Miracle Pine Seeds to Be Stored in Britain
Seeds from the lone pine that survived Japan's 2011 tsunami will be sent to the Millennium Seed Bank by the end of 2026.
Updated on Nov. 5, 2026 in Botany
Seeds from the miracle lone pine in Rikuzentakata, the only tree on its beach to survive the 2011 tsunami, are scheduled to be sent to Britain for storage at the Millennium Seed Bank by the end of 2026. The original tree died in May 2012 after seawater rotted its roots.
Why it matters
The project aims to pass down the memories and lessons of the disaster, and the storage agreement with the Millennium Seed Bank was finalized in May 2026. The seed bank preserves about 15% of the world's plant species, giving the pine's genetic line a secure long-term home.
Of roughly 200 grafting attempts, only three saplings took root, and the team has cultivated the genetically identical successors over nearly 15 years. The exact genetic survival rate and long-term germination success of the stored seeds remain unknown.
The players
Millennium Seed Bank
The Millennium Seed Bank at Wakehurst in Sussex, operated by Kew, is one of the world's largest plant seed conservation facilities, preserving about 2.5 billion seeds from roughly 40,000 species.
Sumitomo Forestry
Sumitomo Forestry is a Tokyo-headquartered Japanese forestry and construction company that led the grafting and cultivation effort to propagate the pine's successor saplings.
The details
Team members collected branches from the lone pine standing amid the debris, authorized by the municipal government, and attached cuttings to the living branches of another established pine through grafting. Sumitomo Forestry grew successor saplings and harvested seeds from one sapling in October 2025, and the seeds are scheduled to reach Britain by the end of 2026.
Timeline
April 2011: Preservation campaign began about a month after the disaster.
May 2012: The original pine was confirmed dead after seawater rotted its roots.
October 2024: Kew approached Sumitomo Forestry again about seeds.
October 2025: A substantial batch of seeds was harvested from one sapling.
May 2026: Storage agreement with the Millennium Seed Bank was finalized.
The Big Picture
The transfer extends the Millennium Seed Bank's mission of safeguarding about 15% of the world's plant species into a single, disaster-linked lineage. It shows how grafting, a technique with a roughly 2,000-year history, can carry a tree's genetics forward after the original is lost.
Seed deposits held at the Millennium Seed Bank can be used by researchers to study the pine's genetic traits and to support future propagation. Readers interested in how the lineage is preserved can follow the annual deposit schedule over the coming years.
The takeaway
Preserving a single resilient tree's genetics shows how grafting and seed banking can keep a disaster's living memory alive. Careful propagation over many years turned three successful grafts into a lasting legacy.
What happens next
The seeds are scheduled to be sent to Britain by the end of 2026, with about 200 seeds to be deposited annually over the next five years or so.
