Krysten Coombs' badminton bronze was Great Britain's 124th and final medal from TokyoGreat Britain's team have "rewritten the history books" with their performance in Tokyo, says ParalympicsGB's chief Penny Briscoe.
GB won 124 medals, including 41 golds, to finish second in the medal table behind China.
While those tallies are a drop on Rio five years ago, Britain won medals in 18 of the 19 sports they entered, a new team record.
"It's been an incredible Games for ParalympicsGB," Briscoe said.
"We're absolutely delighted with the performance of the team."
Chef de mission Briscoe believes the return of Russian athletes - competing under the flag of their Paralympic Committee after they were banned in 2016 - made replicating Rio's medal totals improbable.
Britain won 64 golds and 147 medals overall in Rio after claiming 34 and 120 respectively at London 2012.
She told BBC Radio 5 Live: "The medal total was always going to be difficult in terms of the return of Russian athletes. But for 18 out of 19 sports to deliver medal success was an absolutely phenomenal effort by the team.
"We've rewritten the history books out here in Tokyo."
The Winter Paralympics begin in Beijing in six months' time with the next edition of the summer Games in Paris only three years away.
"It has been a monumental effort," said Briscoe of the Tokyo campaign. "It has been challenging, complex and incredibly demanding. Not only in the 12 days we've been competing but in the 18 months leading up to the Games."
Paralympic movement 'stronger than ever'
The staging of the Games amid a continuing global pandemic has shown the Paralympic movement is "stronger than ever before", according to International Paralympic Committee (IPC) president Andrew Parsons.
The Games, like the Olympics earlier in the summer, took place behind closed doors with Covid-19 case numbers in Japan breaching 25,000 per day for the first time four days before their start.
"I think these Games were just sensational," he said.
"The sport was unbelievable, world records were broken in every possible sport. Performances were fantastic. To think that these athletes have prepared for these Games under the circumstances of the pandemic, facing restrictions, is unbelievable.
"It's proof that the Paralympic movement is stronger than ever before."
Parsons hopes to have all sports shown live in 2024
Financial constraints meant that there was no live television coverage of wheelchair fencing, powerlifting and Para-taekwondo at the Tokyo Games.
Parsons said he hoped to have live coverage of all sports at Paris 2024.
"In Rio there were 13 events covered live and here in Tokyo we are running 19 sports live," he told BBC Radio 5 Live.
"Of course we would like to have the 22 sports being played live on TV but at the end of the day it's a matter of resources and broadcasting rights.
"I was frustrated to not be able to have these sports live but also on the flip side we made great progress from going from 13 in Rio to 19 here in Tokyo."
Parsons added that the IPC will take "a more targeted approach" in adding new sports to the Paralympic programme after seeing the response to karate, baseball, skateboarding, climbing and surfing at the Tokyo Olympics.
The Paris 2024 sports selection mirrors Tokyo, although wheelchair basketball is still waiting for final confirmation that it will be included because of changes to its classification rules that have been demanded by the IPC.
Any significant changes to the Paralympics programme would only take effect from Los Angeles 2028.
"We will be more proactive in selecting sports that we think will be appealing or that the host nation might think will be interesting," Parsons said.
Headline Storey writes new chapter
Sarah Storey first competed at the Paralympics at Barcelona in 1992Sarah Storey delivered three of Britain's golds with victory in the individual pursuit, time trial and road race to claim her 15th, 16th and 17th Paralympic titles of a career that has spanned eight Games and two sports.
Storey has now surpassed swimmer Mike Kenny as the most successful British Paralympian of all time.
While the 43-year-old intends to compete again at Paris 2024, in part to give her three-year-old son Charlie the chance to experience the Paralympics in person, other British legends will not be back next time.
Five-time champion swimmer Ellie Simmonds and Libby Clegg, who did the T11 sprint double on the track in Rio, have said that Tokyo marks the end of their Paralympic careers.
However, a new generation of stars emerged, led by swimmer Reece Dunn, who was Britain's most successful athlete at the Games, winning five medals, including three golds.
