       In the Imperial Bonsai Collection there are more Japanese red pine (Pinus densiflora, aka-matsu) than Japanese five-needle white pine (Pinus parviflora, goyō-matsu) bonsai.  (Although red pine has long been popular, it is a difficult bonsai to create and care for in a container to simulate its original taste and appearance as in nature with its smooth, reddish bark, fine twigs, and the green color of its soft, long needles.  Bonsai of five-needle pine -- which imitated the appearance of red pine in nature and had more compact needles -- were created and became popular, instead, as were also naturally tasteful Ezo spruce (Picea glehnii, aka-ezomatsu).  The red pine bonsai nearly disappeared outside the Imperial Collection.) 8  One of Japan's National Treasures is the 73 cm (29") high and five hundred and fifty-year-old Sandai-Shōgun-no-matsu ("Third generation Tokugawa's pine," var. Negishi, goyo-no-matsu) whose rugged trunk is now hollow.

       Except for the Imperial Household Agency headquarters building and the 52-acre East Gardens (Higashi Gyoen), the palace is generally closed to the public.  While the Bonsai Collection is not open to the public, over the years a few groups of visiting bonsai enthusiasts from overseas have been allowed private tours of the Ōmichi Bonsai Shitate-ba.  The area with its orderly rows of shelves occupies approximately 480 square meters (5,100 sq. ft.).  The entire flat ground of the Bonsai Shitate-ba of about 8,000 sq. m. (roughly 2 acres), however, is not limited to bonsai alone but includes the growing of wild plants collected by the late Shōwa Emperor (Hirohito) himself.  (On fine, calm days that Emperor would enjoy a stroll in the area and sometimes look in at the Shitate-ba to see how his plants were growing.)  Near to where the bonsai are kept, there are greenhouses for tropical plants and orchids, and beds where the flowers of each season are cultivated.  Here, too, are the storehouses where countless varieties of bonsai never seen outside the palace are collected and stored and where they rest peacefully with the spirits of the artisans who created them.  There are some large-sized bonsai which we don't usually see, and also the dwarf trees in Kōkyo are each kept with their natural character.  The caretakers pay special attention not to spoil each tree's character.
       The Ōmichi Teien Garden has about 600 bonsai pieces of some 90 species of plants.  The oldest tree is said to be a 600 year-old shimpaku which the Meiji Emperor bought.  The Imperial Bonsai are cared for by the Gardens Section of the Imperial Household Agency's Maintenance and Works Division. 9

Transporting a 250-year-old pine
"The years weigh heavy on [eight] imperial gardeners straining to transport a 250-year-old pine.
The bonsai, one of 350 in the Emperor's collection, will greet guests visiting the palace for a state banquet."

       "A network of monofilament lines stretched like a spider's web above Mr. [Fumio] Iizuka's bonsai garden to keep the [jungle] crows [(Corvus macrorhynchos)] from roosting in the plants.  Centuries old, these trees had been lovingly tended to maintain their twisted shapes.
       "'You won't see the outcome of what we're doing to this branch for 20 years,' said Mr. Iizuka, [a mild-mannered man in glasses and shirtsleeves who oversees the Emperor's spectacular bonsai collection] squinting at the raw limb of a red pine.  'You have to be patient in this business.'
       "As he talked, his hands never stopped picking at needles or leaves, reminding me of a mother absently smoothing her son's cowlick.  We paused at the end of a row beside a 400-year-old pine, known as the Crab Tree.  'It was originally shaped like a crab,' said Mr. Iizuka, holding out his arms to demonstrate.  'But, sorry to say, one of the branches died, so now it's a one-armed crab.  It was quite a sight in its day,' he said, sighing as if remembering an old love.
       "Here at the center of the palace grounds, walking among the years of carefully considered garden work, it was easy to forget that we were also at the center of Tokyo.  A long-dead bonsai man tended that pine in the days when samurai roamed the land; another, that juniper before Portuguese landed ships at Kyushu; another, that maple when the Emperor was still considered a god.  There was a different sense of time here, rooted deep in tradition.  Nobody with a Palm Pilot and a production schedule was looking over Mr. Iizuka's shoulder.
       "'It's hard to find people who appreciate this relaxed approach to things,' he said, stopping beside the garden's oldest resident, a 600-year-old juniper.  'I get a lot of pleasure when our plants are shown at the Emperor's garden party.  I feel like they are my children.'" 10

