Technical Tours

Two technical tours of lead and zinc plant operations in Japan are arranged and they take place beginning on Thursday, Oct. 20, 2005, the next day after the symposium.
These tours are restricted to registered participants, who will get a more detailed program at the information desk.

  1. Technical Tour bound for West Japan, Oct. 20-21
    Technical Tour No.1 covers two smelters/refineries and two companies of application of lead and zinc located along the coast of the inland sea in west Japan for two days, which includes the ISP lead and zinc operations in Harima Smelter, Sumitomo Metal Mining Co., Ltd. and the lead operation in Takehara Refinery, Mitsui Mining and Smelting Co., Ltd., a lead-acid battery plant in GS Yuasa Corporation, and a galvanizing zinc plating operation in Kakogawa Works, Kobe Steel, Ltd. This tour is a two-day bus trip, stating from Kyoto TERRSA lobby (conference place) and returning there in the evening of Oct. 21. It may be strongly advisable that you make the lodging reservation for the night of Oct. 21 in Kyoto or so, considering the return flight schedule from Kansai International Airport. The fee includes the bus travel expense and one night lodging (Oct. 20) with dinner and breakfast.
  2. Technical Tour bound for East Japan, Oct. 20-22
    This tour covers the zinc plant in Iijima Refinery, Akita Zinc Co., Ltd., the lead plant in Kosaka Smelting & Refining Co., Ltd, and the ISP lead and zinc operations in Hachinohe Smelting Co., Ltd. This tour is a three-day trip by airplane and bus, starting from Kyoto TERRSA lobby (conference place) on Oct. 20 and returning there in the late afternoon of Oct. 22. This season of a year in the Tohoku mountain area is the prime of colored leaves, which you can enjoy as well as the plants tour. The fee includes all the travel expenses of round trip from and to Kyoto TERRSA and two night lodgings with dinners and breakfasts (Oct. 20 and 21). It may be advisable that you make the lodging reservation for the night of Oct. 22 in Kyoto or so, considering the return flight schedule from Kansai International Airport.

Accompanying Persons' Programs

  1. Japanese Culture Experience / Oct. 17 and 19, Morning
    At Kyoto Terrsa, accompanying persons' program gives you the great opportunity to experience Japanese cultures such as the tea ceremony, flower arrangement, calligraphy, or wearing Kimono. Accompanying persons who plan to enjoy this program may apply to the information desk at the front lobby.
    The tea ceremony is an ideal way to experience typical Japanese aesthetics. In the course of flower arrangement, you can enjoy the unique Japanese styles of flower arrangement and compare them with Western styles. With traditional brushes and India ink, you can try writing your names and some interesting Japanese characters "Kanji". The deluxe course of wearing Kimono will give women a chance to wear Komon (short sleeved casual kimono) and men a chance to try the Kinagashi Kimono (casual kimono for men). Each course will last for 2 hours, and are arranged in Kyoto Terrsa in the morning on Monday and Wednesday. The program is covered by in the accompanying persons' registration fee.
  2. City Tour / Oct. 18, Afternoon, Optional
    Another program of "City Tour" described below gives the option of sightseeing with an English-speaking guide in the afternoon on Tuesday. The tour departs from the front gate of Kyoto Terrsa. The ticket for this tour is not included in the registration fee. Planning to join this optional tour, please contact to the information desk at the front lobby by 18:00, Oct. 17.
    This tour includes the Sagano sightseeing tram from Saga torokko station to Kameoka torokko station and rapid shooting on the Hozukyo River from Kameoka to Arashiyama. You can enjoy the open-air tram offering a cooling, refreshing recreation ride. Even the latest-model tram, "The Richi," features an open grid floor, so passengers can look out of the scenic window view while feeling the natural breeze. After the tram riding, you experience an exciting 16 kilometer, ninety-minute trip downstream, shooting the Hozu Rapids aboard a flat-bottomed boat from Kameoka to scenic Arashiyama. The changing in beauty of the winding gorge leaves unforgettable memories.
