SQL & PL/SQL

Hi,

Our database is UTF8 enabled infact we are using AL32UTF8 encoding. When we are running the following query then the results are displayed in Japanese instead of English for the 'DAY' and 'DY' clause.

SELECT TO_CHAR(SYSDATE,'DAY') DAY,TO_CHAR(SYSDATE,'YEAR') YR,TO_CHAR(SYSDATE,'DY') DY,TO_CHAR(SYSDATE,'MON') MON FROM DUAL;

DAY YEAR DY MON
-------------------------------------------------------------------------
火曜日 TWO THOUSAND SIX 火 JAN

Can anyone please tell me what is the reason behind this. Our other nls parameters are like;-
SQL> sho parameter nls

NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
nls_calendar string
nls_comp string
nls_currency string
nls_date_format string
nls_date_language string
nls_dual_currency string
nls_iso_currency string
nls_language string AMERICAN
nls_length_semantics string BYTE
nls_nchar_conv_excp string FALSE