       "Morning rain glistens on a venerable maple, one of 350 bonsai in the private gardens of the Imperial Palace.  In such potted landscapes mossy rocks suggest mountain ranges, while twisted trees represent those sculpted by wind and weather.
       "'Unless you love bonsai, you can't work here,' says Fumio Iizuka, [now retired] assistant manager of the Imperial Garden Department.  'You have to be willing to work with them all day long, to figure out when they need water, when they need to be turned toward the sun.  Each one has its own aura, to which you need to be attuned.  You can't say one is better than another because it is shorter or taller than most.  We have many different kinds of trees, just as we have many different kinds of humans.  You have to accept each one on its own terms.'" 11

       "The Imperial Bonsai are so far beyond the conditions laid down for bonsai in general that the impression they give is one of sheer wonder...  Human artifice has been held down to the utmost limit...  Grave, stately, preserving nature as it is, with luxuriant foliage yet small branches, all that strikes the eye about a great bonsai is due to the special Palace way of making bonsai, so different from ordinary cultivation.  The trees in the Imperial Bonsai Collection have an average age over one hundred years... and trees several hundred years of age are far from rare... steeped in an intensely profound grandeur that cannot be found in just ordinary bonsai." 12

       A 380-year old Japanese black pine var. Kashima (Pinus thunbergii var. Kashima, kuromatsu) provided a background for thousands of photographs taken by visitors when the government first placed this bonsai on display at Expo '70.  (Kashima in Ibaraki Prefecture is a little ways to the northeast of the Tokyo area.  The Ōsaka World Exposition in Senri was the first such exposition to take place in Asia.  The theme of Expo '70 was "Progress and Harmony of Mankind."  Its special features were the many exhibitions and film and slide presentations about space technology.  Seventy-seven countries participated and over sixty-four million visitors attended.)  The tree's 135 cm (54") high majestic curved trunk and generally imposing air was definitely at home in a container with the chrysanthemum insignia -- it belongs to the Imperial Family.  A considerable number of naturally occurring kuromatsu were discovered at Kashima during the Meiji and Taishō eras, but few survive today.  This one is especially valuable for its venerable aspect.  It is invariably brought out at the Imperial Palace to mark visits by state guests. 13

       In May 1972, from the 14th to 28th, the California Bonsai Society held its 15th Annual Exhibition.  This was in conjunction with the 50th Anniversary of the Museum of Science and Technology which sponsors the event.  There was a special feature showing of loaned bonsai from the Japanese Imperial Household for this event. 14

       The post-war concerted effort to save and restore the Imperial Collection finally made it possible, in 1974, to put the trees on display at a special showing held in Tokyo to mark the golden anniversary of the Emperor and Empress.  The display was attended by more than seventy thousand visitors. 15

       In March 1975, Japan gave the U.S. a Bicentennial gift of fifty bonsai -- one for each state.  Half the miniature trees were donations from private sources, plus three extra from members of the Royal Japanese Family: No. 51 and 52, a Japanese hemlock (Tsuga diversifolia, tsuga) and Trident maple (Acer buergerianum, kaede), respectively, gifts from Princess Chichibu (1909-1995, wife of Hirohito's younger brother) and Prince Takamatsu (1905-1987, Hirohito's second younger brother), while No. 53, is a 126 cm (49-1/2") high one hundred-and-eighty-year-old Japanese red pine in a grey-white glazed round container 84 x 41 cm (33 x 16").  This last tree is the only specimen from the Imperial Household to ever permanently leave Japan.  Following a planned quarantine period, the full Collection was finally made available for public viewing at the Bonsai and Penjing Museum at the National Arboretum in Washington, D.C. in July 1976. 16

