HTV-X1 was opened for medias.https://373news.com/news/local/detail/214835/
It is scheduled to make five trips to deliver food, water, experimental materials and other supplies for astronauts by fiscal 2029.

The Flight HTV-X1 manifest includes the delivery of the Intravehicular Activity (IVA) Resuppliable Small Exposed Experiment Platform (i-SEEP) 3B payload. The i-SEEP-3B payload will be extracted robotically from the HTV-X1 vehicle by the Space Station Remote Manipulator System (SSRMS) and Special Purpose Dexterous Manipulator (SPDM) before handoff to the Japanese Experiment Module (JEM) Robotic Manipulator System (RMS) to bring i-SEEP-3B internal via the JEM Airlock (JEMAL). Once integrated with payloads, i-SEEP-3B will be installed on the JEM Exposed Facility (JEM-EF) for future operations at Site 5.

IVA is a spacesuit?
Quote from: Tywin on 06/19/2025 12:39 pmIVA is a spacesuit?No. Like the previous iSEEP platforms, payload swapout is done by the JEM RMS moving the platform to JEM's airlock, the platform being cycled inside, work being done inside JEM, then the platform is cycled back out of the airlock and the RMS remounts it.
In 2009, Canadarm2's first cosmic catch was JAXA's HTV cargo ship. This year, Canadarm2 will catch JAXA's new HTV-X vehicle and berth it to the ISS.
9/ Spetch notes that another Progress spacecraft and NG-23 are launching this fall, with the latter including the first extended Cygnus spacecraft. JAXA will also launch the HTV-X cargo vehicle to the ISS in the fall.
13/ Matsuura says the HTV-X cargo vehicle will be berthed to the ISS and hopes that Yui will be the one to be able to operate the Canadarm2 (sounds like that is still TBD at this point).
HTV-X will launch in October according to today's Crew-10 post splashdown news conference.
Officials plan to launch at least three such HTV-X missions to the ISS. There are tentative plans for a fourth and fifth HTV-X that could launch before 2030. The second HTV-X mission will attempt Japan’s first automated docking with the space station, a prerequisite for any future resupply missions to the Gateway.

Must be 6 month missions back to back.

For Beyond Gravity, there is always excitement when finished products leave our factories. Recently, we sent our second #PayloadFairing and payload support structure (PSS) for Mitsubishi Heavy Industries' H3 launch vehicle from our factory in Emmen, Switzerland, to the Tanegashima Space Center in Japan in support of the next HTV-X mission.Payload fairings are essential components of launch vehicles. They protect satellites during launch and ascent, playing a key role in mission success. With decades of experience and advanced manufacturing capabilities, Beyond Gravity brings Swiss precision and reliability to space programs around the world.The H3 program reflects the strong and trusting partnership between #Switzerland and #Japan. We are proud to support Japan's space program with our technology and strengthen the bilateral relationship between our two countries.Looking ahead to the new year, we look forward to deepening our collaboration with our Japanese partners and continuing to support Japan’s ambitious space goals. 🇨🇭🤝🇯🇵
