対訳形式の和文はこちらをどうぞ。 ↓ http://www.mumyouan.com/k/?M1103 ＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿ ********* The cutting targets that are used, seen in non-Japanese tameshigiri videos are Chinese-made "mock" tatami omotes sold outside Japan for tameshigiri(test cutting). Firmness and density differ very much from those of Japan stuation. Nearly 2-jo(jo: 90cm X 180cm) roll or 3-jo roll of Chinese tatami omote amounts to 1-jo roll of Japanese tatami omote. The length of foreign tatami omote is longer than Japanese one, they are well over 120cm, compared to 90cm Japanese tatami omote. The sound when cutting the Chinese-made mock tatami omote like beach mat, sold in USA, is completely different from that made in Japan. By cutting soft low density makiwara(cutting target made by rolling the tatami-omote), the sound will be like "PASUN." However when cutting hard high density makiwara, the sound will be with higher pitch like "PYU." ************ The recent official rule applied in the Guinness World Records are as follows: 1- The makiwara used must be Japanese-made. 2- The makiwara must be tightly rolled so there will be no hollow space at the center. The diameter must be between 8cm to 9cm, and should not be over 9cm. 3- Note that the makiwara roll must be tied at 3cm from the grounding position. This is because the higher the tying position,the roll will be more loose at the bottom, and the surface area touching the ground will be larger making the roll more withstanding from falling down. 4-The length of tatami omote is 90cm. 5-If a tip of the katana touched a floor, it is disqualification. Additional condition for the application_ 6- The sakikasane (thickness not counting the shinogi thickness) of the katana is more than 5.5mm, and the hawatari (length of the blade part) is to be longer than 2.4shaku(72.7cm)for a person as tall as 170cm. The katana used must be shinogi-zukuri Japanese katana. The condition is that it must be true Japanese katana with good meat(niku), hiraniku and haniku.