       Meanwhile, back in Tokyo, in April 1976 seventy of the Imperial Collection bonsai were registered as national assets.  These particular trees are the ones most lent out for bonsai exhibitions, and those chosen being the ones that are frequently used in the Palace itself. 17

       Between April 6 and 9, 1989, the World Bonsai Convention was held at Ōmiya.  Its theme was "World Peace Through Bonsai."  Over twelve hundred enthusiasts from thirty-two countries gathered for the four-day event at which sixty Japanese masters in total gave demonstrations and workshops.  The formal inaugural meeting of the World Bonsai Friendship Federation was held during the Convention.  The program also included an exhibition of twenty-three representative trees from the designated group of three hundred trees in the Important Bonsai Masterpieces maintained by the Japanese government as part of the Imperial household.  These bonsai represent the highest level of artistic, scientific and historical value and are usually only on display inside the Palace grounds -- not often seen by the general public.  The trees are displayed with dignity and grace in valuable antique bonsai containers.  They are the work of generations of artists and are truly a national cultural heritage.  Kichō ("valuable") bonsai are registered in the list which the Nippon Bonsai Association compiles.  Kichō bonsai exist all over Japan.  In addition, ten bonsai and ten bonki (bonsai utensils) from the Imperial household were displayed on this occasion.

       Per Jerry Stowell: "Another bonsai that I remembered from [March] 1967 was a Japanese yew [Taxus cuspidata], multiple trunk style, that our group was privileged to see on the Imperial Palace grounds, where the Imperial Collection is located.  This tree had several driftwood, upright trunks that looked more like twigs and sparse foliage in a brick red, unglazed, rectangular, cloud-footed container.  The tree did not seem to be worthy of the Imperial Collection.  It had little style nor the age of many of the other trees we saw that day.  However, I kept these thoughts to myself all these years not expecting to ever see the tree again.  To my surprise and delight, it was on display with other trees and containers from the Imperial Household at the World Bonsai Convention.  It had matured, was well shaped with a layered effect and now looked like a forest.  The main trunk seemed taller and the base had taken on an aged appearance.  It seemed worthy of the Imperial Collection." 18

"In this photo released by the Imperial Household Agency,
Japan's Emperor Akihito (L) and Empress Michiko

       "...There is always a representative of the Imperial Bonsai at each Kokufu Bonsai Exhibition.  This year [2011, there] was a Japanese black pine.  There was also one at the Sakufu Bonsai Exhibitions in December as well.  In the past, when Princess Chichibu was around, she always had a bonsai on display, as well as other members of the Imperial family too.  This year the Crown Prince came alone, wife ill..."

       At the Asia-Pacific Bonsai & Suiseki Exhibition and Convention (ASPAC 2011) in Takamatsu from November 18-21, 2011, there were two trees from the Japanese Imperial Garden on display. 19

       "Both the pots and trays used to contain bonsai are known in the Palace as bonki (bonsai utensils) and there are said to be over three thousand of them.  Most of those dating back before the Pacific War used to be kept in the Imperial Household Museum, but when this became the National Museum custody of them was transferred to the Horticultural Division of the then Imperial Household Ministry.  Today both bonsai and bonki are taken care of by the Imperial Household Agency's Gardens Section...
       "There are pots among them that crossed the sea to Japan in ancient days as early imports from China and Nanking porcelain, but the really characteristic features of the Palace bonki can best be seen in the native Japanese pots... produced in every region of the country.  No less than twenty-four of these important bonki were registered as national assets in 1973...
       "In the olden days the more famous artisans did not normally turn their hands to making pots for bonsai, but they would do so if it was on order from or for presentation to the Imperial Household.  ...there are pots bearing the Imperial Family crest that are only to be found in the Palace.  These were specially commissioned in Okinawa by the bonsai-loving Prince Fushimi for presentation to the Imperial Household in 1908." 20

