Three Years of Volleyball and Sendai Sweets
Kasho Sanzen is the Sendai confectioner behind Hagi no Tsuki, a fluffy castella cake wrapped around custard cream and one of Japan's best-known regional souvenirs. Haikyu!! sets part of its story in Sendai, and the two have run annual collaborations since 2024. This year marks round three.
The pairing started in 2024 with middle blocker Kei Tsukishima fronting Hagi no Tsuki. In 2025, Toru Oikawa joined through the company's zunda dessert brand Zunda Saryo (zunda is sweet mashed edamame paste, a Miyagi staple). The special packages with newly drawn character art went on sale in Sendai first, then at a JR Tokyo Station pop-up this June that the company says drew a big response. The Haneda run is billed as the second round of that revival.
For 2026, the collab expands to Date Tech High: Takanobu Aone and Kenji Futakuchi will front the company's Date Emaki sweet, which shares the Date name with their school. That lineup arrives later this summer, but the Haneda event sticks to the Tsukishima and Oikawa items.
What's on Sale at Haneda
According to Kasho Sanzen's PR TIMES release, the pop-up runs July 17 to July 31, 2026 at the 2F Marketplace event space in Terminal 2, under the north stairway, open 6:30 a.m. to 8:00 p.m.
The lineup:
- Haikyu!! Hagi no Tsuki special package (2025 version): five cakes for ¥1,690, in the Tsukishima box. The 2024 and 2026 package designs are not part of this sale.
- Haikyu!! Sendai zunda mochi special package: eight pieces for ¥1,550, with the 2025 Oikawa art.
- Haikyu!! Zunda Shake Toru Oikawa: a vanilla shake blended with Zunda Saryo's zunda paste, ¥630 takeout, served with an Oikawa straw tag. This one is sold only at the Zunda Saryo shop in Terminal 2's 3F Food Plaza, open 9:00 a.m. to 6:00 p.m.
- 20 kinds of collab goods, plus a ¥100 limited shopping bag featuring both Tsukishima and Oikawa.
Quantities are limited, and the company warns purchase limits may apply. No other collab items beyond the listed lineup will be sold at the venue.
The release frames the airport choice directly: Haneda is Japan's gateway for international travelers, and the company wants a Sendai-born project in front of Haikyu!! fans from both inside and outside Japan.
Looking Ahead
After the Haneda run closes July 31, the next stop is Sendai. A companion Kasho Sanzen release says the new Date Emaki collab with Aone and Futakuchi goes on sale August 11, 2026 at JR Sendai Station.
There is plenty of anime on the horizon too. The release notes that the sequel film Haikyu!! VS The Little Giant, covering Karasuno's quarterfinal against Kamomedai, and the special anime Haikyu!! Bakemono-tachi no Iku Tokoro (roughly "Where the Monsters Go"), covering Fukurodani vs. Mujinazaka, are both in production. The official site has since dated both for 2027. They follow 2024's Haikyu!! The Dumpster Battle, which grossed over ¥20 billion (approx. $130 million) worldwide and took an Excellent Animation of the Year prize at the Japan Academy Film Prize.
For fans outside Japan, the TV anime streams on Crunchyroll and Netflix, and Haruichi Furudate's original manga, now past 75 million copies in circulation, is published in English by Viz Media. The sweets, for now, require a trip through Haneda.
