Eating Uguisu Mochi (鶯餅) in Anticipation of Japan`s most Famous Sound of Spring- The cry of the bush warbler (uguisu)

Japan's spring songster

Japan’s most celebrated spring songster– the UGUISU (Japanese bush warbler)

Traditional spring sweets on display- the light green oval shaped ones in the center are UGUISU MOCHI

While the early plum blossoms are beginning to burst open, providing us with the encouraging SIGHTS and SMELLS of spring, we have yet to hear the CALL, which in Japan has traditionally signaled the fact that spring has arrived in earnest — the cry of the male UGUISU (鶯), or bush warbler. The Japanese have long heard this distinctive chirp, which is actually a mating call, as HO-HOKEKYO (法 法華経), which also happens to be the name of one of Japanese Buddhism’s most famous sutras, the Lotus Sutra. Hear the actual sound here.

The sudden appearance of this melodic expression of avian yearning has been an inspiration for some of Japan’s greatest spring poems, though the bird itself is quite plain (with dull brown plumage) and is in fact, quite difficult to spot.

Uguisu Mochi

A bird in the hand- Uguisu Mochi!

Since the Edo Period (1600-1868), the Japanese have anticipated the first calls of the bush warbler (which is often translated into English using the more poetic sounding NIGHTINGALE), by eating a traditional sweet (wagashi) called UGUISU MOCHI (鶯餅). These are slightly oval-shaped rice cakes, sprinkled with green soy bean powder and filled with bean-paste, which are meant to suggest, rather abstractly, the birds of famous song. For me, it is ironic, however, that the green soy bean powder (in the Edo Period green tea powder was actually used), makes the sweets more reminiscent of the beautiful MEJIRO, or Japanese white-eye, than of the dull colored bush warbler. Since few people can actually recognize the UGUISU by sight, I guess that nobody takes note of this .

Uguisu Mochi will be on sale at WAGASHI SHOPS (traditional Japanese sweet shops) through mid-March. They can be bought individually, or as part of a set containing other early spring treats such as sakura mochi and yomogi mochi.

There is one more point I’d like to make. In Japanese culture there are certain traditional pairings of flowers and birds — with one of these being UGUISU and PLUM BLOSSOMS (梅にうぐいす ume ni uguisu). Because of this, the bush warbler and plum tree are often depicted together as a spring motif in Japanese arts and crafts. The fact is, however, that you will not very likely see UGUISU on a plum branch, as these shy birds  usually remain within the shelter of bamboo groves and woods. Within the next few weeks, however, you are more than likely to hear their famous call.

A fresh batch of UGUISU MOCHI- beautiful, delicious, and a sign of good things to come!

    According to the season, some Japanese traditional sweets change!! We can have the feeling of Kisetsu-no-utsuroi (changing of seasons). Uguisu-mochi sound rather Shibui (literally bitter, but meaning something like chic, in French), and I enjoy it as I do sophisticated and charming company.
    .Avi-san `s photos nicely show the differece in color between the Uguisu and Mejiro. Like Yoshikiri, it is difficult to take photo of that Sopurano-singer.

    Uguisu-twittering training reminds me I should have much voice training for my male chorus. They began like Ho-ke-kyo-kyo—kyo, after many times singing they can shorten ke-kyo-kyo part and finally can sing Ho-Hokekyo beautifully, we are lucky to live Tsukuba area we can enjoy their singing just sitting inside our houses tasting green Tea!! (it is OK coke, Uron-tea, milk, cocoa, soda, tequila, whisky, aquavit, vodka, bourbon, cold-sake, distilled water )
    Another one and half month??!!. Momo, Sakura, Dango!

    Hello Avi sensei.
    I like a Uguisu Mochi.
    When I was a senior high student, I did the tea ceremony.
    We enjoyed tea and seasonal sweets.
    This article reminded me of old fun days.
    Thank you.

    Many young male birds can not correctly sing “Ho- Ho- Kekyo” in early spring but sing something like Ho-Kyoku GumaKyoku or “Hottoite Okyure Kekkou” or “ Tokyo Tokkyo Kyokakyoku” . After months of training they can proudly sing “Ho—Hokekyo, Kekyo Kekyo Kekyo.Kekyo Kekyo Kekyo….” I am always amazed by the long singing line of their call that you can hear in June and July.
    That is the time for Ume-shu (Plum Liquor) making. And the time to taste one-year old Ume-shu, has come to be called Umeshu!=meaning delicious.

    There is a Japanese children song about UGUISU and UME on YouTube. Try to paste the following to watch it:
