This week the Japan Meteorological Agency’s new 酷暑日 (koshobi, extreme heat day) category, for days hitting 40 degrees or more, gets its first real workout. Standing outside watching fireworks is not the move right now. The good news: several events built for air conditioning just opened or are about to, and one of them is literally a pop-up about staying cool.

キンキンキングダム (KinKin Kingdom) at SHIBUYA TSUTAYA

Dates: August 4 (Tue) to August 11 (Tue, holiday), 10:00 to 21:00 Venue: SHIBUYA TSUTAYA 1F, Udagawa-cho 21-6, Shibuya Price: Free entry

The Kingdom 20th anniversary pop-up is a “戦国クールスポット” (Sengoku cool spot): 100-plus 風鈴 (furin, wind chimes) line a corridor printed with quotes from the manga, and you can lift a full-size replica of 王騎 (Ouki)’s spear, about 2 meters and 18 kg, heavier than it sounds. The gallery shows 40 複製原画 (fukusei genga, reproduction artworks) from 20 years of manuscripts, including a first-public-display page of the Zhao general Bankyoku from the current live-action film. Every visitor gets one free cooling item in a special bag, rotating by day: Gatsby body sheets Aug 4-6, Biore cooling towels Aug 7-8, Sea Breeze ice towels Aug 9-11, while stocks last. Goods sales are cashless only, so bring a card or IC payment 公式サイト アニメ！アニメ！.

可愛いだけじゃない!?ピングー展 (Pingu Exhibition) at YURAKUCHO MUSEUM

Dates: July 10 (Fri) to September 6 (Sun), open every day Venue: YURAKUCHO MUSEUM, Tokyo International Forum B1F (1 minute from JR Yurakucho Station) Price: General and university 2,200 yen, junior and senior high 1,650 yen, elementary 550 yen, preschoolers free with a guardian

The debut show of the new YURAKUCHO MUSEUM, which opened in the Tokyo International Forum basement in July, covers the Swiss clay animation series Pingu with original studio notes, storyboards, and the actual miniature clay models used in filming. There is a machine that translates what you say into Pingu’s made-up language, a photo spot themed around the legendary “Pingu’s Dream” episode, and collaboration works by miniature artist Tanaka Tatsuya. Hours extended from August 1: 10:00 to 19:30 (last entry 19:00), and 10:00 to 21:00 on weekends and August 10-14. Some dates, including August 8-16, are timed-entry, so book ahead on eplus if you are set on a specific day 公式サイト ウォーカープラス.

北斗の拳 -FIST OF THE NORTH STAR- 特別企画展 (Special Exhibition)

Dates: August 22 (Sat) to November 8 (Sun), 11:00 to 19:00 (last entry 18:45) Venue: Anime Tokyo Station, Minami-Ikebukuro 2-25-5 (4 minutes from Ikebukuro Station) Price: Free (closed Mondays, or the following day when Monday is a holiday)

Anime Tokyo Station, the Tokyo Metropolitan Government’s anime venue in Ikebukuro, follows its Bleach display (which ends August 16) with a Fist of the North Star special exhibition. It covers the new 2026 anime series with scene photo panels, 設定資料 (settei shiryo, production materials), and a digital “character diagnosis” that tells you which Hokuto character you resemble based on your answers. Free admission makes this an easy add-on to an Ikebukuro shopping day PR TIMES アニメ東京ステーション.

プロジェクトセカイ サマーフェア2026 (Project Sekai Summer Fair) at Animate

Dates: August 8 (Sat) to September 6 (Sun) Venue: All Animate stores in Japan, including Shibuya, Ikebukuro, Akihabara, and Shinjuku, plus the online shop Price: Free entry; 1,100 yen per purchase earns one bonus card

The third round of the Sega x Animate global collaboration project brings a summer fair for Project Sekai: Colorful Stage! feat. Hatsune Miku. During the period, every 1,100 yen (tax included) spent on related goods gets you one 箔押し (hakushi, foil-stamped) illustration card from a set of 26, chosen at random. Overseas stores run a revival of the 2023 only shop at the same time, so Tokyo gets the fair while the international flagships handle the shop. Light, cheap, and a good reason to browse on a hot afternoon PR TIMES.

Book now: ヘタリア20周年原画展 WorldFesta (Hetalia 20th Anniversary Exhibition)

Dates: October 17 (Sat) to October 28 (Wed) in Tokyo, 10:00 to 19:00 (until 17:00 on the final day) Venue: Sunshine City Exhibition Hall A, Ikebukuro (3 minutes from Higashi-Ikebukuro Station) Price: Ticket lottery for the Tokyo run is open now through August 16 on eplus

The Hetalia anniversary exhibition is still two months out, but the Tokyo 先行抽選 (senkō chusen, advance lottery) closes August 16, so this is the week to enter. Hidekaz Himaruya’s original pencil drawings and color illustrations go on display, alongside a life-size Italy figure and photo spots 公式サイト.

Practical notes

All five of these are indoors, which matters this week. Yurakucho connects directly to the Tokyo International Forum basement, and Sunshine City links to Higashi-Ikebukuro without going outside. Bring a card for the Kingdom pop-up, book Pingu’s timed-entry dates, and check each official page before you go, since summer schedules shift.