       "At New Year, in accordance with an old tradition, the Private Apartments are decorated with special bonsai creations known as haru-kazari.  This tradition has been handed down from the old days, and by the time of the Emperor Kohmei (1844-66), the preparation of these haru-kazari was one of the regular year end events...
       "To create a haru-kazari, a plum bonsai with either red or white flowers of the type known as kohaku ume was planted in a brocade pattern Imari pot together with special varieties of bamboo and other plants considered to have an auspicious significance, the surface of the soil being then strewn with black Nachiguro pebbles."  (Pine, bamboo, and spearflower (Ardisia crispa) were planted with ume for the haru-kazari welcoming 2011.)
       "On the 30th day of the last month of the year, ...senior members of the government would visit the palace to pay their final respects, and after this had been completed, in the afternoon of the 31st, the New Year haru-kazari were set up simultaneously in the drawing-rooms of Their Imperial Majesties, the Empress Dowager, the Crown Prince, and the princes of the blood.
       "Some parts of this tradition dating from the beginning of the Meiji Era have now been discontinued.  But for haru-kazari today, splendid group plantings of pine, bamboo, and plum (the celebrated "Three Friends of Winter") are created in the Ōmichi Bonsai Shitate-ba just as they were in the old days.  In one corner of the bonsai store there is a long row of red and white flowered plum bonsai ranging in height from 170 cm to two meters (67" to 79").  On the 5th or 6th of December the plum trees with their tiny buds still tightly closed are put into the hothouse to begin getting ready for the New Year.  Every year before the close of work on December 28th, about forty of these pine, bamboo, and plum groups are prepared by the specialist staff of the Shitate-ba.  Only when these have been delivered to the Fukiage Imperial Residence, to the Palace, and to the residences of the princes of blood, can the Bonsai Shitate-ba welcome the New Year."  (In 2010 the media was allowed to report the work on 24 December when the work was in the final stage, which then had the haru-kazari set up on 30 December.) 21

22.    Lanmen, Janet  "Yasuji Matsuda Visits National Bonsai Collection," Bonsai Magazine, BCI, May/June 1985, pg. 20; Poole  "Japan's Imperial Palace," pg. 104; Per "Early History, Hakone -- the Early Years," (©2013 Hakone Foundation), "Renowned architect Tsunematsu Shintani was selected to design the Upper 'Moon Viewing' House in 1917 and landscape gardener Naoharu Aihara, born to a family of Imperial gardeners in Koyobashi, Tokyo, designed the gardens.  The Lower House was built in 1922."  This mirrors a Google snippet from The California Horticultural Journal, 1974, Volumes 35-36, pg. 142, which has "Hakone's Japanese garden, comprising about three - and - one - half acres, was designed by Naoharu Aihara, an immigrant landscape gardener who is said to have come from a family of imperial gardeners in Tokyo.  It dates from 1918."  Per The East, 2005, Vol. 41, pg. 21, Aihara lived from 1870-1940.

In the Wikipedia article Biota of Tokyo Imperial Palace (accessed 10/10/2014), it is stated that:
"In 1921, the plants in the Palace were inventoried and published in Imperial Palace Landscape.[In Japanese language only: Kyujo Fuchi Ko by Yukio Ichikawa]  This was the first survey of the plants of the Palace.  Surveys continued in 1979 (Fukiage Garden), 1980 (Imperial Palace West Block), 1981 (East Gardens), and in 1987-88 (aquatic organisms in moats and ponds).  These reports are not available to the public, but provide precise information about the vegetation, its time-course changes, old historic and giant trees.  Further surveys started in 1996.  The survey of living organisms was reported in 2006. [Biology Study Group[20018-9]]"

It would be interesting to learn if any of the bonsai were included in these surveys.
