Kudara Kannon),' owned by Horyuji temple in Nara Prefecture, exhibited at the Nara National Museum in NaraThe Yomiuri Shimbun'Seated Bosatsu with One Leg Pendant,' owned by Hobodai-in Gantokuji temple in Kyoto, exhibited at the Nara National Museum in NaraKyoto exhibition on cultural exchange The Kyoto National Museum's special exhibition 'Japan, an Artistic Melting Pot' shed light on cross-cultural exchanges and Japanese art. The exhibition traced this history with about 200 artworks, including 19 national treasures and 53 important cultural properties. Among them was 'Wind God and Thunder God Screens' by Tawaraya Sotatsu, a national treasure owned by Kenninji temple in Kyoto. World expositions can be viewed as an example of cross-cultural exchange. The Meiji government compiled the first Western-style history of Japanese art, consisting of works it wanted to show to the world, to coincide with Japan's participation in the Expo 1900 Paris. This exhibition displayed some of the works listed in the book, including the dotaku bell-shaped bronze, an important cultural property that was excavated in Yasu, Shiga Prefecture. Exhibits also included the ukiyo-e woodblock print by Katsushika Hokusai 'Under the Wave off Kanagawa' from the series 'Thirty-six Views of Mount Fuji,' which is also popular in the West, as well as Buddhist statues, landscape drawings, paintings of flowers and birds, which indicate Japan's exchanges with East Asia, and ceramics.

2025 Osaka Expo: Akita Pref.'s Omagari Fireworks to be on Display on June 28
Yomiuri Shimbun file photo Pyrotechnic artwork launched during last year's Omagari Fireworks Festival in Daisen, Akita Prefecture. AKITA — Pyrotechnic artworks from the famous Omagari Fireworks Festival in Daisen, Akita Prefecture, will illuminate the night sky over the 2025 Osaka-Kansai Expo venue on June 28. This will mark the first time that the pyrotechnicians behind one of Japan's three major fireworks festivals will travel to the Kansai region to set off fireworks. 'We want to show people from Japan and abroad the beauty of fireworks,' fireworks specialist Tadanobu Komatsu, 61, said. They will display fireworks as part of the Japan Fireworks Expo, where pyrotechnicians from all over the country will gather to showcase their work at the Kansai Expo. The Omagari Chamber of Commerce and Industry, the organizer of the local fireworks festival, was approached last October about participating in the Expo event. Komatsu and his colleagues readily agreed, calling it 'an honor to shoot off fireworks at the Expo.' Held every August, the Omagari Fireworks Festival attracts 100,000 spectators and involves 28 fireworks companies from Daisen and other regions in Japan. Each display is scored, and the participating companies rotate every five years based on their rankings. Last year, Komatsu Fireworks Co., headed by Komatsu, won the Prime Minister's Prize, the highest honor. 'It's a competition where the best pyrotechnics are brought together, and that's why fireworks at Omagari festival are considered the pinnacle of the art,' Komatsu said. On June 28, the Omagari Hanabi Design Team, comprising of Komatsu Fireworks and three other fireworks companies from Daisen, will shoot off fireworks from the southern embankment of Yumeshima Island in Osaka's Konohana Ward. The team will showcase about 800 fireworks, including the most difficult 'goeshin' firework which consists of six layers of concentric circles spread evenly; 'happosaki,' which shoots light rays in various colors in a circular pattern from the center; and 'senringiku,' which explodes with a countless number of small bursts. Komatsu went to Yumeshima in advance to confirm the launch positions. 'The fireworks of Omagari are still not well known in western Japan. We want to put on a show that will make people want to visit Omagari,' he said. Fireworks at Expo The Japan Fireworks Expo will feature eight fireworks displays during the 2025 Expo. Two displays have been held so far: the Ise Shrine Dedication National Fireworks Display from Mie Prefecture on April 26 and the Futaba Fireworks from Fukushima Prefecture on May 31. The Ise display attracted 104,803 people, and the Futaba display brought a record 169,923, leading the Japan Association for the 2025 World Exposition to limit the number of spectators allowed to ascend the venue's Grand Roof (Ring) for viewing. The Omagari fireworks display on June 28 is also expected to draw large crowds, so the association will dispatch more security personnel than usual to control the crowds during the event. The June 28 display will be followed by the other famous displays on July 21, Aug. 23, Sep. 27 and Oct. 8, though details have not yet been announced. Fireworks from various regions will be launched jointly on July 23.
